Legislation – Unions celebrate new pay transparency law

Source: NZCTU Te Kauae Kaimahi

The NZCTU Te Kauae Kaimahi is celebrating the passage of Labour MP Camilla Belich’s Employment Relations (Employee Remuneration Disclosure) Amendment Bill into law. The Bill will protect working people who want to discuss or disclose their pay.

“This Bill represents a significant step towards pay transparency for workers. We are thrilled that is has been supported across the House and will now become law,” said NZCTU Secretary Melissa Ansell-Bridges.

“Illegal and unfair pay gaps are a huge problem in this country. This is in part because employers have imposed a culture of secrecy around pay. Often workers have had no way of finding out if they are being paid what they're worth.

“Pay secrecy has shielded unfair and unlawful practices that should be brought to light.

“Workers have a right to discuss their own pay rates with whoever they please. Their pay is their own business. Bosses should not be able to impose secrecy over personal information.

“Unions have been campaigning for pay transparency because it is a step towards a culture of openness in workplaces. It will help address persistent pay gaps.

“At a time when working people are facing relentless attacks, it’s great that we can take a moment to celebrate a win,” said Ansell-Bridges.

Economy – OCR cuts don’t appear to be over yet – Cotality

Source: Cotality – Kelvin Davidson, Chief Property Economist for Cotality NZ (formerly CoreLogic)

The Reserve Bank’s Monetary Policy Committee went ahead with a 0.25% official cash rate (OCR) cut today, as widely expected. This decision was pretty clearly signalled at the last meeting in early July, and the economic (weak) and inflation (rising but not critically) figures have evolved broadly as expected in the meantime.
The Committee also discussed a rate hold as well as a 0.5% cut, with the vote ending up 4-2 in favour of the 0.25% drop. This menu of options has a ‘downwards bias’ and pretty clearly suggests that they envisage further rate falls yet.
Indeed, the forecasts that came alongside the Monetary Policy Statement (MPS) showed GDP may not have bottomed out yet (possible -0.3% drop in Q2) and that the unemployment rate could still rise a little further. Inflation could go a bit higher, due to the tradeable/imported component, but spare capacity in the economy should mean this doesn’t last.
It seems fair to conclude from these projections that another one or even two OCR cuts lie ahead, with the first potentially delivered at the next MPS on 26th November. That will be the last meeting for the year and could be an opportunity to support households further over the holiday period, given that the first decision for 2026 doesn’t occur until late February. Note that the Reserve Bank’s own forecast track for the OCR has it reaching a trough of somewhere close to 2.5% by the middle of next year.
The housing market effects from today’s decision are likely to be small. If anything, the possibility of more falls in mortgage rates than previous thought could lift activity and house prices a bit. But those rate changes may be fairly minor. And in the meantime, as the RBNZ has indicated, the economic and labour market outlook is still disappointing – which will tend to weigh on housing, as it’s already doing.
Those concerns about job security might mean that many existing borrowers who are rolling off higher fixes from the past and down onto the new prevailing mortgage rates might choose to save their extra cash or reduce the term of their loan (by keeping repayments the same) rather than spend it in the economy or property market. All in all, the rest of 2025 for NZ’s housing market may be just as subdued as the first 7-8 months of the year.

Economy – OCR lowered to 3% – Reserve Bank of New Zealand

Source: Reserve Bank of New Zealand

OCR lowered to 3% – Monetary Policy Statement and the MPC’s record of meeting, which summarises the committee's discussions, leading to the decision.

Annual consumers price index inflation is currently around the top of the Monetary Policy Committee’s 1 to 3 percent target band. However, with spare capacity in the economy and declining domestic inflation pressure, headline inflation is expected to return to around the 2 percent target midpoint by mid-2026.

New Zealand’s economic recovery stalled in the second quarter of this year. Spending by households and businesses has been constrained by global economic policy uncertainty, falling employment, higher prices for some essentials, and declining house prices.

There are upside and downside risks to the economic outlook. Cautious behaviour by households and businesses could further dampen economic growth. Alternatively, the economic recovery could accelerate as the full effects of interest rate reductions flow through the economy.

The Monetary Policy Committee today voted to decrease the Official Cash Rate (OCR) by 25 basis points to 3 percent. Further data on the speed of New Zealand’s economic recovery will influence the future path of the OCR. If medium-term inflation pressures continue to ease as expected, there is scope to lower the OCR further.

Summary record of meeting – August 2025

Annual consumers price index inflation remains within the Monetary Policy Committee’s 1 to 3 percent target band. Recent increases in food prices and administered prices have contributed to near-term inflationary pressure. However, domestic activity has been subdued and there remains significant spare productive capacity in the economy. Headline inflation is expected to return to around the 2 percent target mid-point by mid-2026. If medium-term inflation pressures continue to ease as expected, there is scope to lower the OCR further.

Annual CPI inflation remains within the target band

Annual consumers price index (CPI) inflation increased to 2.7 percent in the June 2025 quarter. Headline inflation is expected to reach to 3.0 percent in the September 2025 quarter, reflecting large increases in administered prices, food prices, and the prices of other tradable goods and services.

Surveyed measures of medium-term inflation expectations remain near 2 percent, consistent with the mid-point of the target band. Non-tradables inflation has continued to decline in aggregate. Measures of core inflation have declined and are within the target band. Headline inflation is expected to converge to the mid-point of the target range over the next year as tradables inflation pressures dissipate and significant spare capacity continues to reduce domestic price pressures.

Near-term inflation expectations have increased, particularly for households. Household inflation expectations have risen across several advanced economies and may be influenced by global factors such as increased trade restrictions, as well as relatively large increases in some prices such as those for food and energy.

Tariffs and economic policy uncertainty are dampening the global economic outlook

Evidence to date suggests that the global economy is responding broadly as expected to trade restrictions and policy uncertainty. Growth in some of our trading partners, particularly China, was higher than expected in the second quarter of 2025 but is expected to moderate in the coming quarters. Headline inflation has increased moderately in some advanced economies but is declining in most of our Asian trading partners.

Tariffs are causing changes to global trading patterns but have so far had a limited effect on aggregate global trade volumes. To date, there is no evidence of major disruption to global supply chains, or a material impact on the prices of New Zealand’s imports or exports. The Committee noted that it continues to expect that the increase in global trade restrictions will result in less inflationary pressure in the New Zealand economy.

The effective tariff rate on New Zealand exports to the United States is higher than anticipated at the time of the May Statement. Some firms and industries may experience more challenging export conditions as a result. The medium-term implications for New Zealand will depend on how global demand responds to increased trade restrictions and economic policy uncertainty.  

Economic growth in New Zealand is expected to recover gradually

High-frequency indicators suggest that the New Zealand economy contracted in the second quarter of 2025 and was weaker than expected at the time of the May Statement. Growth is expected to resume in the September quarter, consistent with a recovery in some economic indicators for July. A key judgement for the Committee’s economic assessment was the extent to which spare capacity in the New Zealand economy is likely to persist.

The Committee discussed constraints on household wealth and discretionary income. Employment and hours worked have declined, and wage inflation has slowed sharply over the last year. Household dissaving since the start of 2022 has reduced savings buffers. At the same time, inflation in some essential expenditure components such as food, gas, electricity, and council rates has been much higher than the general rate of inflation. These factors were noted as likely to contribute to a slower recovery in domestic spending than would otherwise be the case.

House prices have declined to a level within the Reserve Bank’s range of sustainable house price estimates. Housing is a key component of household wealth, which influences household spending. Ongoing weakness in the housing market is contributing to subdued residential construction and household consumption.

The Committee discussed the fiscal outlook. Declining government spending as a share of the economy is expected to reduce inflationary pressure in the medium term. This is consistent with the economic and fiscal projections published in the Budget Economic and Fiscal Update 2025.

The Committee acknowledged regional and sectoral divergences in economic activity. House price growth has varied considerably across regions. High commodity export prices are supporting activity in the agricultural sector, resulting in stronger spending in rural areas. However, to date, many agricultural businesses have used higher export revenues to pay down debt, limiting the pass-through to consumption and investment.  

There is significant spare capacity in the New Zealand economy

A broad range of indicators suggest that significant spare capacity in the New Zealand economy persists. Unemployment has increased, as have measures of labour underutilisation, and firms are reporting that it is relatively easy to find labour. Firms are also reporting low levels of capacity utilisation. The Committee noted that while credit is generally available, growth in business lending has been slow.

The Committee discussed slow growth in the productive capacity of New Zealand’s economy. Potential output growth has slowed, reflecting subdued investment, low productivity growth, and historically low population growth through net immigration. The Committee noted that appropriate monetary policy settings would support sustainable long-run investment and growth.

Monetary policy continues to transmit through the financial system

The Committee noted that wholesale interest rates have fallen since the May Statement, resulting in lower mortgage and term deposit rates, particularly at shorter terms. The average interest rate on the stock of mortgages is expected to continue to decline over the coming year, as about half of existing mortgages are expected to re-fix onto lower rates over the next six months. This will reduce debt servicing costs for households as past reductions in the OCR continue to transmit through the financial system.

Long-term bond yields have increased internationally over the first half of the year, with higher term premia reflecting geoeconomic uncertainty and elevated debt levels. Despite subdued domestic activity, the New Zealand dollar TWI has been relatively stable through this period, in part due to policy developments and declining short-term interest rate expectations in the United States. Equity prices in the United States have been elevated, but this has largely been attributable to the out-performance of a few large technology firms.

The financial system remains stable

The Committee was briefed on financial system stability. Subdued demand and low profitability are contributing to financial stress for some businesses. Non-performing loans for households and businesses have increased but remain low relative to previous cycle peaks. Increased provisions and strong capital buffers mean that banks are well-prepared to absorb any losses. The Committee noted that monetary policy settings that support growth in the economy will also contribute to financial stability.

There are upside and downside risks to the economic outlook

The Committee expects headline inflation to remain within the target band over the forecast horizon. However, with inflation projected to increase to 3.0 percent in the September quarter, there is a material possibility that it rises above the target band. The period in which this is most likely to occur is too soon for monetary policy to have any meaningful effect. However, if inflation were to remain higher for longer than expected, there is a risk that this influences inflation expectations and wage- and price-setting behaviour over the medium term.

The Committee noted that increases in administered prices, such as local council rates and some energy charges, have contributed to higher-than-otherwise non-tradables inflation. Some members emphasised that these prices represent rising costs for businesses and may spill over to generalised non-tradables inflation, particularly in the near term. Other members emphasised spare capacity and weak demand, which would limit the ability of firms to pass on cost pressures to consumers.

Some members also drew attention to slow growth in parts of the economy that are most sensitive to interest rates. Residential construction, house prices, and retail activity have not materially recovered, despite monetary easing to date. On a quarterly basis, non-tradables inflation excluding central and local government charges is consistent with inflation at or below the target mid-point. Some members suggested that this may represent a downside risk to medium-term inflation. Other members emphasised that previous reductions in the OCR continue to transmit through the financial system and will take time to have their full effect on activity and inflation. Growth in interest-rate-sensitive sectors of the economy is projected to recover over the remainder of this year.

The Committee discussed the extent to which uncertainty associated with global trade restrictions is likely to limit domestic demand and inflationary pressure in the medium term. Consumption and investment demand appear to have weakened in the second quarter of 2025, partly in response to heightened trade policy uncertainty. The effects of uncertainty on domestic activity are assumed to persist over the remainder of the year. Some members emphasised the fact that some measures of uncertainty have improved considerably since May and noted a possibility that the domestic economy recovers more rapidly as the effects of uncertainty dissipate. Other members highlighted that excess supply in China and some parts of emerging Asia has the potential to lower tradable inflation in New Zealand over the medium term.  

Some members also emphasised the risk that precautionary behaviour by New Zealand households and businesses may result in a weaker consumption and investment outlook than assumed, particularly in the context of slow growth in household wealth and discretionary incomes and low firm profitability. In this environment, businesses that are uncertain about potential future demand are less willing to invest, which in turn lowers potential growth and could further prolong uncertainty about future incomes and wealth. It is possible that pessimistic sentiment, together with the initial negative effects of the global tariff shock, have dampened the effects of the reduction in the OCR since last August.

The Committee noted limits to the ability of monetary policy to influence expectations of long-term growth. Some members emphasised that near-term support from monetary policy is most effective when combined with regulatory and policy settings that promote innovation and investment to support productivity growth.  

The Committee voted to reduce the OCR to 3 percent

The projected path of the OCR reflects the Committee’s central expectation of the path needed to ensure that inflation settles sustainably near the target mid-point. Uncertainty about the future path of the OCR is reflected in the Committee’s discussion of upside and downside risks to the outlook. Some members considered the balance of risk to be to the upside relative to the projected path, while others considered the balance of risk to be to the downside.

The Committee discussed three policy options: keeping the OCR on hold at 3.25 percent; cutting the OCR by 25 basis points to 3 percent; or cutting by 50 basis points to 2.75 percent.

The case for holding the OCR steady at 3.25 percent focused on positive influences on growth. Global economic activity outside of the United States has so far proven resilient in the face of new trade barriers, and global policy uncertainty has reduced from its peaks in April and May. The full extent of recent monetary easing is yet to fully transmit through the economy. Although high-frequency indicators suggest weak economic activity in the June 2025 quarter, available indicators for July suggest some improvement. With inflation approaching the top of the target band, and near-term inflation expectations rising, it could be prudent to pause to observe incoming data. One member gave relatively more weight to this view.

The case for lowering the OCR by 50 basis points to 2.75 percent emphasised declining inflationary pressure and significant spare capacity. Some members put relatively more weight on the risk that the negative consequences of global policy uncertainty on domestic consumption and investment are self-reinforcing and therefore more persistent. A larger reduction in the OCR might disrupt such a dynamic and generate clearer signals that support consumption and investment, whereas a gradual reduction in the OCR might not provide the same positive signalling effect. These members also emphasised that weakness in the labour market and excess capacity limits the upside risk to inflation should the economy recover more quickly than projected.

The case for lowering the OCR by 25 basis points to 3 percent was based on the upside and downside risks around the central projection being broadly balanced. Financial conditions are continuing to respond to past reductions in the OCR. They are also influenced by expectations of the future path of the OCR, which provides sufficient signalling effects. If medium-term inflation pressures continue to ease in line with the Committee’s central projection, the Committee expects to lower the OCR further. Reducing the OCR by 25 basis points at this meeting provides the opportunity to adjust this view incrementally in response to new information.

On Wednesday 20 August, the Committee voted on the options of either reducing the OCR by 25 basis points or reducing the OCR by 50 basis points. By a majority of 4 votes to 2, the Committee agreed to decrease the OCR by 25 basis points to 3 percent.

Forestry Sector – Why carbon forestry rules won’t work – Federated Farmers

Source: Federated Farmers

Federated Farmers says the Government’s proposed rules to limit whole-farm conversions to carbon forestry are far too weak to stop the damage being done to rural New Zealand.
“The draft rules have completely missed the mark,” says Federated Farmers forestry spokesperson Richard Dawkins.
“As they’re currently drafted, the proposed regulations will barely make a dent in the number of whole-farm conversions to carbon forestry.
“Unless Minister Todd McClay steps in and makes urgent changes, we’ll continue to see our productive hill country swallowed up by permanent pine forests at an alarming rate.”
The Government’s proposal is to cap the amount of farmland that can be registered in the Emissions Trading Scheme (ETS) at 25%.
But that limit applies only to land use capability (LUC) classes 1 to 5 – the land least likely to be targeted for carbon farming in the first place.
“The reality is that only 12% of recent carbon farm conversions have happened on this kind of land anyway,” Dawkins explains.
“The remaining 88% have occurred on class 6 and 7 land, which is where most of New Zealand’s sheep and beef farmers also happen to operate.
“These are not marginal blocks of scrub or waste. They’re productive, resilient hill country farms – the backbone of our red meat industry and a vital part of our food production system.
“Under the new rules, those farms will get next to no protection.”
The Government is instead proposing a 15,000-hectare annual cap for class 6 land and leaving class 7 unrestricted – a move Dawkins calls ineffective and unfair.
“There’s just too much sheep and beef land without protection for it to be effective,” Dawkins says.
“It will be business as usual for the big polluters and foreign investors looking to blanket rural New Zealand in pine trees.
“This kind of timber doesn’t generate jobs, export earnings or regional development. It’s speculative carbon farming.”
He says the system allows big urban emitters to buy their way out of reducing emissions while rural communities shoulder the long-term costs and consequences.
“Once you lose a productive sheep and beef farm to carbon forestry, it’s gone for good.”
He says the Government’s goal of doubling exports by 2030 is at risk under the proposed rules.
“Red meat is a cornerstone of our export economy, bringing in around $12 billion annually,” Dawkins says.
“With strong prices and advances in genetics, pasture management and technology, we should be focused on improving productivity and lifting output – not losing ground.”
Dawkins is calling on Forestry Minister Todd McClay to act.
“If this Government is serious about reining in whole-farm carbon conversions, the 25% cap must apply to all land classes – including classes 6 and 7.
“Our national values, our future as a food-producing nation, and the resilience of our rural communities are all on the line.
“We’re about to find out whether this Government truly stands with rural New Zealand or if this Bill is just political spin.”

Emergency Responses – NEMA identifies what caused emergency alert issues during Kamchatka tsunami event

Source: National Emergency Management Agency (NEMA)

 

The National Emergency Management Agency says it has got to the bottom of the issues reported by the public during the Kamchatka tsunami event of 30-31 July, when NEMA issued Emergency Mobile Alerts to warn people of dangerous tsunami activity in coastal areas.

 

NEMA’s Director Civil Defence Emergency Management John Price says the systems that issued and transmitted the alerts worked well on the day – and that public safety was at the centre of the decision to issue alerts. He says NEMA has now identified why some people received multiple alerts, or no alerts at all.

 

John Price says these issues are largely down to how different mobile devices behave, and the decision to send the alerts only to cellphones in coastal locations.

 

“First of all, we know explanations are little consolation for those who were awoken by alerts in the middle of the night. We are very sorry that this happened, and we’re looking at ways to address this in future. However, we make no apologies for getting the message out to keep people safe.

 

 

“NEMA only issued two alerts – at 4.13pm on 30 July and 6.30am on 31 July – but some people received multiple alerts during the night. We’ve discovered this is likely related to overnight software updates and device settings.

 

“As for those who didn’t receive alerts – tsunami alerts are only sent to coastal areas, so if you were inland then we didn’t send you the message because you were not at risk.

 

“The good news is that there is no problem with the systems we use to send the messages. The alerts were effective in reaching the targeted coastal areas and getting the message out to stay away of the water while dangerous tsunami activity was happening.

 

“We sent alerts to over three million mobile devices around the country, and when you consider the sheer variety of makes, models, and software, it’s inevitable some variations will emerge at the receiver end.

 

“After every emergency, we debrief to identify what went well and what needs to improve. We’re working through this now to ensure we’re doing the best we can at keeping people safe from tsunami and other threats.”

 

John Price says over 30 countries have cell broadcast alerting systems similar to New Zealand’s, and they have proven effective in alerting the public to severe and urgent threats to life, health or property.

 

“Emergency Mobile Alerts reach nine in ten people, so is a really reliable and effective way to get the message out so people know what to do to stay safe.”

 

Q&A

Why did I get multiple alerts?

Firstly – we are very sorry to everyone who found this disruptive, especially those who got woken several times in the middle of the night. This was not the intention and there are a few possible explanations.

  • When your phone does an automatic software update overnight it reboots. If you turn your phone off and on again during an alert broadcast, you will get the alert again. So when your phone reboots after an update, you will get the alert a second time.
  • During the early morning hours, some devices refresh their network connections. This process may have cleared cached data, prompting your phone to give you the alert again. While your device should recognise that it has already received and displayed the alert, it appears that some devices are more conservative and elect to redisplay. 
  • If you have multiple active Sims / eSims, you will get an alert for each Sim.
  • If your phone moved between 3G and 4G networks during the alert broadcast, you will get the alert again each time your phone connects to the new network. This can happen if you’re travelling into a poor coverage area, or if your phone drops in and out of networks.
  • Some phones have an optional alert reminder feature turned on. This can cause your phone to alarm repeatedly during the alert broadcast. If your phone does have this feature, you should be able to find it in your phone settings and turn it off.

As we don’t have any control over how individual devices behave, we can’t completely stop these issues from happening again – but we are looking at ways we can reduce their impact.

 

Why did I get the alert at a different time?

We issued the alerts at 4.13pm on 30 July – to warn that the dangerous tsunami activity would hit overnight – and on 6.30am the following morning – to warn that the activity was now hitting our shores. But we continued to transmit these alert broadcasts for several hours. This was so people entering the area later still got them.

You might have got an alert when commuting home at 5.30pm, or into work at 8am.

The most likely answer is that you were outside the coastal areas we sent the alert to. But then you entered the broadcast zone at a later time, triggering the alert on your phone.

So – if you took the 7am train from Upper Hutt to Wellington, you’d probably have received the alert around 7.20am as you entered Lower Hutt and into the coverage of the cell towers closer to the coast. Your fellow passengers may have received them at different times, depending on the location of their provider’s cell towers.

Or if your phone was off or in flight mode at the time the alert was sent, you would get the alert once your phone turned on or out of flight mode.

 

Why didn’t I get an alert?

Do you live in Hamilton? Palmerston North? Geraldine? Or perhaps an inland suburb of a coastal city?  Then don’t worry – we never sent it to you.

Emergency Mobile Alerts are sent to zones that are geotargeted based on where the risk from the hazard is. We identify the cell towers from all three telecommunications companies in the hazard area, draw a shape around them, and send the message to the area inside that shape.

Tsunami only impact coastal areas, so we issue alerts to geotargeted locations that are forecast to be impacted by the tsunami waves. For the Kamchatka event, we issued alerts to all coastal parts of New Zealand – but not to inland communities.  

Not inland? Check out our troubleshooting advice on why you might not have got an alert.

It’s important to remember that Emergency Mobile Alert is an extra channel to help keep you safe in an emergency. It does not replace other alerting systems or the need to take action after experiencing natural warning signs. Seek information from radio and other media, your local Civil Defence’s online channels, and trust your own danger sense if you experience natural warning signs such as a long or strong earthquake by the coast, or rising floodwaters.

 

Why did everyone in my house get the alert except me?

We get asked this a lot, and on the surface it must seem like something’s gone wrong. Usually there’s a straightforward explanation – you’re on the border of the geotargeted broadcast area.

The geotargeted areas aren’t a clean border. It dep

Geology – Discovery of Hidden Faults Sheds Light on Mystery of ‘Slow Earthquakes’

Source: Earth Sciences New Zealand

Discovery of Hidden Faults Sheds Light on Mystery of 'Slow Earthquakes' – “This is a major step forward in understanding the geological processes happening beneath our coastlines”
Scientists have uncovered a key piece of the puzzle behind the unusual ‘slow earthquakes’ occurring off the east coast of New Zealand’s North Island.
A new international study, published in Science Advances, identifies hidden fault structures called polygonal fault systems (PFSs) as a major influence on the behaviour of the northern Hikurangi subduction zone. These shallow geological features, found in sediments entering the subduction zone, appear to play a critical role in where and how slow slip earthquakes occur.
“This discovery helps explain why slow earthquakes occur where they do,” says Dr Philip Barnes, marine geologist at Earth Sciences New Zealand (formerly NIWA) and co-author of the study. “It also shows that these events may be influenced by the reactivation of old fault structures that formed much closer to the surface than the present depths of the subduction zone.”
In the Hikurangi subduction zone, the Pacific Plate is diving beneath the Australian Plate. While the southern section of this zone remains locked and capable of producing massive earthquakes over magnitude 8, the northern part behaves differently. It regularly produces slow slip events, movements that unfold over days to months, releasing tectonic stress without sudden shaking.
“Slow slip events do not cause violent shaking themselves, but they can increase stress on nearby faults and may trigger more damaging earthquakes. Understanding what controls them is vital to improving earthquake and tsunami warnings.”
The international study was a collaboration between researchers from China, the US, and Earth Sciences New Zealand, using data from the International Ocean Discovery Program and the high-resolution three-dimensional NZ3D seismic survey conducted off Gisborne. Using high-resolution 3D seismic imaging, deep-sea drilling data from the International Ocean Discovery Program, and advanced computer modelling, the research team was able to map out PFSs in unprecedented detail and to evaluate their role in the subduction zone.
“These faults form over millions of years during sedimentation, long before and initially away from the subduction zone. But as the seafloor is dragged into the subduction zone during the convergence of the tectonic plates, they can be reactivated and evolve into major thrust faults. Our analysis also shows they provide important pathways for fluids, which play a major role in fault slip.”
This connection between fault structure and fluid migration offers new insight into one of the key processes thought to trigger slow earthquakes, says Dr Barnes. The study also confirms that these fault systems create a complex and variable structure along the megathrust, which can influence stress patterns and strain distribution.
“Until now, we lacked the imaging resolution to link these features directly to slow slip behaviour,” says Dr Barnes. “This study changes that, and gives us a new lens to better understand subduction zone dynamics.”
While scientists first identified the PFS type of fault at subduction zones 20 years ago off the southwest coast of Japan, they couldn’t determine how these complex structures influenced subduction and seismic slip, says lead author Maomao Wang, a marine geologist at Hohai University in China. “It wasn’t until we analysed these beautiful 3D seismic images that we confirmed their widespread presence along New Zealand’s north Hikurangi margin, revealing their potential role in shaping slow earthquakes.”
The findings may also have implications beyond New Zealand. “Similar fault systems have been observed in subduction zones around the world, including Japan’s Nankai Trough. By highlighting the mechanical and hydrological effects of PFSs, the study adds a missing piece to the global understanding of how slow earthquakes work.”
“This is a major step forward in understanding the geological processes happening beneath our coastlines,” says Dr Barnes. “With better models and better data, we are now in a stronger position to understand how subduction zones work.”

Education and Employment – Teachers strike important to ensure quality education – NZCTU

Source: NZCTU Te Kauae Kaimahi

The NZCTU Te Kauae Kaimahi is today supporting PPTA members across the country who are striking for fair pay increases, more subject specialist advisors, and greater teacher-led professional development funding.

“The union movement stands in solidarity with secondary teachers who are fighting for a quality education system,” said NZCTU President Richard Wagstaff.

“Workers never make the decision to strike lightly. PPTA members are rightly taking action to ensure that schools can attract graduates and retain experienced teachers.

“It is unacceptable that teachers are being offered the lowest pay increase in a generation at the same time as they are facing an overhaul of NCEA.

“A quality education system affects all of us. Students, parents and communities all benefit from teachers having what they need to support our young people.

“The Government is prioritising tax cuts for the rich over essential public services. Everyone should be grateful to the teachers who are taking strike action this week,” said Wagstaff.

Legislation – Law change could save farmers and taxpayers millions – Federated Farmers

Source: Federated Farmers

Federated Farmers is throwing its support behind a new Member’s Bill that could bring much-needed clarity to New Zealand’s climate change laws – and save millions in legal costs.
National MP Joseph Mooney’s Climate Change Response (Restriction on Civil Proceedings) Amendment Bill aims to confirm a common-sense principle: if a person or business is complying with national climate change laws, they can’t be sued for causing climate-related damage.
“It sounds very obvious, but that’s not how the law appears to be working right now,” Federated Farmers climate change spokesperson Wayne Langford says.
“It’s crazy that companies like Fonterra and Dairy Holdings, who are fully meeting their legal climate obligations right now, can still be dragged into court and sued for allegedly causing harm through emissions.
“We fully support Joseph Mooney’s Bill, which will restore some much-needed common sense and save farmers, food processors and taxpayers millions of dollars in court costs.”
Climate activist Mike Smith is taking seven major New Zealand companies, including Fonterra and Dairy Holdings, to court over their greenhouse gas emissions.
He says the emissions are harming Māori land and culture, and is claiming public nuisance, negligence, and breach of a duty to stop contributing to climate change.
The High Court threw out two of the claims but allowed the third to proceed.
After appeals from both sides, the Supreme Court has now reinstated all three claims, allowing the case to go to trial, and the matter is now back in front of the High Court.
Federated Farmers says the case sets a dangerous precedent.
“Every New Zealander contributes to climate change in some way,” Langford says.
“When you turn on a light switch, cook dinner, drive your car – even an EV – you’re using energy and consuming goods. All of that has emissions behind it.”
In most cases, those emissions come from companies operating within New Zealand’s legal framework – following rules set out under the Emissions Trading Scheme (ETS), reporting requirements, and other regulatory obligations.
“So, it’s silly stuff to then try and sue those law-abiding companies,” Langford says.
He points out that long-lived carbon dioxide emissions are already captured under the ETS, and the Government is actively investing in research and tools to help farmers reduce their short-lived methane emissions.
“If these companies are following the rules, there has to be some certainty and protection in that, or the legal risk becomes unmanageable.”
Mooney’s Bill would provide that certainty by spelling out in law that private legal action cannot be taken against individuals or companies for their greenhouse gas emissions, provided they’re complying with climate laws already set by Parliament.
“Rather than force the courts to debate and decide what the law in New Zealand is, this Bill would allow Parliament to exert its authority and define the law,” Langford says.
He says it’s no different from how things work in other areas of law.
“If a property developer gets resource consent to build a high-rise apartment, the neighbours can’t turn around and sue them for the shade or noise.
“That’s because we recognise the developer has done everything required under the law to get permission.
“Why should climate law be treated any differently?”
Smith’s lawsuit covers major electricity generators, petrol retailers, dairy farming and dairy processing.
Langford warns that if Smith’s case is successful, it would see a host of vital industries face major cost and risk.
The case could open the floodgates to further lawsuits against other industries that also produce emissions, even if they’re fully compliant with New Zealand’s climate regulations.
“In practice, the only way for those industries to avoid legal risk would be to stop emitting entirely – meaning they’d effectively have to shut down overnight.”
He says that would be economically disastrous and would leave the Government scrambling to urgently rewrite the law to protect the economy.
“If the case is successful, Parliament will simply be forced to urgently change the law. Let’s not wait for that crisis. Parliament should clarify the law now, before this goes any further.”
Federated Farmers is urging the Government to adopt Mooney’s Bill as a Government Bill, which would significantly speed up its passage through Parliament.
“Rather than wait for Fonterra and Dairy Holdings to go through a lengthy and expensive High Court process – something that will also cost taxpayers dearly – the Government should step in now and provide certainty.
“We need to focus our time, energy and taxpayer dollars on solutions that actually reduce emissions, not on endless litigation against companies doing everything the law requires.”

Legislation – Collins admits plans to restrict the right to strike – PSA

Source: PSA

Public Service Minister Judith Collins’ admission in Parliament that the Government is looking at restricting public sector workers' fundamental right to strike is deeply concerning and demands further explanation, says the Public Service Association Te Pūkenga Here Tikanga Mahi.
In response to questions in Parliament yesterday from Camilla Belich, Collins stated the Government is “looking at how we can strengthen the bargaining system so that people might have better options available before racing off to strike, such as, for instance, mediation or any other sorts of facilitated bargaining.”
PSA National Secretary Fleur Fitzsimons says Judith Collins needs to come clean about exactly what the Government is planning, as mediation and facilitation already exist and are regularly used.
“Judith Collins admitted in Parliament that the Government is looking to further limit the right to strike. This is a very serious matter and demands an urgent explanation.
“The right to strike is a cornerstone of our democratic workplace relations system. Any attempt to restrict this fundamental right would be a direct attack on working people's ability to negotiate fair wages and conditions.
“This Government has already shown it is willing to remove basic rights without consultation when it stripped away women's pay equity rights in the dead of night. It has also already undermined the right to strike by introducing pay deductions for partial strikes.
“Collins talks about 'better options' but what she's really talking about is forcing workers into new processes that favour employers and which remove the remaining few tools workers have to push back. There are already significant limits on the right to strike in New Zealand.
“The right to withdraw labour is fundamental to the balance of power in workplace negotiations and should not be further restricted.”
The PSA is calling on Collins to rule out any further restrictions on the right to strike and to instead focus on ensuring public sector workers receive fair pay rises that keep pace with the rising cost of living.
“Public sector workers provide essential services to New Zealand and face the same cost of living pressures as everyone else. They deserve to be paid fairly and treated with respect, not have their rights stripped away,” Fitzsimons said.
The Public Service Association Te Pūkenga Here Tikanga Mahi is Aotearoa New Zealand's largest trade union, representing and supporting more than 95,000 workers across central government, state-owned enterprises, local councils, health boards and community groups.
