Defence News – Hercules lights up Cook Islands Blue Light course
For the first time in its more than 10-year history, the Cook Islands Blue Light programme has given its teenage participants a hands-on experience with a multi-million-dollar Royal New Zealand Air Force (RNZAF) C-130J Hercules aircraft.
The 27 young Cook Islanders were given a tour of the RNZAF’s newest aircraft last week when it overnighted at Rarotonga Airport as part of its work for Exercise Tropic Twilight on Ma’uke.
“This is the first we’ve been able to take the Cook Islands Blue Light group through a Hercules. It has taken a lot of planning but it’s been worth it,” said Sergeant Ryan Merwood.
“The kids loved the aircraft. They were raving about it all day. They wanted to get through the cockpit and take all the photos, basically to get an experience of the Air Force.”
It was a taste of one end of military life during the five-day course which relies a lot on the basics of military training normally given to new recruits.
It is run by Cook Island Police, Blue Light NZ, and with help from three instructors from the New Zealand Defence Force’s (NZDF) Youth Development Unit.
Tuakeu Paerau, 18, who is in his last year at school and thinking of joining the police, said he loved the course.
“My favourite part is listening to the staff and doing what we are told. We get more rewards out of that.
“I also enjoy the marching and drills. We are proud of ourselves when we march. We march like we are actually in the military, thanks to the training.”
Tiare Williams, 17, is now thinking about joining the Army after her parents got her involved with Blue Light.
Already active and into sports, she said she enjoyed the marching, waking up early and runs.
She also appreciated what she had learned around teamwork, communication and discipline.
“The NZ Army soldiers are pretty cool. They are straight to the point and don’t muck around.”
The course covered a range of skills, from basic cooking, tying knots, rules around driving, cyber safety and setting goals to the fun of games and even a lagoon cruise – a tourist trip many might not normally experience.
“We provide the good leadership-style activities, as well as drill and marching, waking up early and making themselves clean and presentable,” Sergeant Merwood said.
The teens generally picked up marching and drill quickly.
“At first, it’s a bit foreign to them. They struggle with the idea of drill with uniformed personnel barking orders. Come Day 2 it’s completely normal, big smiles, they want to show off and be the best.
“Just in two days I was telling them they should be extremely proud. They could march, left and right turn, about turn and do drill movements that a lot of our soldiers might take a little while to get the hang of.”
Putting smiles on the teens’ faces was why many YDU staff did the job, Sergeant Merwood said.
“And when you end up seeing them in uniform, it is a very fulfilling moment.
“We are incredibly proud to be here working with amazing kids, and growing the partnerships we have with Cook Islands Police and Blue Light NZ. It’s extremely rewarding.”
Senior Sergeant Epii Poila said Blue Light started in the Cook Islands in 2014 as a response to problems around truancy.
Those issues with at-risk youth had since declined, and now the programme was good for building confidence, offering structure and career pathways, he said.
The NZDF component helped bring structure and discipline to the students and previous participants had since become police officers or joined the NZDF, he said.
“Our youth here love anything to do with the Defence Force. It focuses their attention and it’s so different for them.”

Universities – Discovery of new marine sponges a ‘huge surprise’ – VIC
A research team exploring marine sponges in Fiordland has found half of the 82 sponge specimens collected during a recent trip are new to science.
The discovery of so many new species was “a huge surprise” and exceeded all expectations, said Professor James Bell, a marine biologist at Te Herenga Waka—Victoria University of Wellington and leader of the research team.
“We set out expecting we might find a few new species—if we were lucky. We had no idea of how many different sponges the fiords hold. It seems crazy because we dive so much there, but we have just been swimming past all these beautiful, undescribed sponges,” said Professor Bell.
Sponges play a vital role in the marine environment, recycling nutrients and forming “sponge gardens” that provide habitat for fish and other species.
Dr Michelle Kelly, a sponge taxonomist specialist at Earth Sciences New Zealand, confirmed 41 of the sponge species collected in Fiordland were undescribed and have yet to be named. They add to the approximately 1,700 sponge species already known to live in waters around Aotearoa New Zealand.
The sponges were collected during a research trip in April to investigate the distribution of these animals in Fiordland and how it differs between the inner and outer parts of the fiords. Back in the lab, the sponge specimens were compared with samples of known species held in a collection at Earth Sciences New Zealand.
Dr Kelly described the study of taxonomy—identifying, naming, and describing species—as “like a good Agatha Christie novel, putting all the clues together to get an answer”. Finding new and undescribed species was “very exciting, although not unexpected give the sheer abundance of sponges on the vertical walls of the fiords and the lack of previous formal research on Fiordland sponges,” she said.
Sponge identification starts by creating “spicule preparations”, where sponge tissues are dissolved to reveal the calcium carbonate and silica spicules—tiny parts of the sponge skeleton. These spicules are used along with other characteristics—including shape, colour, texture, mucus production, and even smell—to classify different species.
Dr Francesca Strano, a post-doctoral research fellow at Te Herenga Waka who worked with Dr Kelly, said identifying and describing the new species was crucial for effectively managing and conserving Fiordland’s marine ecosystems, and tracking changes in the environment.
“Species identification takes a lot of time but is really important for managing our oceans, particularly when there is still so much biodiversity we have yet to discover, often just under our noses,” said Dr Strano.
The study is one of the projects of the Southern Fiordland Initiative, a research collaboration aiming to find out more about the marine environment in the fiords and how it is changing. The George Mason Charitable Trust and Te Herenga Waka provided funding for the research.
Property and Construction – Construction costs have surged almost twice as fast as inflation over the past decade
New Zealand’s residential construction costs have risen around 61% since 2015, compared with a 33% rise in the Consumers Price Index (CPI) — highlighting how building costs have surged ahead of everyday prices.
The data, drawn from QV CostBuilder, New Zealand’s largest subscription-based construction-cost platform, shows that building-cost inflation has run at roughly 1.8 times the pace of general inflation over the past ten years.
“Over the past decade, our data shows the cost of building a standard 175m² home rose 61%, compared with a 33% rise in general consumer prices,” said QV CostBuilder Quantity Surveyor Martin Bisset. “That’s a 28-percentage-point gap — building-cost inflation has been running well over one and a half times the pace of overall inflation.”
Since its launch in 2015, QV CostBuilder has provided those working in the construction industry including builders, quantity surveyors, valuers, architects, students and councils, with trusted data to help price and plan projects. The platform now tracks more than 61,000 rates and 18,000+ material and installer prices nationwide, updated monthly.
Mr Bisset said that while the last decade included dramatic spikes — particularly through 2021–2022 when global supply chains were disrupted and material costs soared — more recent years have brought greater stability. “We’ve seen the cost of construction flatten out since 2023, with annual increases back down around 1% in 2025,” he said.
Some materials have risen far faster than the average. Cedar weatherboards recorded the greatest increase tracked by QV CostBuilder, rising from $17 per metre in 2015 to a high of $64 in 2022, before easing back to $53 today. Shadowclad exterior plywood is up 110%, windows 72%, and steel sheet roofing 76%. Radiata pine clear flooring climbed 122%, carpet 41%, ready-mix concrete 43%, and Radiata pine framing 45%. Plywood saw one of the lowest rises, up just 12%. Construction labour costs increased slightly higher than CPI, up about 35%.
Non-residential buildings (excluding educational) rose 42% over the decade — quite a bit less than residential increases.
“There’s no doubt the past decade has been one of the most extraordinary periods for New Zealand’s construction industry,” said Mr Bisset. “QV CostBuilder’s consistent data has helped professionals benchmark costs and plan with greater confidence through some very challenging years.”
Many salaries in New Zealand have also failed to keep pace with inflation, rising much less than 33% over the past decade, making the affordability challenge even more pronounced for those wanting to build homes.
Over the past ten years, 439,000 individual costs have been updated within QV CostBuilder, helping subscribers save thousands of hours of research time. The platform delivers reliable, data-driven insights, providing ten years of support and 0% guesswork for construction professionals who rely on it to cost and plan projects with precision.
Since its launch, QV CostBuilder has continued to evolve — with new tools like Pick Lists for customised rate downloads, and close supplier engagement to keep data current and credible. As the construction sector looks to the next decade, QV CostBuilder continues to expand— providing the trusted foundation professionals need to plan, price, and build smarter.
QV CostBuilder is powered by state-owned enterprise Quotable Value (QV) and remains New Zealand’s most comprehensive subscription-based building-cost platform, covering everything from square-metre rates for homes, schools, and offices to material and labour pricing.
Mr Bisset added that to celebrate 10 years of QV CostBuilder, the company is offering $50* off new subscriptions for those who sign up by 14 November 2025 using the promo code COUNT-ME-IN. Go to costbuilder.qv.co.nz for more details.
