The Department of Conservation was launched in 1987 and tasked with managing, and protecting, the country’s natural and historical heritage.These important national treasures included natural heritage, recreation facilities, and the coastal marine environment. Because DOC is responsible for the entire country it sometimes requires innovative ways to move people – and wildlife – to far-flung places. Often this leads to truly ‘uplifting’ ideas designed to achieve maximum coverage for minimum cost.

A housing solution that really took off When the Department needed to mobilise forces for a major undertaking on a number of Fiordland islands they were forced to think outside the box.

The plan was to rid these islands – which had been labelled ‘restoration islands’ – of pests and predators, thus protecting the native plants and species already in residence. Once this ‘beachhead’ was established the second phase was to provide a safe and secure haven for many of New Zealand’s more threatened species, including the Saddleback and the Kiwi.

The most ambitious island re-claiming project took place on Resolution Island. The staff at DOC’s Te Anau office took on the challenge of finding the best way to house the ‘troops’ who would take part in the project. These included track cutters, stoat trappers and deer hunters who would all be involved in the battle to restore the island.

The solution came in the creation of 13 ‘flyable’ huts that would be helicoptered into place and then flown out once the job was completed. The building material of choice was New Zealand steel’s own COLORSTEEL® ENDURA® (for the roofing and cladding) and AXXIS® (steel for framing) products.

As the project evolved a number of enhancements were made. This included a reduction in the steel required for framing, including the built-in bracing. The flexibility of building with steel allowed these to be made with little disruption. The end product was a lighter, stronger and cheaper building.

Not only could the hut be airlifted, but so could its associated timber framed annexe. Originally these two units needed to be flown separately but the new solution reduced the number of flying hours required and made it a breeze to install, and handle, each unit on site.

Material: Colorsteel Endura® in Karaka

Our story started over 40 years ago when New Zealand Steel began making COLORSTEEL® roof and wall cladding products from New Zealand iron sand. It was a world first, and a feat that required imagination, ingenuity and sheer determination. 

These qualities have become COLORSTEEL® pillars - it’s who we are and how we work. 

For New Zealand:
We’re inspired by the landscape around us. From snow topped mountains to tussock grasslands, you’ll see New Zealand reflected in everything we create.

COLORSTEEL® products also undergo intense, long-term colour performance and exposure testing. So you can be sure they’re made and trusted for our conditions. We’re so confident in the durability of our products, we back them with robust warranties.

For you:
We’ve developed COLORSTEEL® products to meet the needs of New Zealanders. Whether it’s roofing your dream home, building a fence or cladding a warehouse– there’s a COLORSTEEL® solution for your project.

By combining beauty, durability and flexibility, we believe COLORSTEEL® is about more than just a steel solution - it’s about turning metal into magic and transforming the everyday.

For the environment:
All COLORSTEEL® solutions carry the Environmental Choice NZ licence which means they can contribute to the achievement of maximum points in Homestar and Green Star materials credits with NZ Green Building Council.
