When you choose roofing, you’re not just picking a colour or profile, you’re deciding whose work and values sit over your head. Genuine Colorsteel isn’t just about looks or performance. It’s about where it comes from, who makes it, and what that means for your home and your community.
Paul Aldolphe, Business Development Manager at New Zealand Steel, says many homeowners don’t realise that Colorsteel is made right here in New Zealand. “A lot of Kiwis aren’t aware we have a very innovative process of making steel locally,” he explains. That local story carries weight for more reasons than one.
Made in Glenbrook, supporting Kiwi jobs
New Zealand Steel’s Glenbrook mill in South Auckland has been producing steel since the 1960s. Today it employs around 1,400 people directly and supports another 2,400 indirectly. At a time when global supply chains are under strain, buying local means more than just convenience. It reduces delays, ensures product traceability, and gives homeowners confidence that they are investing in something built to last.
A fully integrated process
One of the things that makes Glenbrook unusual is its “all-in-one” approach. From refining New Zealand iron sands to applying the protective coatings and paints, every step happens on site. This integrated process is rare worldwide and ensures quality is controlled from start to finish. That also means better consistency for homeowners. When you choose genuine Colorsteel, you’re not just buying a roof profile. You’re getting a material with a known grade, a backed warranty, and the assurance of local aftercare should anything ever need attention.
Innovation for New Zealand conditions
New Zealand’s environment is tough on buildings, with salty coastal air, geothermal zones, and high-humidity areas. Colorsteel is part of BlueScope, a wider Australasian steel group that invests heavily in research and testing. Across the region, more than 20,000 test panels are monitored in real-world conditions. From magnesium-infused alloys that slow corrosion to matte finishes that resist glare and oil-canning, every improvement is tested before it reaches the market. The result is a roof designed to handle local conditions and backed with performance data.
A push for sustainability
Looking ahead, New Zealand Steel is investing in reducing its carbon footprint, with technologies like hydrogen input and an electric arc furnace. These steps are part of a wider commitment to support builders and homeowners aiming for Homestar or Green Star ratings. Choosing locally made Colorsteel isn’t just practical. It’s a way of investing in more sustainable building practices for the future.

Episode Overview
In this episode of the Trends Property Insight Series, we sit down with Haydon Rogers, Category Manager at Altus Window Systems, to explore the often-overlooked role that windows and doors play in the comfort, performance, and visual identity of your home. From ranch sliders to high-performance glazing, Haydon walks us through the key decisions homeowners face when renovating or building, including how to balance aesthetics, ventilation, thermal efficiency, security, and cost. He explains why joinery isn’t just a finishing detail, but a crucial part of your building envelope that affects everything from heating bills to natural light, acoustic control, and resale appeal.
