Welcome to the first episode of Build Aotearoa for 2026.
Coming up this year, the NZGBC will be celebrating 20 years of advocating for better buildings in New Zealand. The update of the update of H1 is bedding in, but many builders are turning their attention to roof condensation and overheating. And the market seems to be in a prolonged period of 'cautious optimism'. -
In this episode, I continue my coverage of the THRIVE 25 Conference with a series of interviews from the trade show floor. I spoke with leading suppliers whose products and innovations are helping shape the future of Passive House construction in Australasia. From high-performance windows to advanced ventilation systems, each guest shares their unique contribution to better building.

99 Waiwai Drive, Milldale north of Auckland looks like a regular new house in a regular new subdivision, but around 30 people visited the site mid-build to see why it's different. This showhome will be one of the Platinum Homes high-performance range. It's a SIP (structural insulation panel) construction and achieved a near Passive House level of airtightness.
I caught up with Sam Watt, the General Manager of Platinum Homes, Rodney.

The New Zealand Building Code does not guarantee performance in all areas that many homeowners might expect.
Fortunately, Homestar is available to close the performance gaps. -
While researching for a recent presentation at the NZGBC Housing Summit 2024, I looked into what's going on concerning climate change commitments and investment in Europe and the US.
Then I compared our progress here in Aotearoa. -
This week I attended a BRANZ seminar titled 'Building for our changing climate'. Tāmaki Makaurau Auckland was the last stop on the BRANZ seminar tour of the country and it's encouraging to think that rooms of designers, builders, product suppliers, building officials and others, were interested enough in this topic to take four hours out of their week.
A key takeaway is that we're not prepared. We're already handicapped by having insufficient standards in our building code to deal with our current climate. With the forecast being 'warmer and wetter', the situation is set to get worse.
