Climate Zone Boundaries
There are six climate zones. The climate zone boundaries are based on climatic data
taking into consideration territorial authority boundaries.
On the 1st May 2023 NZ Government changed Climate Zones, for all building insulation requirements.
From the 1st November 2023 ALL Building Consent applications lodged must have
thermally broken window frames with Argon Gas and Low E glass, which is a significant price increase.
Also, contact us for additional costs if you are in a sea spray zone.
