Our history

The New Zealand Green Building Council was founded in July 2005 and in 2006 became a member of the World Green Building Council (WGBC), marking its formal recognition as a green building council under the auspices of the WGBC.

In 2006, the NZGBC was only the sixth green building council internationally. There are now approximately 100 around the world, which the WGBC classifies as either ‘established’ or ‘emerging’. Green building councils work in regional networks, and New Zealand is part of the Asia-Pacific network.

Rating tools are one of the primary ways that GBCs work to educate the market and incentivise better building practice, by giving independent endorsement to buildings that proves they have reached a level of sustainability.
