Homestar - Nzgbc

Homestar has been designed to make sure that Kiwi homes are healthy, warm, dry places for New Zealanders to enjoy. 

A home is rated on a 6-10 scale.  A 10 Homestar rating means you’ve built a world leading home. Most existing New Zealand homes would only achieve a 2-3 Homestar rating on the scale. A new home built only to Building Code would achieve 3-4 Homestar on the scale.

If your home is already underway, and you want to make sure it’s going to be healthy and warm by using Homestar, then you should get in contact with a Homestar assessor as soon as you can.
It’s much better, and easier, to start using Homestar early in the process, ideally before the design of your home has started.
