The Homestar rating system developed by a joint venture between the New Zealand Green Building Council and BRANZ, is supported by EECA and industry partners. It aims to improve the standard of Kiwi homes by providing a comparison against a benchmark from 1-10 stars. This means homeowners can work towards making their homes warmer, healthier and more energy efficient – so reducing their environmental impact, and enhancing liveability and efficiency of the home.

Homestar provides independent advice and guidance on the health and energy performance improvements to the home, as well as professional design and construction services for new builds and renovations.

Homestar has been developed to take into account regional building standards. You can do your own self-assessment using an online home-evaluation report when you become a member of Homestar. Or you can pay about $800 to have a formal assessment done by a Homestar professional, which results in a certified rating.

Become a FREE member of myHomestar to use the self-assessment rating and receive a customised report to help you decide how to prioritise maintenance and renovation work to make your home healthier, warmer and more comfortable. You will also receive fortnightly newsletters about the latest in sustainability and access Partner offers.
