Homestar is designed to be an independent rating tool for assessing the health, efficiency, and sustainability of homes across Aotearoa.

Since launching Homestar in 2010, we continue to work with experts and organisations across industry and government to ensure it supports New Zealanders in the design, construction and liveability of resilient homes for the long term.

Homestar is a holistic tool that to rate a home’s performance and environmental impact. A 10 Homestar rating recognises world leading standards for design, construction and efficiency in operation. A 6 Homestar rating recognises a home that has been built at or above the current standards set by the New Zealand building code, dependent on location across Aotearoa.

Homestar is currently in its fourth edition, with version five launching in 2021.
