Homestar
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 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 above the current standards set by the New Zealand building code.
Get involved. Find an assessor, or contact the Homestar team at the NZGBC.
Homestar version five is now available. There will be a transition period during which projects may be registered under either version four or five. This will finish on 30 June 2022 after which all projects must be registered under version five.
