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.

Homestar v5
Homestar v5 is now available and we encourage you to register projects for v5.
Homestar v5 offers a new operational energy and carbon modelling tool with targets aligned to MBIE’s Building for Climate Change framework. Combined with updated requirements to ensure a healthy, comfortable indoor environment and, for the first time also accounting for embodied carbon, achieving a minimum 6 Homestar rating under version 5 will be a significant statement of industry leadership for those choosing to be ahead of the building code.
The transition period between Homestar v4.1 and Homestar v5 will end on 31 January 2023.
From 1 February 2023 all new general Homestar registrations will be for Homestar v5.
