Homestar is a voluntary rating tool developed by the New Zealand Green Building Council (NZGBC). It sets a clear framework for building better homes, recognising performance in climate resilience, ecology, community impact, operational efficiency, lower embodied carbon, and improved health and comfort.

More than a checklist, Homestar provides architects, designers, and builders with a structured pathway to achieve measurable outcomes. It also rewards homeowners with an independent rating that demonstrates quality and care well above minimum Building Code compliance.

A Homestar-rated home is designed to be healthier, warmer, drier, and more comfortable, while using less energy and water than a comparable Code-minimum home.

The New Zealand Building Code establishes only the legal minimum standard. Over time, it has often been treated as a design target rather than a baseline. As a result, many homes, even new ones, fall short of international expectations for warmth, ventilation, energy performance, and long-term wellbeing.

A warm, dry home should not be aspirational, it is fundamental. Poor housing quality contributes directly to preventable health issues, including respiratory illness in children. We can, and should, build better.

Homestar certification also unlocks preferential green lending options from major banks including ASB, Westpac, and BNZ, recognising the reduced risk and long-term value of high-performing homes. More information here.

We all deserve healthy, comfortable, resilient places to live, homes that support the future of our whānau to live, work, and thrive.
