Homestar was developed from successful international rating tools and adapted for New Zealand’s specific conditions. It can be used on any residential building, from stand-alone homes to multi-unit dwellings. Homestar is a comprehensive, independent national rating tool that measures the health, warmth and efficiency of New Zealand houses. A home is rated on a scale from 6 to 10. A 6 homestar rating or higher provides assurance that a house will be better quality - warmer, drier, healthier and cost less to run - than a typical new house built to building code. A 10 homestar rating means you've built a world leading house
