All new refrigerators, freezers, heat pumps, clothes washers, clothes dryers, dishwashers, televisions and computer monitors available for sale in New Zealand must display the Energy Rating Label, which shows how much energy a product uses per year. The rating system is based on stars: the more stars a product has, the more efficient is it, up to a maximum of six stars.

The stars can be used to compare products that are the same size and have the same function, however the energy consumption figure shows a per annum energy use that can also be used to compare products of a different sizes.

In New Zealand, the Energy Rating Label is run by the Energy Efficiency and Conservation Authority (EECA).

HomeFit is a straightforward way to check the quality of a home – that it’s warm, safe and dry.

A HomeFit home has been certified to be fit for living. This means the home includes features that make it warm, safe and dry, and more efficient to run. It’s an assessment of health, comfort, energy efficiency
and safety, and covers a range of criteria that are essential for a home to be liveable.

HomeFit also includes a higher standard called HomeFit PLUS, for a home that is even warmer, drier, more comfortable and energy efficient. HomeFit Plus homes have more insulation, more energy efficient lights, energy efficient heating and hot water.

If you get a home HomeFit certified, it will also meet the Healthy Homes Standards.

HomeFit is run by the New Zealand Green Building Council.


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 new home built only to Building Code would achieve 3-4 Homestar on the scale. A 6 Homestar rating or higher provides assurance that a house will be warmer, drier, healthier and cost less to run than a typical new house built to the building code. A 10 Homestar rating means you’ve built a world leading home.

At 6 Homestar you’ll notice a real difference in warmth, dryness, health and water efficiency. That’s because it’s certified as having better levels of insulation than Building Code requires, moisture-control measures, and water-efficiency measures such as dual flush toilets and low-flow showers.

Homestar is run by the New Zealand Green Building Council.
