Healthy Homes Standard

Is your property compliant?

The New Zealand Healthy Homes Standards are a set of regulations designed to improve the quality of rental properties in the country. The standards set minimum requirements for heating, insulation, ventilation, moisture control and draught stopping.

The insulation standards require that all rental properties have ceiling and underfloor insulation that meets a minimum thickness (mm) and R-value (a measure of insulation effectiveness).

Ceiling insulation must be at least 120mm thick and have an R-value of at least R2.9. Underfloor insulation must be at least 70mm thick and have an R-value of at least R1.3.

The insulation must be installed safely and securely, and any gaps must be repaired.
It is a requirement that most rental properties with an enclosed subfloor have a ground moisture barrier installed.

The barrier must cover the entire ground surface of the subfloor and be made of an appropriate material, such as heavy duty polythene. The barrier must be properly installed to prevent moisture for entering the subfloor.
The heating standards requires that all rental properties have fixed heating device capable of maintaining a minimum temperature of 18ºC in the main living area.

It is best practise to use the tenancy services heating tool to determine the minimum kW of heating required. The heating device must be safe, easy to use and located in a suitable place.
