As of 1 July 2025, every private rental property in New Zealand must meet the Healthy Homes Standards. Originally introduced in 2019, these regulations aim to raise the quality of rental housing and reduce health risks from cold, damp, and poorly maintained homes.
If you’re a landlord, here’s what full compliance now legally requires—and what’s at stake if you fall short.
There are five core standards that all rental homes must meet:
A fixed heating device must be installed in the main living area that can heat the room to the minimum heating capacity required by the new law. This usually means a heat pump, wood burner or flued gas heater —portable devices don’t qualify.

Ceiling and underfloor insulation must meet the 2008 Building Code or if it is a newly built home then the insulation will likely meet the updated 2021 Building Code insulation requirements. The Healthy Home Standards splits New Zealand into 3 climate zones and there are requirements for each zone. Top-up insulation is required if existing materials no longer meet these minimums.
