The Healthy Homes Standards set minimum requirements for rental properties in New Zealand, covering things like heating, insulation, ventilation, moisture and drainage, and draught stopping. Compliance is a legal requirement, not optional extra polish.
What the standards broadly cover
In general terms: a fixed heater capable of adequately heating the main living area, ceiling and underfloor insulation meeting current requirements, extractor fans in bathrooms and kitchens, ways for water to drain away from the property, and draught-stopping around doors, windows and other gaps.
The exact technical thresholds (heater sizing calculations, specific insulation ratings and so on) are detailed and worth getting properly assessed rather than estimated — this is general orientation, not a compliance checklist to work from directly.
Quick tip
Get a proper Healthy Homes assessment done before you list a property for rent, not after a tenant raises it or a complaint is made. It's far cheaper and less stressful to get ahead of it.
Why it's worth taking seriously beyond compliance
A warm, dry, well-ventilated home is simply easier to keep tenanted, attracts a wider range of good tenants, and reduces the maintenance issues that come from damp and mould over time. It's one of those rare cases where the compliance requirement and the sound business decision point the same direction.
Where to get the real answers
Tenancy Services (part of MBIE) publishes the official, current requirements, and a qualified Healthy Homes assessor can tell you exactly where a specific property stands. Both are more reliable than any general page, including this one.

This is general orientation only, not compliance advice. Confirm current Healthy Homes requirements with Tenancy Services or a qualified assessor.
