Healthy Homes Standards for Rental Properties in New Zealand
Landlords and property managers need practical visibility before tenant complaints, tenancy changes, property management handover, rental listing, or purchasing a rental investment property.
The Healthy Homes Standards are minimum standards for rental properties and cover heating, insulation, ventilation, moisture ingress and drainage, and draught stopping. Rental properties generally need to comply unless an exemption applies. For official rule details, refer to Tenancy Services Healthy Homes guidance.
Government websites explain the rules. Cozy Building Compliance explains what those rules look like in a real Auckland rental property: visible issues, access limitations, practical repair priorities and areas where specialist confirmation may be needed.

Practical Healthy Homes Inspection Checklist
Ventilation and Extractor Fans
Ventilation is a common Healthy Homes risk area. In practical terms, we look for working openable windows and doors, extractor fans in bathroom and kitchen areas, and whether fan ducting appears to discharge moisture outside rather than into a roof space.
- Bathroom fan present but not ducted outside
- Kitchen rangehood missing or ineffective
- Extractor fan ducting disconnected in roof space
- Openable windows that do not stay fixed open
Moisture Ingress, Drainage and Ground Moisture Barrier
Moisture and drainage issues often start outside the house. We check visible gutters, downpipes, surface water direction, subfloor conditions and whether an enclosed subfloor may require a ground moisture barrier.
- Blocked gutters or poorly connected downpipes
- Surface water falling toward the house
- Damp enclosed subfloor
- Missing or damaged ground moisture barrier
Read the ground moisture barrier guide and moisture and drainage issues guide.
Draught Stopping
Draught stopping is checked visually for unreasonable gaps or holes that may cause noticeable draughts. Common areas include external doors, window joinery, floor penetrations, ceiling penetrations and unused openings.
- Gaps around external doors
- Damaged or missing seals
- Holes through floors, walls or ceilings
- Unused fireplace or opening not properly blocked

The Healthy Homes Standards are minimum standards for rental properties in New Zealand. They cover heating, insulation, ventilation, moisture ingress and drainage, and draught stopping.
Do all rental properties need to meet the Healthy Homes Standards?
Rental properties generally need to comply with the Healthy Homes Standards unless an exemption applies. The exact requirement can depend on the property, tenancy situation and supporting documentation.
What are common Healthy Homes issues in Auckland rental properties?
Common issues include bathroom fans not ducted outside, missing or ineffective kitchen extraction, blocked gutters, poor surface drainage, damp subfloor areas, missing ground moisture barriers, old insulation and draught gaps around doors or windows.
Do bathroom and kitchen fans need to vent outside?
Bathroom and kitchen extractor fans generally need to remove moisture to the outside, or the property needs another qualifying ventilation system. Fans discharging into roof spaces are a common issue that should be checked.
