What's Required for Healthy Homes Insulation?
Since 1 July 2019, all rental homes in New Zealand must have ceiling and underfloor insulation that meets minimum R-value requirements (the level of thermal resistance). The exact values depend on where your property is located, but in most parts of the country, you'll need at least:
- Ceiling Insulation: R 2.9 or higher
- Underfloor Insulation: R 1.3 or higher
The insulation also needs to be in good condition — no gaps, no mould, and no damage. If the existing insulation is old or doesn’t meet the standard, it will need to be topped up or replaced.

Get It Sorted Early — It Pays Off
Every rental in New Zealand needs to be fully compliant by 1 July 2025. Leaving it too late means risking fines and a last-minute rush. Getting it done now means peace of mind and warmer tenants — not to mention fewer complaints in winter.
Landlords can check insulation standards using the online insulation tool at

Insulation must meet specific R-value requirements, and installation should adhere to NZS 4246:2016 standards.
