Healthy Homes Standards: The 2026 Guide
The grace period is over. All private rentals must now fully comply with the 5 key standards. Landlords face fines up to $7,200 for non-compliance.
Why 2026 is Critical for Landlords
If you own a rental property in New Zealand, the “wait and see” approach is no longer an option. As of late 2025, the final compliance window for private rentals closed. Now, in 2026, Tenancy Services is actively auditing properties. The focus has shifted from education to enforcement.
The Healthy Homes Standards were introduced to ensure rental homes are warm, dry, and safe. However, many landlords are still caught out by the specific technical requirements, particularly around heating capacity calculations and draught stopping. It is not enough to just have a heater; it must meet the specific kilowatt output required for the living room size.
The 5 Standards You Must Meet
Compliance is mandatory for all private rentals, boarding houses, and KΔinga Ora houses. There are very few exemptions. To protect your investment and your tenants, you must tick off every item on this list.
- Heating Standard: The main living room must have a fixed heater (usually a heat pump) that can heat the room to at least 18Β°C. Portable heaters do not count.
- Insulation Standard: Ceiling and underfloor insulation must meet the 2008 Building Code or better. Gaps in insulation are not tolerated.
- Ventilation Standard: Living rooms, dining rooms, kitchens, and bedrooms must have openable windows. Kitchens and bathrooms MUST have extractor fans vented to the outside.
- Moisture Ingress & Drainage: Landlords must ensure efficient drainage and, if the property has an enclosed subfloor, a ground moisture barrier (polythene sheet) must be installed.
- Draught Stopping Standard: Gaps under doors or around windows that cause noticeable draughts must be blocked. Open fireplaces must be blocked unless requested otherwise by the tenant.
How to Prove Compliance
You cannot just “say” you are compliant. You need a formal compliance statement attached to every new tenancy agreement. Without this paper trail, you are already in breach of the Residential Tenancies Act.
Cost vs. Fine: The Financial Reality
Many landlords hesitate due to the upfront cost of installing a heat pump or extractor fans. However, when you compare the installation cost against the potential fines, the choice is clear.

Where Landlords Get Caught
The “Top-Up” Heater Mistake: Some landlords think a small plug-in heater in the hallway counts. It does not. The heater must be fixed (bolted to the wall) and located in the main living room.
The 120mm Fan Rule: Older bathroom fans often don’t meet the new standard. If you installed a fan before July 2019, it might be exempt, but any new fan must have a diameter of at least 120mm and vent outside (not into the ceiling cavity).
Disputes & Resources
If a dispute arises, communication is key. Landlords should keep receipts of all work done. Tenants should document issues (like mold or cold rooms) with photos.
If the landlord refuses to act, the tenant can issue a ’14-day Notice to Remedy’. If the work is still not done, the next step is the Tenancy Tribunal.
