NZ Healthy Homes Standards: A Landlord's Compliance Guide (2026)
Complete guide to New Zealand's Healthy Homes Standards for landlords. Covers heating, insulation, ventilation, moisture, and draught stopping requirements, deadlines, and penalties.
The Healthy Homes Standards are a set of legally enforceable minimum requirements for New Zealand rental properties, introduced under the Residential Tenancies (Healthy Homes Standards) Regulations 2019. They set specific standards for heating, insulation, ventilation, moisture ingress and drainage, and draught stopping that all private landlords must meet.
What Are the Healthy Homes Standards?
The standards apply to all private residential tenancies, boarding house tenancies, and some social housing tenancies. They are legally enforceable — landlords who fail to comply face penalties and potential Tenancy Tribunal orders.
According to Tenancy Services NZ, landlords must include a Healthy Homes compliance statement with every new or renewed tenancy agreement, confirming whether the property meets each of the five standards.

The Five Standards at a Glance
| Standard | Core Requirement | Key Metric |
|---|---|---|
| Heating | Fixed heater in main living room | Must heat to at least 18°C |
| Insulation | Ceiling and underfloor insulation | Minimum R-values by climate zone |
| Ventilation | Openable windows + extractor fans | 5% of floor area for windows |
| Moisture | Adequate drainage + ground vapour barrier | No unreasonable moisture ingress |
| Draught stopping | Seal unnecessary gaps and holes | Windows/doors close properly |
The Five Standards Explained
1. Heating Standard
Every New Zealand rental property must have a fixed heater in the main living room capable of heating the room to at least 18°C. Qualifying heater types include heat pumps, wood burners or pellet burners (meeting NES requirements), and flued gas heaters. Portable electric heaters, unflued gas heaters, and open fires do not meet the standard.
Electric panel heaters only qualify if the living room is small enough — under 12m². For most properties, a heat pump is the most cost-effective compliant option.
2. Insulation Standard
Ceiling and underfloor insulation must meet minimum R-values or be in reasonable condition if it was installed when building consent was issued. The requirements vary by climate zone:
| Climate Zone | Regions | Ceiling R-value | Underfloor R-value |
|---|---|---|---|
| Zone 1 | Auckland, Northland | R 2.9 | R 1.3 |
| Zone 2 | Waikato, Bay of Plenty, Wellington | R 2.9 | R 1.3 |
| Zone 3 | Canterbury, Otago, Southland | R 3.3 | R 1.3 |

Existing insulation that was compliant when installed can remain if it’s in reasonable condition — meaning it’s dry, not significantly compressed, and covers the required area.
3. Ventilation Standard
Under the Healthy Homes ventilation standard, all habitable rooms must have openable windows or doors with an area of at least 5% of the floor area. All kitchens and bathrooms must have an extractor fan ducted to the outside. Fans must be in good working order.
4. Moisture Ingress and Drainage Standard
The property must have:
- Adequate drainage for the removal of stormwater, surface water, and ground water
- A ground vapour barrier if the property has an enclosed subfloor space
- No unreasonable moisture ingress — gutters, downpipes, and drains must be in good repair
5. Draught Stopping Standard
All unnecessary gaps and holes in walls, ceilings, windows, floors, and doors that cause noticeable draughts must be stopped. This includes:
- Windows and doors must close properly and have no visible gaps
- Unused chimneys and fireplaces must be blocked
- Holes around pipes and fittings must be sealed
Compliance Deadlines
For new or renewed tenancies (signed or renewed after 1 July 2021), landlords must comply within 90 days of the tenancy start date. For existing tenancies, all private landlords were required to comply by 1 July 2025. Landlords who have not yet brought their properties into compliance are already past the deadline and should act immediately.

Penalties for Non-Compliance
Key Takeaway
The Tenancy Tribunal can order landlords to carry out remediation work and can award exemplary damages of up to $7,200 for each breach of the Healthy Homes Standards. Tenants can also apply for rent reduction while standards are not met. Repeated or intentional non-compliance can result in higher penalties.

How to Stay Compliant
1. Get a Healthy Homes Assessment
Hire a qualified assessor to inspect each rental property against all five standards. The assessment will identify gaps and recommend specific remediation work.
2. Track Compliance Documents
For each property, maintain records of:
- The Healthy Homes compliance statement (provided with every new tenancy agreement)
- Assessment reports from qualified assessors
- Receipts and certificates for remediation work (heat pump installation, insulation, extractor fans)
- Photographs documenting compliance
For a complete list of compliance-related document types, see our NZ property document types guide.
3. Monitor Ongoing Compliance
Compliance isn’t a one-time event. You need to ensure:
- Heating systems remain operational
- Insulation stays in reasonable condition
- Ventilation fans continue working
- Drainage remains effective
- Draught stopping measures remain intact
Regular inspections (at least annually) should include checks against the Healthy Homes Standards.
4. Use Document Management Tools
Managing compliance documents across multiple properties is where most landlords struggle. AI-powered document management can:
- Upload assessment reports and compliance certificates
- Automatically track compliance dates and deadlines
- Search across all properties for compliance status
- Get alerts when re-assessment is due
ProppiAI automates this process — upload your Healthy Homes assessments and compliance certificates, and the AI extracts deadlines, tracks status across your portfolio, and alerts you when action is needed.

Summary
Key Takeaway
The Healthy Homes Standards require NZ landlords to meet specific requirements across five areas: heating (18°C minimum), insulation (R-values by climate zone), ventilation (5% floor area + extractor fans), moisture control (drainage + vapour barriers), and draught stopping. All private landlords must already be compliant. Non-compliance carries penalties of up to $7,200 per breach.
For landlords managing multiple properties, organised document management is essential to staying on top of compliance across your portfolio.

Thinking About Investing in Australia Too?
Australia has no national equivalent of the Healthy Homes Standards — instead, minimum standards are set state by state, with diverging rules in Victoria, Queensland, New South Wales, and the rest. Our New Zealand vs Australia property investment comparison covers hidden costs, tax differences, and why Healthy Homes is one of the things that makes NZ investing genuinely different.
