NZ Property Compliance
What Landlords Must Know
The Healthy Homes Standards are now fully in force for all private rentals. Non-compliance risks fines of up to $7,200. This guide explains exactly what is required — and how to stay on top of it.
Why compliance matters more than ever
The Healthy Homes Standards, introduced under the Housing Improvements Regulations 2019, set minimum standards for heating, insulation, ventilation, moisture control, and draught stopping in all residential rental properties in New Zealand.
The compliance dates have now passed for the majority of private rental properties. As of 1 July 2025, all private rentals — new and existing tenancies — must comply with all five standards. Community housing providers and Kāinga Ora have their own phased deadlines under the same regulations.
Beyond Healthy Homes, the Residential Tenancies Act 1986 (as amended) imposes additional obligations around smoke alarms, tenancy agreements, bond lodgement, inspections, rent increases, and maintenance. The Ministry of Business, Innovation & Employment (MBIE) enforces these through Tenancy Services, with fines issued for breaches.
The practical challenge for most landlords is not understanding what is required — it is tracking whether each requirement is actually met, documented, and up to date across one or more properties.
Healthy Homes Standards — explained plainly
Each standard has specific technical requirements. Here is what each one means for a typical NZ rental property.
Heating Standard
A fixed heater must be capable of heating the main living room to at least 18°C.
The heater must meet a minimum heating capacity calculated from the room size, ceiling height, and insulation level. Heat pumps are the most common compliant solution. Portable plug-in heaters do not count.
Landlord tip
Get a heating assessment from an accredited assessor if you're unsure whether your current heater meets the capacity requirement.
Insulation Standard
Ceiling and underfloor insulation must meet minimum R-value requirements and be in acceptable condition.
Insulation must be installed to the level required by the New Zealand Building Code at the time of installation, or to current requirements if being replaced. Pre-existing insulation that is damaged, wet, or compressed may not be compliant even if originally installed correctly.
Landlord tip
If your insulation was installed before 2000, it likely does not meet current requirements. Get an insulation assessment before your next tenancy starts.
Ventilation Standard
Kitchens and bathrooms must have functioning extractor fans. All habitable rooms must have openable windows.
Extractor fans must vent to the outside (not just recirculate air) and must be in working order. In kitchens, the fan must be within a metre of the cooking surface. Rangehoods count if they vent externally. Windows must be able to open a minimum of 5% of the floor area of the room.
Landlord tip
Recirculating rangehoods that do not vent to outside do not meet the standard. Replacement with an externally-venting model is required.
Moisture Ingress & Drainage Standard
Properties must have efficient drainage and — where there is underfloor access — a ground moisture barrier.
Gutters, downpipes, and drainage must all be functioning efficiently. Properties with a subfloor space accessible by a person must have a polythene ground moisture barrier covering the entire soil area. The barrier must be in good condition and properly fixed.
Landlord tip
Blocked gutters or a damaged moisture barrier are easy to miss but straightforward to fix. An annual check before winter is good practice.
Draught Stopping Standard
Unnecessary gaps and holes in walls, floors, ceilings, and around doors and windows must be blocked.
This includes gaps around pipes, chimneys not in use, and gaps under exterior doors. Gaps that are required for ventilation (such as subfloor vents) do not need to be blocked. The standard applies to gaps that allow unreasonable draughts into habitable spaces.
Landlord tip
Draught stopping is typically the lowest-cost standard to achieve and often overlooked. Check doors, skirting boards, and around pipe penetrations.
Other legal obligations under the RTA
In addition to Healthy Homes Standards, the Residential Tenancies Act requires landlords to meet these obligations or face financial penalties.
Smoke Alarms
Up to $4,000 fineWorking smoke alarms required in all rental properties. At least one on each level, within 3 metres of each bedroom door. Long-life photoelectric alarms required in new installations since 2016.
Tenancy Agreement
Up to $1,500 fineA written tenancy agreement must be provided to the tenant before or at the time they sign. Must include rent, bond, start date, and agreement type. A copy must be given to the tenant after signing.
Bond Lodgement
Up to $1,000 fineBond must be lodged with Tenancy Services within 23 working days of receiving it. The landlord cannot retain bond to cover normal maintenance or fair wear and tear.
Healthy Homes Compliance Statement
Up to $1,500 fineFrom 1 July 2019, all new or renewed tenancy agreements must include a statement of the property's current level of compliance with the Healthy Homes Standards.
Routine Inspections
Up to $2,000 if unlawful entryLandlords may inspect a property, but must give at least 48 hours' written notice (and not more than 14 days before). Inspections can only be carried out between 8am and 7pm on any day.
Rent Increases
Up to $1,500 fine for improper increasesRent can only be increased once every 12 months and must be preceded by 60 days' written notice. Any increase that is significantly above market rate can be challenged at the Tenancy Tribunal.
Fines for non-compliance
Fines are imposed by the Tenancy Tribunal. The amounts shown are maximum penalties. Tenants and advocacy groups can and do file claims — always keep documentation.
Track every compliance requirement in one place
Flathive's compliance dashboard covers all five Healthy Homes standards plus your key legal obligations. Each category has a status (Compliant, Pending Review, or Non-Compliant), document upload, notes, and a reminder date.
Requirement is met and documented. Certificate or evidence uploaded.
Needs assessment, work, or documentation. Reminder date can be set.
Actively does not meet the standard. Action required before next tenancy.
Practical steps for NZ landlords
Get a Healthy Homes assessment. An independent assessor can evaluate your property against all five standards and give you a written report. This is useful both for identifying gaps and for demonstrating compliance if challenged.
Include a compliance statement in every tenancy agreement. Since July 2019, every new or renewed tenancy agreement must include a statement of the property's compliance with the Healthy Homes Standards. This is a legal requirement, not optional.
Document everything. Compliance certificates, insulation install dates, smoke alarm test records, heating assessments — keep copies. If a tenant makes a complaint to Tenancy Services, documentation is your only defence.
Set reminder dates for recurring requirements. Smoke alarm testing, insulation inspections, and routine property checks all have a recurring element. Set reminders before they are due — not after you receive a notice.
Use a system, not a folder. Physical folders and email threads make compliance impossible to audit. Use Flathive's compliance tracker to record status, upload documents, and get reminders — all within your property dashboard.
Flathive's compliance tracker is built around the 13 most important categories for NZ rental properties — covering all five Healthy Homes standards and your core legal obligations. Access it from your property management dashboard at any time.
