Healthy Homes Standards NZ: Auckland Landlord Checklist
Quick answer: New Zealand’s Healthy Homes Standards require all private rental properties to meet minimum requirements across five areas — heating, insulation, ventilation, moisture ingress and drainage, and draught stopping. Compliance deadlines for most private tenancies have already passed. Non-compliant landlords risk Tenancy Tribunal penalties of up to $7,200 per breach.
The Healthy Homes Standards aren’t a grey area. The deadlines have passed for the overwhelming majority of Auckland rental properties, the compliance requirements are specific and measurable, and Tenancy Services has been actively enforcing them.
If you’re a landlord and you haven’t done a formal Healthy Homes assessment on your rental property, you’re exposed. Not theoretically — actually. A tenant can raise a compliance complaint, Tenancy Services can conduct an inspection, and the Tribunal can issue remediation orders and exemplary damages.
This article gives you a practical checklist covering all five Healthy Homes Standards, the exact thresholds that apply in Auckland, and what to do if your property doesn’t currently meet them.
Healthy Homes compliance note: Under the Residential Tenancies Act 1986 (as amended), landlords must include a signed statement of Healthy Homes compliance in any new or renewed tenancy agreement. For private landlords, all rental properties were required to comply with all five standards by 1 July 2025. See tenancy.govt.nz for current requirements and deadlines.
The Five Healthy Homes Standards — Auckland Landlord Checklist
Work through each standard below. Each section identifies what’s required, the specific thresholds, and common compliance failures we see in Auckland rental properties.
Standard 1: Heating
What’s Required
The rental property must have a fixed heater in the main living room capable of heating that room to at least 18°C, calculated against the specific heating capacity requirements for that room’s size. The required heating capacity is calculated using a formula that takes into account the room’s floor area, ceiling height, number of external walls and windows, and the climate zone of the property.
Auckland is in Climate Zone 1. The required heating capacity for a typical Auckland living room (25m², standard ceiling height, two exterior walls) is approximately 1.5–2.5 kW. Tenancy Services provides an online heating assessment tool to calculate the exact requirement for any room.
What Qualifies
| Heater Type | Compliant? | Notes |
|---|---|---|
| Heat pump (fixed) | ✅ Yes | Must meet capacity requirement for room size |
| Wood burner / pellet fire | ✅ Yes (if fixed) | Must meet capacity; smoke control restrictions apply in Auckland |
| Flued gas heater (fixed) | ✅ Yes | Must be fixed — not a portable gas heater |
| Electric panel heater (fixed) | ✅ Yes | Must be hardwired and meet capacity |
| Portable electric heater | ❌ No | Not compliant — must be fixed |
| Unflued gas heater | ❌ No | Not compliant |
| Underfloor heating (electric) | ✅ Yes | If fixed and meets capacity calculation |
The most common compliant solution for Auckland landlords is a heat pump — cost-effective to run, easy to install, and unambiguously compliant provided the capacity matches the room. Heat pump installation for a typical Auckland living room typically costs $1,800–$3,500 supply and install.
Healthy Homes compliance note: The heating standard applies to the main living room only — not every room in the property. However, if the living room does not have a compliant fixed heater, providing portable heaters does not satisfy the requirement. See the Healthy Homes heating standard for full details.
Standard 2: Insulation
What’s Required
Ceiling and underfloor insulation must be present, in reasonable condition, and meet minimum R-value requirements based on when it was installed and the climate zone.
For Auckland (Climate Zone 1):
- Ceiling insulation: R-value of 2.9 for new insulation installed after July 2016; R-value of 1.3 or more is acceptable for existing insulation installed before July 2016 if it is in reasonable condition
- Underfloor insulation: R-value of 1.3 — applies to all properties where underfloor access exists and installation is reasonably practicable
Wall insulation is not currently required under the Healthy Homes Standards, though it may be required under building consent conditions for new builds or significant alterations.
Common Failure Points
The most common insulation failures we see in Auckland rental properties are degraded or displaced underfloor insulation and missing ceiling insulation in roof spaces that were inaccessible or overlooked.
Underfloor insulation in older Auckland homes — particularly timber-framed homes in Mangere, Papatoetoe, and Henderson — is frequently missing entirely, or was installed and has since fallen away from the joists. A visual inspection from the underfloor access point will confirm this. If the insulation is foil-based (common in older NZ homes), note that foil insulation does not meet the R-value requirements for the Healthy Homes Standards and will need to be replaced or supplemented.
💡 Property tip: Insulation installation costs for Auckland rental properties typically run $1,500–$3,500 for ceiling and underfloor together, depending on property size and access. EECA’s Warmer Kiwi Homes programme provides subsidies for eligible properties — check eeca.govt.nz for current eligibility criteria.
Standard 3: Ventilation
What’s Required
The ventilation standard has two components: openable windows in habitable rooms, and extractor fans in kitchens and bathrooms.
Openable windows: Each habitable room must have openable windows, skylights, or doors to the outside. The openable area must be at least 5% of the floor area of the room. This requirement is met by most existing Auckland homes and rarely requires remedial work.
Extractor fans: This is where most Auckland rental properties fall short.
- Kitchen: A rangehood or extractor fan must be fitted and must extract to the outside (not recirculate). If the kitchen has a cooking area, it must have an extraction device above it.
- Bathrooms and separate toilets: Each must have an extractor fan with a minimum flow rate of 25 litres per second (l/s), or meet the continuous ventilation rate standard. The fan must extract to outside the building.
A recirculating rangehood — one that filters and returns air into the kitchen rather than venting it outside — does not comply. This is one of the most commonly misunderstood requirements. Many Auckland rentals have recirculating rangehoods installed, and landlords assume they are compliant. They are not.
| Location | Requirement | Common Failure |
|---|---|---|
| Kitchen | Rangehood / extractor venting to outside | Recirculating rangehood fitted |
| Bathroom | Extractor fan ≥ 25 l/s to outside | Fan present but not venting to outside; fan below flow rate |
| Separate toilet | Extractor fan ≥ 25 l/s to outside | No fan installed |
| Habitable rooms | Openable area ≥ 5% of floor area | Rarely an issue in standard Auckland homes |
Healthy Homes compliance note: Extractor fans that vent into the ceiling space — rather than through the roof or an exterior wall — are non-compliant. This is a common installation shortcut in older Auckland properties. The fan must extract moisture and pollutants to outside the building envelope. See healthyhomes.govt.nz for the full ventilation standard.
Standard 4: Moisture Ingress and Drainage
What’s Required
The moisture ingress and drainage standard requires landlords to:
- Ensure the property has efficient drainage to remove surface water, stormwater, and groundwater — including gutters, downpipes, and stormwater drainage in good working order
- Install a ground moisture barrier under any suspended timber floor where the ground beneath the floor is exposed (i.e., not concrete) and where the crawl space is enclosed
- Ensure the property does not have any unreasonable moisture ingress — including fixing roof leaks, stopping rising damp, and addressing any plumbing leaks that contribute to moisture
Ground Moisture Barriers
The ground moisture barrier requirement catches out a significant number of Auckland landlords, particularly on older timber-framed homes. The barrier must cover at least 80% of the exposed ground beneath the floor, must overlap joins by at least 200mm, and must extend up the interior face of foundation walls or piles by at least 150mm. A basic 250 micron black polythene sheet correctly installed meets the requirement. Installing one in a typical Auckland home typically costs $600–$1,500 depending on access.
One of our property manager clients in Manukau recently flagged a rental where the ground moisture barrier under the house had never been installed — the floor was showing signs of moisture and the tenant was running heaters constantly. The barrier installation itself took half a day and cost under $900. The compliance risk and the ongoing moisture damage to the floor framing was worth considerably more than that to address.
💡 Property tip: If your Auckland rental has a suspended timber floor and you haven’t looked underneath it recently, get someone to inspect the crawl space. Missing or degraded ground moisture barriers, inadequate sub-floor ventilation, and early-stage joist deterioration are common and fixable — but only if they’re identified.
Standard 5: Draught Stopping
What’s Required
All unreasonable gaps and holes in walls, ceilings, floors, and around windows and doors that allow draughts must be stopped. Specifically:
- Unused fireplaces and chimneys must be blocked or fitted with a draught stopper
- Gaps around pipes, wiring, and ducting that pass through walls or floors must be sealed
- Windows and doors must close and latch properly
- Sub-floor vents must be present and in working order (not blocked — sub-floor ventilation is required; it’s draught entry into the living space that must be stopped)
What to Check
Draught stopping is typically the lowest-cost compliance item — most of the work involves sealing, caulking, and blocking gaps. The one item that surprises landlords is unused fireplaces: an unused fireplace chimney is one of the single largest sources of heat loss and draughts in a typical older Auckland home. Installing a removable chimney draught stopper or having the fireplace permanently sealed costs between $150 and $600 depending on the approach.
Healthy Homes compliance note: The draught stopping standard does not require sub-floor vents to be blocked — these are intentional ventilation openings. What must be stopped are unintentional gaps and holes between the exterior and the living space. Blocking sub-floor ventilation to satisfy draught stopping would itself create a compliance issue under the moisture ingress standard.
Full Checklist Summary
| Standard | Key Requirement | Typical Compliance Cost (if not met) |
|---|---|---|
| Heating | Fixed heater in main living room capable of heating to 18°C (calculated) | $1,800 – $3,500 (heat pump) |
| Insulation | Ceiling R2.9 (new) or R1.3 (existing acceptable); underfloor R1.3 | $800 – $3,500 (ceiling + underfloor) |
| Ventilation | Extractor fans venting to outside in kitchen and bathrooms; 5% openable windows | $300 – $1,500 (extractor fans) |
| Moisture ingress | No unreasonable moisture ingress; ground moisture barrier installed where required | $600 – $1,500 (moisture barrier) |
| Draught stopping | All unreasonable gaps sealed; unused fireplaces blocked | $200 – $800 |
If all five items require remedial work, a typical Auckland rental property can be brought to full Healthy Homes compliance for $4,000–$8,000. That compares very favourably to a single Tenancy Tribunal exemplary damages award of up to $7,200 per breach — which can be issued per standard, not just per complaint.
“The landlords who get into trouble with Healthy Homes are almost never the ones who tried and missed something. They’re the ones who assumed their property was compliant without actually checking against the specific thresholds. A proper assessment takes the guesswork out of it.”

What are the five Healthy Homes Standards in NZ?
The five Healthy Homes Standards are: (1) Heating — a fixed heater in the main living room capable of heating to 18°C; (2) Insulation — minimum R-values in ceiling and underfloor; (3) Ventilation — extractor fans in kitchens and bathrooms venting to outside; (4) Moisture ingress and drainage — including ground moisture barriers; and (5) Draught stopping — sealing unreasonable gaps including unused fireplaces.
What is the Healthy Homes compliance deadline for Auckland landlords?
For private landlords, all rental properties were required to comply with all five Healthy Homes Standards by 1 July 2025. Properties with new or renewed tenancy agreements from 1 December 2020 onwards were required to comply within 90 days of the tenancy start date. Check tenancy.govt.nz for the latest compliance deadline information.
What is the minimum heating requirement under Healthy Homes?
Rental properties must have a fixed heater in the main living room capable of heating that room to at least 18°C. The required heating capacity is calculated based on the room's floor area, ceiling height, number of exterior walls, windows, and Auckland's climate zone. Heat pumps are the most common compliant solution for Auckland landlords.
Does my rental property need a ground moisture barrier under Healthy Homes?
Yes, if the property has a suspended timber floor with exposed ground underneath and the sub-floor space is enclosed. The barrier must cover at least 80% of the exposed ground, with joins overlapping by at least 200mm and the barrier extending up foundation walls by at least 150mm. A standard 250 micron polythene sheet correctly installed meets the requirement.
What R-value insulation is required for Auckland rental properties?
For ceiling insulation installed after July 2016, the minimum R-value in Auckland (Climate Zone 1) is R2.9. Existing insulation installed before July 2016 is acceptable if it has an R-value of at least 1.3 and is in reasonable condition. Underfloor insulation must have a minimum R-value of 1.3 where installation is reasonably practicable.
Does my rental kitchen rangehood comply with Healthy Homes?
Only if it vents to the outside of the building. Recirculating rangehoods — which filter and return air to the kitchen — do not comply with the Healthy Homes ventilation standard. The rangehood or extractor fan must duct air to the exterior. This is one of the most commonly misunderstood requirements in Auckland rental properties.
What are the penalties for not complying with Healthy Homes Standards?
The Tenancy Tribunal can issue remediation orders requiring landlords to achieve compliance, and can award exemplary damages of up to $7,200 per breach. Breaches can be assessed per standard, meaning a landlord with multiple non-compliant areas faces multiple potential awards. Landlords must also include a signed Healthy Homes compliance statement in all tenancy agreements.
Can Superior Property Services help bring my Auckland rental up to Healthy Homes compliance?
Yes. We provide Healthy Homes compliance assessments and remediation across Auckland including heat pump installation, insulation upgrades, extractor fan installation, ground moisture barrier fitting, and draught stopping. One call covers all five standards. Contact us on 0800 199 888 or request a quote online — we respond within 1 working day.
Do I need a Healthy Homes assessment for every rental property I own?
Yes. Each rental property must individually comply with all five standards. A compliance assessment involves a physical inspection of each property against the specific thresholds — it cannot be assumed based on the general condition of the property or because similar properties in the area have been assessed.
