Your rental property must pass all five Healthy Homes Standards by law. Non-compliance carries fines up to $7,200 per breach for small landlords (1–5 properties) and up to $50,000 for larger landlords with 6+ properties. If you’re self-managing, there’s no wiggle room — tenants can claim exemplary damages up to $6,500, and Tenancy Services inspectors have the right to check your property at any time. Here’s the complete checklist so you know exactly what’s required, what it costs, and what happens if you fail.
1. HEATING — Keep It Above 18°C
Tenancy Services heating standard requires your main living room to reach and maintain at least 18°C during winter.
- Your main living room must have one or more fixed qualifying heaters (not portable heaters or ceiling fans)
- The heater must have enough power to warm the room to 18°C on the coldest winter day
- You must calculate heating capacity using a specific formula based on room dimensions and insulation level
- Common qualifying heaters: heat pumps, fixed electric heaters, wood burners, gas fires with ducting
- Portable heaters, bar radiators, and plug-in electric heaters do NOT count
What this means for landlords: Most Auckland properties need a heat pump installation ($2,500–$5,000) or a fixed electric heater. If your property has an older wood burner or gas fire, you need to check the heat output spec. A common mistake is installing the wrong wattage heater or forgetting to calculate room dimensions properly. If you’re unsure, have a heating engineer do a free assessment.
2. INSULATION — Ceiling and Underfloor Required
Insulation standards are mandatory in all NZ rental homes since 1 July 2019. Your property must meet 2008 Building Code minimum or better.
- Ceiling insulation: minimum R-value 1.5 (typically 100mm batts or blown fibre)
- Underfloor insulation: minimum R-value 1.3 (requires access to subfloor space)
- Properties built after 2008 may already be compliant; properties before 2000 almost certainly aren’t
- Bulk insulation (fiberglass, polyester, wool) is standard; reflective foil alone does not meet the standard
- Cost: typically $2,000–$5,000 depending on home size and access difficulty
What this means for landlords: If your rental is pre-2000, budget for insulation work. This is the fastest way to lose compliance credibility with Tenancy Services. Do not skip it. Get a certified installer — dodgy DIY insulation will fail an inspection.
3. VENTILATION — Extract Fans and Openable Windows
Ventilation standards prevent moisture buildup and mold — a major compliance failure point.
- Every habitable room must have openable windows or doors (at least 5% of floor area)
- Kitchens with a cooktop must have a ducted rangehood (ducted to outside, not recirculating)
- Every bathroom and shower room must have either an extraction fan or operable window
- Extraction fans must duct to the outside — not into the roof or attic space
- Fan sizing matters: too small and it’s ineffective; too large and tenants won’t use it
What this means for landlords: This is where many landlords fail. A recirculating rangehood or bathroom fan vented into the roof is not compliant. Tenants see condensation, mold appears, you get cited. Budget $500–$1,500 for proper fan installation with exterior ducting. Make sure your installer understands the standard — some tradespeople still install non-compliant fans.
4. MOISTURE & DRAINAGE — Stop Water Ingress and Damp Subfloors
Moisture and drainage standards are critical in Auckland’s wet climate.
- All properties must have effective drainage for storm water, surface water, and groundwater
- Properties with an enclosed subfloor space must have a ground moisture barrier (polythene sheet minimum 0.2mm thick)
- No signs of water ingress: no damp patches, mold, rot, or water stains on walls or ceilings
- Gutters and downpipes must be clear and draining properly
- Ground around the property should slope away from the foundation
What this means for landlords: Check your subfloor. If it’s damp or soggy, install a moisture barrier (usually $1,000–$3,000). Inspect gutters and downpipes regularly — Auckland rain is heavy. Look for water stains on ceilings and walls; if you find them, fix the leak before compliance is assessed. Damp is one of the easiest things for tenants to spot and report.
5. DRAUGHT STOPPING — Seal Gaps, Cracks, and Holes
Draught stopping standards are about blocking heat loss through gaps and cracks.
- No unreasonable gaps or holes in walls, ceilings, floors, or around windows and doors
- Gaps around pipes, chimneys, vents, and electrical penetrations must be sealed
- Weatherstripping on external doors and windows is essential
- Larger holes (ceiling access points, missing plasterboard, gaps in framing) are obvious failures
- Draught tape, spray foam, and caulk are your friends here — cost is usually under $500
What this means for landlords: Walk through your property with fresh eyes. Look up. Look at door frames and window seals. Spray foam any obvious gaps. This is the cheapest standard to fix, so do not fail on this one. It signals to inspectors that you don’t care about compliance.
Fines and Enforcement — What Happens If You Fail
Tenancy Services and the Tenancy Tribunal have real enforcement teeth.
- Small landlords (1–5 properties): up to $7,200 per breach per property
- Larger landlords (6+ properties): up to $50,000 per breach
- Tenants can claim exemplary damages up to $6,500 on top of any fine
- Tenancy Services can inspect any property at any time if a tenant complains
- You cannot increase rent or issue a termination notice without providing a written Healthy Homes compliance statement in the tenancy agreement
- Non-compliant statements can trigger a Tenancy Tribunal application
Recent enforcement: In the first half of 2025, Tenancy Services completed over 900 proactive assessments and found breaches in nearly 270 cases — roughly 30%. The trend is tightening, not loosening.
Common Mistakes Auckland Landlords Make
- Wrong heating capacity calculation. You can’t just guess — use the Tenancy Services heating calculator or hire a heating engineer. A heater that’s too small fails the standard even if it’s a quality unit.
- Recirculating rangehoods. Many landlords install a “ductless” rangehood that just filters and recirculates air. This does not meet the standard. It must duct to outside.
- Bathroom fans vented into the roof. Same problem. Fans must duct outside, not into the ceiling cavity or attic space.
- No subfloor moisture barrier. If your subfloor is enclosed, there must be a polythene ground moisture barrier. Skipping this is a guaranteed failure.
- Forgetting to update the compliance statement. Every time you have a new tenancy, you must provide a written statement confirming all five standards are met. Failing to include this statement is a breach in itself — even if your property actually complies.
- Paying a handyman instead of a licensed tradesperson. Faulty work fails inspection. Hire licensed installers for heating, ventilation, and insulation.
What This Means If You Self-Manage
If you self-manage your rental, you are personally responsible for compliance. You must understand all five standards, manage contractor bookings and payments, keep records of all work completed, and ensure your compliance statement is correct on every tenancy agreement. One missed standard costs you up to $7,200. One missing or incorrect statement costs you another breach. Tenants will report you if something’s wrong — mold, condensation, drafts, cold rooms — and Tenancy Services will inspect within days. The paperwork alone takes hours each year. The risk is real. And if you’re unsure whether your property actually meets the standard, Tenancy Services will find out.
And if you’d rather not manage it yourself, that’s exactly what Keyvi is here for.
