Every rental property in New Zealand must comply with the Healthy Homes standards. No exceptions. No grace period. If your Kerikeri rental doesn’t meet all five standards right now, you’re exposed to fines, Tribunal orders, and tenant disputes — whether you know about the issues or not.

The standards have been fully enforceable since July 2021, yet a significant number of rental properties nationwide still fall short. In the Far North, where older housing stock is common and humidity is a year-round challenge, the gaps tend to be bigger than landlords expect.

This guide breaks down exactly what each standard requires, what it means for properties in Kerikeri specifically, and what to do if you’re not sure where you stand.

What are the Healthy Homes standards?

The Healthy Homes standards are five minimum requirements for all residential rental properties in New Zealand. They were introduced under the Residential Tenancies (Healthy Homes Standards) Regulations 2019 and became enforceable for all tenancies from 1 July 2021.

The five standards cover heating, insulation, ventilation, moisture and drainage, and draught stopping.

Who do these apply to? Every private landlord, property manager, boarding house operator, and social housing provider with a current or new tenancy agreement. If someone is paying rent to live in your property, the Healthy Homes standards apply.

The five standards explained

1. Heating

The main living area must have a fixed heating device that can heat the room to at least 18°C. Portable heaters don’t count. The heater must be appropriately sized for the room — MBIE provides a heating assessment tool to calculate the required capacity in kilowatts.

What this looks like in Kerikeri: Heat pumps are the go-to solution for most Bay of Islands properties. Kerikeri’s winters are mild compared to the South Island, but the persistent humidity means you need a heating source that also dries the air. A quality heat pump sized at 4–6kW handles most Kerikeri living rooms comfortably and doubles as cooling in summer. Budget roughly $2,500–$4,000 installed depending on the unit and property access.

2. Insulation

Ceiling and underfloor insulation must meet minimum R-values set by the standard:

Ceiling insulation: R 2.9 for most of the North Island (Zone 1), or existing insulation if installed after 1 July 2016
Underfloor insulation: R 1.3, or existing insulation if installed after 1 July 2008

Insulation must be in reasonable condition — compressed, water-damaged, or missing batts don’t count.

Common Kerikeri pitfall: Many homes built in the 1970s–1990s in the Kerikeri area have some ceiling insulation, but it’s often degraded, compressed by storage, or has gaps around downlights and access hatches. “It was insulated when we bought it” doesn’t mean it still meets the standard. Get it inspected.

3. Ventilation

All habitable rooms must have openable windows
Kitchens must have a rangehood or extractor fan ducted to the outside
Bathrooms must have an extractor fan or an openable window (an extractor fan is strongly recommended)

What this looks like in Kerikeri: Natural ventilation is rarely the problem here — most Kerikeri homes have plenty of windows. The issue is usually the kitchen. Many older homes have recirculating rangehoods that filter air and push it back into the room rather than ducting it outside. That doesn’t meet the standard. Retrofitting external ducting for a kitchen rangehood typically costs $300–$800.

4. Moisture ingress and drainage

This standard requires:

Efficient drainage for the removal of surface water, including gutters and downpipes
A moisture barrier (ground vapour barrier) over any enclosed subfloor space
No fixed water leaks
No signs of sustained, visible dampness or mould

Kerikeri’s climate makes this critical. The Bay of Islands receives over 1,600mm of rainfall annually. Subfloor moisture barriers are often missing in older homes, and blocked gutters or disconnected downpipes can push water straight under the house. This standard catches a lot of Kerikeri landlords off guard — it’s not just about fixing leaks, it’s about managing the water the climate delivers daily.

5. Draught stopping

All unused open fireplaces must be blocked or sealed
Gaps and holes in walls, ceilings, windows, floors, and doors that cause noticeable draughts must be fixed

This is usually the least expensive standard to address, but it’s the one most often overlooked. Common culprits include unsealed gaps around pipe penetrations, missing door seals, and single-glazed windows with degraded putty.

What happens if your property isn’t compliant?

Non-compliance isn’t just a technical issue — it has real financial and legal consequences.

$7,200

Maximum fine per breach at the Tenancy Tribunal, with exemplary damages of up to $50,000 in serious cases

Here’s what you’re risking:

Tenancy Tribunal work orders — a tenant can apply to the Tribunal at any time, and the Tribunal can order you to remedy the breach and pay compensation
Infringement notices — MBIE can issue $4,000 infringement notices without going to the Tribunal
Insurance complications — some insurers are starting to ask about Healthy Homes compliance; non-compliance could affect claims
Difficulty attracting quality tenants — informed renters (and their advocacy groups) increasingly check compliance before signing a lease

The bottom line

Compliance isn’t optional, and the cost of bringing most Kerikeri properties up to standard is far less than the cost of a single Tribunal order. For a typical three-bedroom home, full compliance work ranges from $3,000 to $8,000 — and most of that is the heat pump.

How to check if your property is compliant

You have three options:

Self-assess using the Tenancy Services Healthy Homes checklist. This is free but requires you to understand the technical requirements and measure things like room volume for heating calculations.
Hire a Healthy Homes assessor. Independent assessors will inspect your property and provide a compliance report. Expect to pay $250–$450 for a full assessment in the Kerikeri area.
Use a property manager who includes it. At Latitude 35, Healthy Homes assessment is part of our standard onboarding — we assess every property against all five standards, provide a clear report on what’s compliant and what’s not, and coordinate any remediation through our network of local tradespeople.

A compliance checklist for Kerikeri landlords

Use this as a quick self-check before your next tenancy renewal:

Heat pump or fixed heater in the main living room, sized to the room
Ceiling insulation at R 2.9 or above, in good condition
Underfloor insulation at R 1.3 or above (if applicable)
Kitchen extractor fan ducted to outside (not recirculating)
Bathroom extractor fan or openable window
All habitable rooms have openable windows
Gutters and downpipes clear and connected
Ground vapour barrier in enclosed subfloor areas
No fixed leaks or signs of sustained dampness
Unused fireplaces blocked or sealed
No noticeable draughts from gaps in walls, floors, windows, or doors
