Why has the Government introduced new requirements?
New Zealand government has introduced the Healthy Homes Standards to tackle health problems caused by underinsulated, old, damp and cold properties (of which NZ has many). The aim is to achieve warmer, drier homes by providing clear minimum standards for heating, insulation, ventilation, draught stopping, moisture ingress and drainage in rental properties.
When do I need to be compliant by?
- From 1 July 2019 - All landlords must state in new tenancy agreements that they will comply with new Healthy Homes regulations as required by the Residential Tenancies Act 1986.
This also applies to renewals and written variations to agreements.
Failure to include and sign this statement from 1 July may result in a financial penalty up to $500
- From 1 December 2020 - All new and renewed tenancy agreements will need to include the signed statement that landlord will comply with the new regulations AND outline specific information on how the landlord intends to comply (a template of compliance statement will become available at a later date)
Restrictions to property access during Covid-19 Alert Levels 3 and 4 limited landlords' ability to complete inspections to determine the level of compliance. The Government has extended the deadline for the compliance statement from 1st July 2020 to 1st December 2020.
- From 1 July 2021 - All landlords have to comply with Healthy Homes changes for new tenants. This also applies to renewed tenancies.
Following the feedback from the rental industry, the Government has announced changes to Heating, Ventilation and Moisture ingress and drainage standards. Learn more about this here New rules are expected to come into force in April 2022 and give landlords 90 days to comply. However, rentals that were not built to the 2008 code requirements or were not flats still had to comply with the current requirements.
- From 1 July 2024 - All rental homes must comply with the Healthy Homes Standards.
Remember that all five standards (heating, insulation, ventilation, draught stopping and moisture ingress and drainage) come into effect at the same time. Learn more
Healthy Homes Standards breakdown
More detailed regulations are coming but here's what the standards currently specify:
Heating
A fixed heating device capable of warming the room to at least 18°C needs to be installed in the main living room only.
- By 'living room' the standard also covers a lounge, dining room, sitting room or an open plan living area.
- The 'main living room' is the largest living room.
- Only the main living room requires heating.
- A landlord will not be required to provide a heater for tenants' bedrooms.
- Some heaters are considered inefficient, unaffordable to operate or unhealthy to meet the standard and so won't meet the requirements (e.g. LPG bottle heaters, open fires and electric heaters (not heat pumps) with heating capacity more than 2.4 kilowatts)
- The online heating tool was developed by Tenancy Services to help landlords identify what capacity heater is required for their rental property.
If a landlord installed a heater before 1 July 2019 as long as the heating capacity is within 10% of the kilowatts required, the device will meet the standard.

Following the feedback from the rental industry, the Government has announced changes to the Heating standard. Learn more about this here. The heating formula will be amended to allow smaller heating devices to be installed in new homes. (New rules are expected to come into force in April 2022)
Insulation
Both ceiling and underfloor insulation should meet the minimum of the 2008 Building Code or (for existing ceiling insulation) to be at least 120mm thick
- Existing 2016 RTA regulation requires all rental properties (with accessible ceilings and underfloors) to be insulated by 30 June 2019.
- After 1 July 2021 the Healthy Homes Standards increase the minimum insulation requirement from 70mm to 120mm thick.
Existing insulation may meet the standard — or not
- If your property was not insulated and you had to put fresh insulation in to meet the 2016 standards, you're likely to comply with new standards (Safe to check it still)
- If your property was already insulated and you didn't need to do anything to meet the 2016 standards, you need to check the insulation to make sure it's at least 120mm thick. If not, the property requires a "top up".
- If your insulation meets new standards, it still needs to be in reasonable condition (check for damage, dampness, rips, gaps in the coverage, contamination etc)
- If the property has an inaccessible roof or a concrete pad, an insulation exemption will continue to apply.
You absolutely can install insulation yourself although Tenancy Services recommends using qualified installers to ensure compliance.

Ventilation
All rental properties should have opening doors and windows in dining rooms, living rooms, bedrooms, kitchen and other living spaces.
A right size extractor fans should be installed in all kitchens and bathrooms.
- If there are multiple bathrooms and kitchens, an appropriate size extractor fans are needed to be installed in all rooms.
- An extractor fan needs to ventilate externally
- If there is a shower dome in the bathroom, an extractor fan is still needed to be installed.
- A range hood in the kitchen can be suitable if it ventilates to the outside.
- The openable windows and doors in a room must have a total area of 5% of the floor area in their respective rooms.
There is an exemption to this rule for bathrooms and kitchens where it's not reasonably practicable to install an extractor fan. There is another exemption to properties that were lawfully built but don't have an openable window or door in one of the rooms.
Learn more about the Ventilation Standard requirements
Following the feedback from the rental industry, the Government has announced changes to the Ventilation standard. Learn more about this here. Continuous mechanical ventilation systems used in properties built to comply with the current building code will now also satisfy the standard. This applies to systems that received building consent on or after 1 November 2019. (New rules are expected to come into force in April 2022)
Moisture and drainage
There needs to be efficient drainage and guttering, downpipes and drains. If a rental home has an enclosed subfloor, it must have a ground moisture barrier if it's reasonably practicable to install one.

Following the feedback from the rental industry, the Government has announced changes to the Moisture and drainage standard. Learn more about this here. Landlords will be given an exemption to remove the need to install alternative moisture barriers where the installation of a polythene barrier isn’t reasonably practical. (New rules are expected to come into force in April 2022)
Draught-stopping
Rental properties must have no unnecessary gaps or holes in walls, ceilings, windows, floors, and doors that cause noticeable draughts.
All unused chimneys and fireplaces must be blocked.
- All the open fireplaces and chimneys must be blocked unless a landlord and tenant agree otherwise.

Keeping records
A landlord needs to ensure their rental properties meet the standards by the deadline. However, regardless of any work required, a landlord also needs to keep records of how they're complying with the Healthy Homes Standards. These records may include:
- compliance certificates
- records of calculations
- invoices from builders
- receipts for materials purchased
- product manuals etc
These records can be presented to the Tenancy Tribunal or the Tenancy Compliance and Investigation Team when resolving potential disputes.
