If you're a tenant, there are things you can do to improve the health and comfort of the property you are renting.


The Residential Tenancies Act (RTA) aims to make homes warmer, drier and safer for the million New Zealanders who live in rented accommodation. Landlords are required to provide a statement on new tenancy agreements about the location, type and condition of insulation in the home.

In addition, all rental homes will be required to have ceiling and underfloor insulation by 1 July 2019 (where it is practical to retrofit). Rental homes that already have insulation must be upgraded if the ceiling and underfloor insulation is no longer in reasonable condition. If the home you rent does not have insulation in the ceiling or floor yet, talk to your landlord about when they are intending to get it retrofitted.

For more information about the requirements, visit the Tenancy Services website.

Some councils will let your landlord add the cost of insulation to the rates, and there are also insulation companies that offer special discounts.

Ventilating a home is essential for removing excess moisture from your home - damp homes can be mouldy and bad for your health. The simplest and cheapest way to ventilate is opening doors and windows a few times every day. If your home has externally vented extractor fans in the kitchen and bathrooms, make sure you use them to get rid of moisture.

?Ventilation checklist


Heating your home is important for your health and comfort. Aim for a minimum of 18?C. Inadequate heating can lead to mould growth and dampness.

If the home you are renting comes with a heater, learn how to use it wisely.

?Using heat pumps wisely

?Using wood burners wisely

?Using pellet burners wisely

?Using electric heaters wisely

Avoid using:

  • Unflued gas heaters - whether portable or fixed - which release toxic fumes and make your house damp. Cheap portable electric heaters are safer and cost less to run. Some fixed gas heaters only have one pipe or hose for the gas supply, but do not have a flue going out through an external wall or through the roof – using these should also be avoided.
  • Open fire places - they are inefficient and draughty. Most of the heat is lost up the chimney.
