Good quality insulation is the single most effective measure for helping to keep the heat in during winter and out during summer.

Insulation statements required in tenancy agreements

From July 2016, new tenancy agreements must contain a signed Insulation Statement from the landlord. This must disclose whether insulation is fitted in the rental premises, the type, its location and condition. This is so tenants know what conditions to expect over winter and can make an informed decision.

A landlord who does not make a complete Insulation Statement or includes anything they know to be false or misleading, is committing an unlawful act and may be liable to pay a penalty of up to $500.

Insulation complusory in all rental home form 1 July 2019

Any new, replacement or top-up insulation installed in a rental home after 1 July 2016 must meet mandatory requirements that will apply from 1 July 2019. Ceiling and underfloor insulation must be installed, where it is reasonably practicable to do so. Wall insulation is not compulsory.

Some landlords may be eligible for subsidised insulation installed through the Warm Up New Zealand: Healthy Homes programme. Go to for more information. A number of councils around New Zealand also allow homeowners to add the cost of insulation to their rates and pay it back over approximately nine years.

A landlord who fails to comply with the insulation regulations is committing an unlawful act and may be liable for a penalty of up to $4,000.
