New rules have come into force to make rental properties warmer and safer for tenants.   These rules took effect from 1 July 2016, and place some obligations on you as Landlord to get your rental property up to standard.

Some of the rules must be complied with straight away, while others leave you time to make the necessary changes.

Smoke alarms

All rental properties must have smoke alarms installed which meet the required standards. 


  • All new tenancy agreements must include a statement about the extent and safety of any insulation at the property.
  • Whenever you replace or install new insulation in your rental property, it must meet the required standards.  You can find out more about these standards through the Ministry of Business, Innovation and Employment. 
  • Insulation products which conduct electricity (such as reflective foil) are banned and must not be installed in rental properties.

By 1 July 2019 all rental properties must have underfloor and ceiling insulation which meets the required standard, wherever it can be practically installed.  This means that you must ensure your property has insulation in the ceiling and under the floors, unless it is impractical because of your rental property’s physical design.  

If you are a Landlord these changes are likely to affect you.  If you have any concerns about your obligations as a Landlord, contact your legal advisor for advice.
