The healthy homes standards became law on 1 July this year. According to the Tenancy Services branch within the Ministry of Business, Innovation and Employment (MBIE), they introduce specific and minimum standards for heating, insulation, ventilation, moisture ingress and drainage, and draught stopping in rental properties.

The insulation standard, in particular, received a lot of attention as the 1 July deadline drew nearer. This is because it sets the guidelines for ceiling and underfloor insulation, which became compulsory for all rental homes where it was practicable to install.

Any insulation must comply with the regulations set out in New Zealand Standard NZS 4246:2016 Energy efficiency - Installing bulk thermal insulation in residential buildings and be safely installed. This standard explains the correct way to install insulation in an effective and safe way. It also includes guidance on what safety clearances are required from downlights, chimney flues, roofing and other objects.

To make it easier for landlords to comply with these insulation regulations, Tenancy Services have sponsored this standard for free download since 2016. This lets anybody view and print a single downloadable pdf at no charge, with printed copies available to order from Standards New Zealand.

The standard was previously located on the Tenancy Services website. However, the decision has been made to relocate it the Standards New Zealand website, where all other building and housing standards are situated. This includes the over 120 building standards sponsored for free download in early July 2019, together with all other building and housing standards.

You can find NZS 4246:2016 Energy efficiency - Installing bulk thermal insulation in residential buildings at this link.
