Insulation and Heating Requirements for Rentals

In the pursuit of healthier, warmer homes for all Kiwis, the New Zealand government developed The Healthy Homes Standards.

These standards aim to ensure that rental properties meet specific criteria for heating, insulation, ventilation, moisture, drainage, and draughts. 

All rental properties must adhere to these standards by 1st July 2025 - so both landlords and tenants must understand the requirements:

  1. Heating Requirements:
  • Landlords must provide one or more fixed heaters that can directly heat the main living room with a minimum temperature of 18˚C.
  • Accepted forms of heating include heat pumps, wood burners, or electric heaters.
  1. Insulation Requirements:
  • Ceilings and underfloor spaces must be adequately insulated to prescribed R-values.
  • The minimum insulation requirements vary depending on the region and climate zone of the property.
  1. Ventilation Requirements:
  • Rental homes must have openable windows in the living room, dining room, kitchen and bedrooms. 
  • Kitchens and bathrooms must have extractor fans or an acceptable continuous mechanical ventilation system.
  1. Moisture and Drainage:
  • Rental properties must have efficient drainage for the removal of stormwater, surface water and groundwater. 
  • Rental properties with an enclosed sub-floor space must have a ground moisture barrier.
  1. Draught Stopping:
  • Landlords must make sure the property doesn't have unreasonable gaps or holes in walls, ceilings, windows, skylights, floors and doors which cause noticeable draughts. 
  • All unused open fireplaces must be closed off, or their chimneys must be blocked to prevent draughts.

Landlords are encouraged to take proactive steps towards meeting these standards to avoid penalties and ensure the comfort of their tenants. Additionally, tenants should understand their rights regarding healthy homes and communicate any concerns to their landlords promptly.

Over 600,000 New Zealand households rent, and research shows that rental properties often have a lower quality of living when compared with owner-occupied homes. Cold, damp, and mouldy living conditions are associated with health issues like asthma and cardiovascular conditions.

Enhancing rental home quality not only promotes better health for tenants but also safeguards landlords' investments.
