In New Zealand, the five healthy home standards, which were introduced as regulations aimed at improving the quality of rental housing, include:
- Heating: A fixed heating device must be provided in the main living area that can heat the room to at least 18°C during the winter months.
- Insulation: Ceiling and underfloor insulation must meet the required standards to retain heat and improve energy efficiency.
- Ventilation: Adequate ventilation must be provided, including windows that open and extractors in rooms with a bath or shower, to reduce moisture and maintain indoor air quality.
- Moisture and Drainage: Homes must have efficient drainage systems to remove stormwater, and any ground moisture issues must be mitigated to prevent dampness and mould.
- Draught Stopping: All unnecessary gaps or holes in walls, ceilings, windows, floors, and doors must be blocked to prevent draughts and maintain warmth.
