A major deadline is approaching for all New Zealand landlords: by 1 July 2025, every rental property must fully comply with the Healthy Homes Standards. These regulations are designed to ensure rental homes are warm, dry, and healthy by meeting minimum requirements in five key areas:

• Heating: A fixed heating source in the main living area

• Insulation: Adequate ceiling and underfloor insulation

• Ventilation: Openable windows and extractor fans in bathrooms and kitchens

• Moisture & Drainage: Efficient drainage and ground moisture barriers if needed

• Draught Stopping: Sealing gaps to prevent heat loss

Previously, compliance deadlines were staggered based on tenancy dates, provider and types, but from 1 July 2025, all rental properties must meet the standards, regardless of tenancy changes. Failure to do so can result in fines of up to $7,200 per breach under the Residential Tenancies Act.

While landlords are allowed to self-assess, the rules are complex. Many choose third-party professionals to ensure full compliance. Kōwhai Coast Property Management, for example, offers independent assessments as part of their onboarding process to help landlords start off on the right foot.

Key takeaways:

1. July 1, 2025 is the final deadline—no exceptions.

2. An assessment is the first step to confirm what’s needed.

3. Get professional help to avoid costly mistakes and protect tenant health.

For more help, landlords can consult Tenancy Services, Kōwhai Coast Property Management or a qualified compliance provider.
