Residential Tenancy Laws in NZ 2025: What Changed?

If you're renting in New Zealand, 2025 brought some significant changes to the Residential Tenancies Act that affect both landlords and tenants. Whether you're in a periodic or fixed-term tenancy, understanding these updates is crucial for protecting your rights and staying compliant. Let's walk through what changed and how it impacts you.

The Major Changes to Tenancy Terminations

The biggest shake-up in 2025 came on 30 January, when new rules around how tenancies can be ended came into force^[1]. These changes rolled back some protections introduced in 2020 and introduced new flexibility for both landlords and tenants.

Notice Periods: What's Different Now?

If you're a tenant wanting to leave a periodic tenancy, you'll now only need to give 21 days' notice, down from the previous 28 days^[1]. This gives you more flexibility to move on when your circumstances change.

For landlords, the changes are more substantial. They can now end a periodic tenancy with 90 days' notice without needing to provide a specific reason^[1]. This is the controversial 'no cause' termination that's been widely discussed in rental communities.

However, if a landlord needs the property for specific purposes, they can give shorter notice:

• 42 days' notice if the landlord or a family member needs to live in the property as their main residence for at least 90 days^[1]
• 42 days' notice if the property has been sold and vacant possession is required^[1]
• 42 days' notice if the property is needed for the landlord's employee or contractor^[1]

It's important to note that these new notice periods only apply to termination notices issued from 30 January 2025 onwards. If notice was already given before this date, the old rules still apply^[1].

Fixed-Term Tenancies: Automatic Conversion to Periodic

From 30 January 2025, fixed-term tenancies will automatically convert to periodic tenancies when they expire, unless either party gives notice of termination between 90 and 21 days before the end of the fixed term^[1]. Alternatively, both parties can agree to renew the fixed term or end the tenancy.

There's a 90-day transition period for existing fixed-term tenancies, so these automatic conversion rules only apply to fixed-term tenancies expiring on or after 1 May 2025^[1].

Enhanced Protections Against Retaliatory Termination

One of the strongest protections for tenants in the 2025 reforms is expanded safeguards against retaliatory termination. If your landlord tries to end your tenancy because you've exercised your legal rights—such as reporting a maintenance issue or requesting repairs—you can now challenge this at the Tenancy Tribunal^[1].

The timeframe to challenge a retaliatory termination notice has been extended to 12 months, giving you much stronger grounds to fight an unfair eviction^[1]. This is a significant win for tenant protection.

Modernising Communication: Electronic Notices Now Allowed

From 20 March 2025, the way landlords and tenants communicate changed significantly^[1]. Tenancy-related documents and notices can now be exchanged electronically if both parties agree, including via email, fax, mobile telephone, or instant messaging^[1].

However, a physical address for service still needs to be provided in your tenancy agreement as a backup^[1]. This modernisation should speed up communication and reduce delays in resolving issues.

New Rules Around Smoking and Pet Bonds

Indoor Smoking Bans

From 20 March 2025, landlords can now explicitly ban indoor smoking in tenancy agreements, and this clause is fully enforceable^[1]. Landlords can also restrict smoking in outbuildings, provided any additional outdoor restrictions align with tenants' right to quiet enjoyment of the property^[1].

Pet Bonds and Consent

New provisions dealing with pet-related rights and responsibilities are coming, but the exact date hasn't been set yet. These rules will allow tenants to request consent to keep pets and will enable landlords to require a 'pet bond' from tenants^[1]. We'll update you once the specific implementation date is announced.

Changes to the Tenancy Tribunal

The Tenancy Tribunal is being modernised to operate more efficiently. From 20 March 2025, the Tribunal can make decisions based on submitted documents alone, without holding a hearing, as long as the case doesn't involve termination or landlord access^[1].

Additionally, the jurisdictional limit for consolidated applications involving multiple properties owned by one landlord has changed to $100,000 per tenancy, instead of $100,000 for the entire application^[1].

Online Bond Lodgement

Bond lodgement provisions requiring online lodgement came into effect on 17 December 2024^[1]. This means landlords must now lodge bonds electronically rather than through traditional methods, streamlining the process and providing better protection for tenants' money.

What These Changes Mean for You

For Tenants

The 2025 changes are mixed for tenants. On the positive side, you've got more flexibility to leave a tenancy (21 days' notice instead of 28), stronger protection against retaliatory evictions, and faster communication through electronic notices. However, the reintroduction of 'no cause' terminations with 90 days' notice does reduce your security in a periodic tenancy.

The key is understanding your rights. If your landlord tries to evict you for reporting maintenance issues or exercising your legal rights, you now have a 12-month window to challenge this at the Tenancy Tribunal.

For Landlords

Landlords have gained more flexibility with 'no cause' terminations and shorter notice periods for specific circumstances. However, you'll need to be careful not to terminate tenancies in a way that could be seen as retaliatory, as tenants have stronger grounds to challenge these actions.

Practical Tips for Staying Compliant

• Review your tenancy agreements to ensure they include electronic contact details if you want to serve notices electronically
• Document everything if you're considering ending a tenancy, to avoid any appearance of retaliation
• Use the new 21-day notice period if you're a tenant wanting to move—it gives you more flexibility than before
• Check your bond was lodged online by your landlord after 17 December 2024
• Clarify smoking policies in your tenancy agreement if you have specific rules about this
• Stay informed about pet bond rules, which are coming later in 2025

What You Should Do Now

If you're renting in New Zealand, take time to review your tenancy agreement and make sure it reflects these new rules. If you're a tenant, ensure your landlord has your current electronic contact details if you want to receive notices by email. If you're a landlord, update your tenancy agreements to include electronic contact information and clarify any smoking policies.

The 2025 tenancy law changes represent a significant shift in how rentals work in Aotearoa. While there are changes to benefit both landlords and tenants, the key is understanding your rights and responsibilities under the new rules.
