90 Day Notice NZ Landlord: How to End a Periodic Tenancy Without Giving a Reason

Since 30 January 2025, New Zealand landlords can again end a periodic tenancy by serving 90 days' written notice without stating a reason. The Residential Tenancies Amendment Act 2024 restored this right after it was removed in February 2021. A notice that's short by even one day can be invalid, though Section 51(7) lets the Tribunal vary certain inadvertent defects if they are corrected promptly and without unfairness to the tenant.

What the 90-Day No-Cause Notice Actually Does

Section 51(1) of the Residential Tenancies Act 1986 lets a landlord terminate a periodic tenancy by giving the tenant 90 calendar days' written notice. You don't need to explain why. The notice ends the legal tenancy on the specified date — it doesn't physically remove anyone. If the tenant stays past that date, you need a Possession Order from the Tenancy Tribunal (more on that below).

The notice must include:

• The full address of the rental property
• The exact calendar date the tenancy will end
• Your signature (or your agent's) and the date you signed it

Tenancy Services provides a free template (the "Notice to end a periodic tenancy — 90 days' notice" PDF), but the template doesn't calculate your dates for you. That's where most landlords go wrong.

How to Calculate the Correct End Date

The 90-day count doesn't start when you write the notice or when you drop it in the letterbox. It starts the day after the tenant is deemed to have received it, and the deemed receipt date depends on your delivery method:

Hand delivery — deemed received the same day.

Letterbox or attached to the door — deemed received 2 working days later.

Post (to the address for service or PO Box) — deemed received 4 working days later.

Email (to an address for service in the tenancy agreement) — deemed received the same day if sent before 5:00 PM, or the next working day if sent after 5:00 PM.

Working days are Monday to Friday, excluding public holidays and your regional anniversary day. Once you have the deemed receipt date, day one of the 90 calendar days is the following calendar day.

Example: You post a notice on Friday 1 May 2026. Skip the weekend (not working days), then count four working days: Monday 4 May, Tuesday 5 May, Wednesday 6 May, Thursday 7 May. Deemed receipt is 7 May. Day one is Friday 8 May. The earliest lawful end date is Thursday 6 August 2026 — exactly 90 calendar days later.

If you put 5 August on the notice instead, it's invalid.

The Retaliatory Notice Trap

You don't need a statutory reason for a 90-day notice, but it must meet the Act's requirements and cannot be retaliatory under Section 54. A tenant may apply to the Tribunal for a retaliatory finding within 12 months after the notice is issued. If they apply within 28 working days after receiving it, they can also ask for the notice to be declared of no effect.

If the Tribunal finds the notice was motivated wholly or partly by retaliation, it must declare the notice retaliatory. If the tenant also applied within 28 working days after receiving it for an order that the notice be of no effect, the Tribunal can set it aside; the landlord may also face exemplary damages. This doesn't mean you can never issue a 90-day notice after a repair request. It means you need a genuine, independent reason and ideally a documented timeline showing the decision predates the tenant's complaint.

Keep a brief communication log noting when you first considered ending the tenancy and why. If it ever reaches the Tribunal, contemporaneous notes carry far more weight than an after-the-fact explanation.

Can You Email the Notice?

Yes, but only if the tenancy agreement specifies an email address as an "address for service." A personal email you've been casually using for maintenance messages doesn't automatically count. Check your tenancy agreement.

If email is a valid address for service and you send the notice at 4:45 PM on a Wednesday, deemed receipt is that same day. Send it at 5:15 PM and it rolls to Thursday. Send it at 5:15 PM on a Friday and it rolls to Monday (the next working day). These differences can push your end date out by days.

Standard text messages and messaging apps (WhatsApp, Facebook Messenger) are not valid service methods unless explicitly designated as an address for service in the agreement.

What Happens If the Tenant Doesn't Leave

When the notice period expires and the tenant remains, the tenancy has legally ended but you cannot change the locks, cut off utilities, or remove their belongings. That's a self-help eviction and it's unlawful under Section 63 of the RTA — you'll face exemplary damages of up to $6,000.

Instead, apply to the Tenancy Tribunal for a Possession Order under Section 64. The filing fee is $29 (from 1 July 2026). If the tenant still refuses to leave after the Possession Order, file it with the District Court for a Warrant to Enforce Possession. Only court bailiffs have the legal authority to physically enforce possession.

Common Mistakes That Invalidate a 90-Day Notice

• Wrong date math: Forgetting to add the service delivery allowance before starting the 90-day count
• No signature: The notice must be signed and dated
• Wrong tenancy type: This notice is for periodic tenancies only — if you have a fixed-term, you need the 90-to-21-day non-continuation notice instead
• Missing address: The full property address must appear on the notice
• Casual delivery: Handing it to a flatmate, sliding it under the door, or texting it aren't valid service methods

If your notice is defective, the Tribunal may declare it invalid and you may need to serve a fresh notice. Section 51(7) allows the Tribunal to vary certain inadvertent defects if they are corrected promptly and without unfairness to the tenant.
