Fixed Term Tenancy Ending NZ: The 90-to-21-Day Window and Automatic Rollover

A fixed-term tenancy in New Zealand doesn't automatically end on its expiry date. Under Section 60A of the Residential Tenancies Act 1986, it converts into a periodic tenancy the day after expiry unless the landlord gives non-continuation notice within the statutory window, the tenant gives at least 21 days' written notice, or the parties agree otherwise. Miss the deadline and you're locked into an ongoing tenancy that requires a separate notice process to terminate.

The 90-to-21-Day Notice Window

To prevent a fixed-term tenancy from rolling over into a periodic agreement, you need to serve written notice of non-continuation. The timing rules are strict:

• Earliest you can serve notice: 90 days before the expiry date
• Latest you can serve notice: 21 days before the expiry date

Serve the notice one day too early (91 days before) and it's invalid. Serve it one day too late (20 days before) and the window has closed.

Since the Residential Tenancies Amendment Act 2024 took effect on 30 January 2025, landlords no longer need to specify a reason for non-continuation. You simply notify the tenant that you don't wish the tenancy to continue beyond the fixed term.

The tenant has the same option: they can give at least 21 days' written notice before expiry to end the tenancy at term.

What "Automatic Rollover" Means

If nobody serves notice within the window, the fixed term expires but the tenancy doesn't end. Instead, on the day after the expiry date, it becomes a periodic tenancy on the same terms. Same rent, same conditions — just no fixed end date.

Once it's periodic, ending it requires a separate process: either a 90-day no-cause notice, a 42-day notice (if you meet one of the three statutory grounds), or a breach-based route. You can't retroactively end the tenancy because you meant to serve a non-continuation notice but forgot.

This is a common trap for landlords managing multiple properties. If you have a fixed-term tenant you don't want to keep, put the 90-day and 21-day deadline dates in your calendar the day the tenancy agreement is signed.

Calculating Your Dates

The notice must be served within the window — which means adding the delivery deeming allowance before checking whether you're inside the 90-to-21-day range.

Example: Fixed term expires 1 March 2027. You want to post the notice.

90 days before 1 March = 1 December 2026 (earliest lawful service — but deemed receipt would be 4 working days after posting, so you need to post earlier to land inside the window)

Actually, the window refers to when the tenant is deemed to receive the notice, not when you post it. Post on 25 November, deemed receipt 4 working days later = 1 December (if no holidays intervene) — that's 90 days before expiry, right on the boundary.

21 days before 1 March = 8 February 2027. If you post on 2 February, deemed receipt is 8 February — 21 days before expiry, within the window. But if you post on 4 February, deemed receipt could be 10 February — only 19 days before expiry, outside the window, and the notice is invalid.

The margins are thin. Hand delivery gives you the most control because deemed receipt is immediate.

Can You End a Fixed Term Early?

Standard termination notices (90-day, 42-day) don't apply to unexpired fixed terms. You can't issue a 90-day no-cause notice to end a tenancy that still has six months left to run. Early termination of a fixed term requires one of these:

Mutual agreement — both parties agree in writing to end early on negotiated terms.

Tribunal order for severe hardship (s 66) — if unforeseen circumstances cause hardship to one party that outweighs the hardship to the other, the Tribunal can order early termination. This is discretionary and not guaranteed.

Unlawful premises (s 56A) — if the dwelling doesn't have the required building consents or fails council sanitary standards, the tenancy can be terminated immediately.

Physical assault (s 55AA) — the landlord can issue 14 days' notice if the tenant has physically assaulted the landlord, their family, or their agent, and the police have filed charges.

Family violence exit (s 56B) — this is a tenant-initiated route, not available to landlords. A tenant experiencing family violence can withdraw from any tenancy (periodic or fixed-term) with 2 days' notice.

Short Fixed Terms (90 Days or Less)

Section 7 of the RTA has a special rule: if a fixed-term tenancy is granted for 90 days or less, it does not automatically convert to a periodic tenancy at expiry. The tenancy simply ends on the agreed date, provided the parties don't extend it beyond 90 days or create consecutive short agreements to circumvent tenant protections.

This applies to genuine short-term arrangements — for example, providing temporary accommodation during renovations.

Tenant's Right to Renew

If the tenancy agreement contains an explicit renewal clause giving the tenant a right to renew, the tenant can exercise it by notifying you in writing at least 21 days before expiry. You can't override a contractual renewal right with a non-continuation notice.

Check your agreement before assuming you can end the tenancy at term.
