42 Day Notice NZ Landlord: Selling, Moving In, and the Rules You Can't Ignore

The 42-day notice gives New Zealand landlords a faster way to end a periodic tenancy than the standard 90-day route — but it only works when specific statutory conditions are met. Use it incorrectly and the Tenancy Tribunal will void the notice, leaving you months behind schedule and potentially facing exemplary damages.

The Three Grounds for a 42-Day Notice

Since 30 January 2025, Section 51(2) of the Residential Tenancies Act 1986 allows landlords to issue 42 calendar days' notice to end a periodic tenancy under three specific grounds:

1. Unconditional sale with vacant possession (s 51(2)(c))

The sale and purchase agreement must be fully unconditional, and the contract must require the vendor to deliver vacant possession at settlement. You cannot issue a 42-day notice because the property is listed, because you've accepted a conditional offer, or because you're planning to sell. The contract has to be done — unconditional, signed, requiring vacant possession.

2. Owner or family occupation (s 51(2)(a))

The owner or an immediate family member must intend to move into the property as their main residence within 90 days of the tenancy ending, and stay for at least 90 continuous days. "Immediate family" means parents, spouse or partner (including civil union and de facto), children, or spouse's parents.

3. Employee or contractor accommodation (s 51(2)(b))

The dwelling must be customarily used for employees or contractors, and the tenancy agreement must state this. This ground is uncommon outside rural and institutional settings.

Every 42-day notice must explicitly state which ground applies. Unlike the 90-day notice, you can't leave the reason blank.

The Trust Ownership Trap

If the property is owned by a family trust or a company, the owner-occupation ground doesn't work. A trust or company can't physically live in a property, so it can't satisfy the requirement that "the owner" will occupy it as their principal residence. This catches a lot of landlords — New Zealand has a high rate of trust ownership for rental properties.

If you hold the property through a trust or company and need vacant possession, your options are:

• 90-day no-cause notice — no ownership-type restriction
• 42-day sale notice — if you have an unconditional sale agreement requiring vacant possession (the sale is made by the trust/company, but the vacant-possession requirement is contractual, not about personal occupation)

Issuing a 42-day owner-occupation notice on a trust-owned property and getting challenged at the Tribunal is a worst case: the notice is voided, you may face exemplary damages, and you've lost 42 days.

Calculating the End Date

The date calculation follows the same service deeming rules as any other notice under the RTA:

• Hand delivery: deemed received same day
• Letterbox: deemed received 2 working days later
• Post: deemed received 4 working days later
• Email (to a designated address for service): same day if before 5:00 PM, next working day if after

Day one of the 42 calendar days is the calendar day after deemed receipt.

Example: You place a 42-day sale notice in the tenant's letterbox on Thursday 1 October 2026. Working days: Friday 2 October (day 1) and Monday 5 October (day 2) — deemed receipt is Monday 5 October. Day one starts Tuesday 6 October. The earliest lawful end date is Monday 16 November 2026.

Get this wrong and the notice fails. The Tribunal doesn't grant extensions for miscalculation.

What If the Sale Falls Through?

Once you've served a 42-day notice, you can't unilaterally withdraw it. If the sale collapses — maybe the purchaser backs out of what was an unconditional contract — you need either the tenant's written agreement to withdraw the notice, or a consent order from the Tenancy Tribunal under Section 51(7).

The tenancy still ends on the stated date unless you take one of those steps. And if you served a 42-day notice on the sale ground but no sale actually existed, the notice was invalid from the start.

Consequences of a Fraudulent 42-Day Notice

If a landlord issues a 42-day notice claiming owner occupation and then doesn't move in within 90 days (or doesn't stay for 90 days), the former tenant can apply to the Tribunal. If the stated reasons were found to be false, the landlord faces:

• The notice being declared invalid
• Exemplary damages
• Potential compensation for the tenant's relocation costs

The Tribunal takes these seriously. Don't issue a 42-day notice unless you genuinely meet one of the three statutory grounds.

When to Use 42 Days vs 90 Days

The 42-day notice saves you 48 days — significant when you're working against a settlement date. But it requires proof of your ground and carries more legal risk if challenged. The 90-day no-cause notice is simpler (no reason needed, no evidence required beyond proper service), but takes longer.

If you're selling with an unconditional contract that already has a settlement date, the 42-day notice is built for exactly that scenario. If you just want flexibility and aren't in a rush, the 90-day notice is the safer route.
