42 day notice NZ landlord: count the service time first

A 42-day notice is not the normal shortcut for ending every periodic tenancy in New Zealand.

As at 24 June 2026, Tenancy Services says landlords can end a periodic tenancy with 90 days' written notice without giving a reason, provided the notice is not retaliatory.

The 42-day route is narrower. It applies only for specific reasons, such as the owner or a family member needing the property as their main residence, the property being needed for employees or contractors where that use was clearly stated, or an unconditional sale requiring vacant possession.

The practical trap is this: the notice clock does not simply start when the landlord presses send. The clock starts the day after the notice is received, and service time can move that received date.

This guide is general information for NZ landlords, not legal advice. Use Tenancy Services, the official notice templates, and a lawyer or tenancy adviser for your specific situation.

When can a landlord use a 42-day notice?

A 42-day notice can apply when the landlord is ending a periodic tenancy for one of the allowed reasons listed by Tenancy Services.

Those reasons are:

• the owner, or a family member, needs the property as their main residence within 90 days of the tenancy ending and will remain there for at least 90 days
• the property is usually used by employees or contractors of the landlord, or was acquired for that purpose, that was clearly stated in the tenancy agreement, and the landlord needs the property for them
• the property has been sold under an unconditional sale and purchase agreement that requires vacant possession

If the landlord gives less than 90 days' notice, the reason must be included in the notice.

If none of those reasons applies, do not treat 42 days as the default. Check the current Tenancy Services guidance before acting.

When is 90 days the safer default?

Tenancy Services says landlords can end a periodic tenancy with 90 days' written notice without giving a reason, as long as the notice is not retaliatory.

That means 90 days is the general no-reason notice period for a periodic tenancy.

The shorter 42-day period depends on the reason. If the reason is wrong, missing, unsupported, or not recorded, the landlord may end up with a notice problem rather than a solved tenancy problem.

For a small landlord, that can create practical cost:

• the end date may be disputed
• the final inspection may need to move
• sale settlement or owner move-in plans may get tighter
• rent, bond, cleaning, access, and maintenance timing may all need rework
• the landlord may need advice or a Tenancy Tribunal process

The key point is not to guess the shortest date. The key point is to choose the correct notice pathway and keep the evidence with the tenancy.

What must every notice include?

Tenancy Services says every notice to end a tenancy must be in writing.

It must also:

• give the address of the tenancy
• give the date when the tenancy is to end
• be signed by the person giving the notice

For a 42-day landlord notice, include the reason for ending the tenancy. Use the official Tenancy Services template rather than building the notice from memory.

Keep a copy of:

• the final notice
• the reason relied on
• the official template used
• the date and method of service
• proof of delivery or sending
• the date the notice is treated as received
• the calculated tenancy end date
• any tenant replies

That record matters if the date is later challenged.

Why service time changes the date

Service time is the delay between sending a notice and the law treating the other person as having received it.

Tenancy Services gives different service-time rules depending on how the notice is delivered.

For notices other than family-violence withdrawal notices:

• handed over in person: received immediately
• left in the letterbox or clearly attached to the door: received 2 working days after delivery
• posted to the address or PO box: received on the fourth working day after posting
• sent to the electronic address for service after 5pm: received on the next working day
• sent to the electronic address for service before 5pm: received on that same day

The notice period starts the day after the notice is received.

That means a 42-day notice is not simply "send today, count 42 days". You need to know the service method, service time, received date, and first day of the notice period.

A simple service-time workflow

Before sending a landlord notice, run a short workflow.

1. Confirm the tenancy type. Fixed-term and periodic tenancies have different rules. Do not use a periodic-tenancy notice logic for a fixed-term problem.

2. Confirm the reason. If you want to use 42 days, match the reason to the official Tenancy Services list and keep the supporting record.

3. Use the official template. Do not rewrite a notice from an old email or a saved document unless you have checked it against the current template.

4. Choose the service method. Use an address for service or electronic address for service that is listed for the tenancy.

5. Add service time. Work out when the notice is treated as received, then start the notice period the next day.

6. Record the end date. Save the calculation, not just the final date.

7. Plan the end-of-tenancy steps. Final rent, utilities, inspection, cleaning, maintenance, keys, abandoned goods, and bond refund all need their own next action.

The workflow is simple, but it should not live only in the landlord's head.

Where Keel fits

Keel does not decide whether a landlord can end a tenancy, replace Tenancy Services, or give legal advice.

Keel helps with the operating layer around the decision.

A landlord can keep the tenancy record, notice reason, service method, received date, end date, tenant replies, final-inspection notes, maintenance follow-up, and bond tasks attached to the rental.

That matters because ending a tenancy is not one action. It is a chain of dates, evidence, tenant messages, and follow-up tasks.

If that chain sits across texts, email, calendar reminders, downloaded PDFs, and memory, the landlord is more likely to lose context at the exact point the date matters.

The takeaway

For a NZ landlord, a 42-day notice is a specific pathway, not a default shortcut.

Before you send one, check:

• is the tenancy periodic?
• does the reason fit the official 42-day list?
• does the notice include the required details?
• have you used the current template?
• how will the notice be served?
• when is it treated as received?
• when does the notice period actually start?
• what evidence and follow-up tasks need to stay with the tenancy?

The expensive mistake is not only choosing the wrong number of days. It is losing the record that proves how the date was chosen.

If you want tenancy dates, documents, tenant replies, approvals, and follow-up tasks kept in one operating flow, see how Keel works for landlords.
