How to Increase Rent in NZ Without a Property Manager or Lawyer

You do not need a property manager or a lawyer to increase the rent on your New Zealand rental property. The process is statutory — the Residential Tenancies Act 1986 (Sections 24 and 25) sets out exactly what is required, and the Tenancy Tribunal is designed for self-represented parties if a dispute arises. What you need is accuracy: five calculations, done in the right order, with no date errors.

Here is the process from start to finish.

Step 1: Verify the 12-Month Rule

Under Section 24(1)(d) and (e), rent cannot be increased within 12 months of the tenancy start date or the effective date of the last increase. The 12-month window runs from the effective date of the last increase — not from the date you served the notice or the date the tenant acknowledged it.

If the last increase took effect on 1 April 2025, the earliest your next increase can take effect is 1 April 2026. If you have never increased the rent, the window runs from the start date of the tenancy.

Find the effective date of your last increase. If you do not have records, check your bank statements for the date the new rent amount first appeared. Getting this date wrong — even by a single day — makes the entire notice invalid.

Step 2: Check Your Fixed-Term Clause

If your tenancy is periodic (rolling, month to month), skip to Step 3.

If your tenancy is on a fixed term, check the tenancy agreement for a rent review clause. Under Section 24(1)(g), you cannot increase rent during a fixed-term tenancy unless the agreement specifically permits it. Not all fixed-term agreements include one.

Look for wording that says "the rent may be reviewed during the fixed term" or "the landlord may increase the rent by giving notice." If no such clause exists, the rent remains fixed for the entire term. After the tenancy converts to periodic, standard rent-increase notice rules apply.

If a rent review clause exists, note whether it specifies a particular review date or allows review at any time during the term. This affects your timing.

Step 3: Calculate the 60-Day Notice Period

Section 24(1)(c) requires at least 60 days' written notice before the increase takes effect. The 60 days are calendar days, not working days.

But — and this is where most self-managed increases go wrong — the 60-day clock starts from the date the tenant receives the notice, not from the date you send it.

If you hand-deliver the notice and the tenant accepts it, delivery is immediate. If you post it, you must add the statutory delivery buffer: the deemed receipt date for standard mail is four working days after posting (Section 136 of the Residential Tenancies Act, as amended in March 2025). If you attach the notice to the front door or place it in the letterbox, deemed receipt is two working days later.

Worked example: You want the increase to take effect on 1 September 2026. The 60-day notice period must begin on 3 July, so the tenant must receive the notice by 2 July 2026. If you are posting it, add four working days: post by Friday 26 June 2026.

One day short and the notice is void. The tenant can ignore it, and if you have already collected the higher rent, the Tribunal can order you to refund it.

Step 4: Prepare a Written Notice and Serve It

MBIE's Form T190 ("Notice of rent increase") is an official template you can use; the Act does not require a rigid form. Your written notice must include:

• The landlord and tenant names and the address of the premises
• The current weekly or fortnightly rent
• The new weekly or fortnightly rent
• The date the increase takes effect
• The landlord's or authorized agent's signature and landlord contact details
• The service method
• The date the notice was given

Fill in every applicable field. Do not leave the "date given" blank and fill it in later — the date must be the actual date of service.

Serve the notice using a method allowed under Section 136: hand delivery (have the tenant sign an acknowledgement), standard post (keep the posting receipt), electronic service to an address provided for service in the tenancy agreement, or attachment to the front door or placement in the letterbox (document with a dated photograph). For email or text, keep proof of transmission to the agreed address.

Keep proof of service. If the tenant later disputes the notice, your proof of service and the correctly calculated dates are your defence.

Step 5: Handle the Bond Top-Up (If Applicable)

After a rent increase, you may ask the tenant to increase the bond to match the new rent level. The maximum bond is four weeks' rent (Section 18). If the current bond is less than four weeks of the new rent, you can request a top-up.

The top-up amount is the difference between the current bond and four weeks of the new weekly rent. The tenant pays this separately from the rent increase. Lodge the additional bond with Tenancy Services within 23 working days.

You cannot require the tenant to pay both the bond top-up and more than two weeks' rent in advance at the same time (Section 23 limits advance rent to two weeks).

When You Might Actually Need Professional Help

You do not need a property manager or a lawyer for a standard rent increase. But there are two situations where professional input has value:

The tenant has filed a Tribunal application challenging the increase under Section 25. You can represent yourself — Tribunal hearings are informal and designed for non-lawyers. But if the dispute involves a complex fixed-term clause, ambiguous service history, or a counter-claim for Healthy Homes non-compliance, a property law consultation (not ongoing management) may be worth the one-off fee.

You cannot locate records of the previous increase. If your tenancy dates are unclear and you risk breaching the 12-month rule without knowing it, a one-off review of your tenancy file by a property manager or a community law centre can establish the timeline. Citizens Advice Bureau and Community Law Centres offer free guidance — though they are primarily tenant-focused, they can point you to the right records.

For everything else — the date calculations, the form, the service method, the bond top-up — the law is specific enough that a self-managing landlord can follow the process without professional intermediaries.

The Rent Increases in New Zealand guide consolidates all five steps into a single compliance system with worksheets, worked examples, and a verification checklist. It is built for landlords doing exactly this: handling the increase themselves, correctly, the first time.

Frequently Asked Questions

Can I serve a rent increase notice by text message?

Yes, a written notice can be served electronically, including by text, if the electronic address is provided as an address for service in the tenancy agreement. Section 24 requires written notice with the required information; T190 is the official MBIE template, not a mandatory form. Hand delivery, standard post, and letterbox or door delivery are other service options.

What happens if the tenant just ignores my notice?

If the notice is valid — required written details, correct dates, correct service — the tenant is legally obligated to pay the new rent from the effective date. If they continue paying the old amount, you can apply to the Tenancy Tribunal for an order requiring payment of the difference. If the notice is invalid, the tenant is entitled to ignore it.

Do I need to justify the amount of the increase?

No. There is no rent cap or guideline rent system in New Zealand. You can increase the rent to any amount, provided the notice is valid. However, if the tenant applies to the Tenancy Tribunal under Section 25, the Tribunal can assess whether the new rent substantially exceeds the market rent for comparable properties. This is why having a market rent evidence log — comparable listings, MBIE data — strengthens your position.

Can I increase the rent by any amount?

Legally, yes — New Zealand has no rent control or maximum percentage increase. Practically, a large increase risks the tenant applying to the Tribunal for a market rent assessment, or simply giving notice and leaving. Most self-managing landlords increase in line with market movement to avoid both outcomes.

Is there a penalty for serving an invalid notice?

The notice itself is void — the tenant can ignore it and keep paying the existing rent. If you collect the higher amount despite an invalid notice, the Tribunal can order reimbursement and may impose exemplary damages. There is no criminal penalty, but the lost income from a voided notice (and the time to re-serve correctly) is the real cost.
