NZ Rent Increase Guide vs Free Tenancy Services Form: What the Form Does Not Cover
If you are choosing between the free official Tenancy Services rent increase notice form and a paid compliance guide, here is what matters: Form T190 is an official MBIE template you can use. The Act requires written notice with specified content but does not require a rigid form. A paid guide does not replace the notice; it fills the gap between preparing it and checking it correctly.
The question is whether that gap exists for you. For most self-managing landlords serving their first or second increase, it does.
What the Free Form Gives You
The official rent increase notice template from Tenancy Services (Form T190, revised March 2025) has fields for the required notice details. It is free; the Act requires the notice to include specified information but does not require a rigid form.
The notice must include:
- The legal names of the landlord(s) and named tenant(s), and the property address
- The current and proposed rent amounts
- The exact date the increase takes effect
- The landlord's or authorized agent's signature and landlord contact details
- The service method
The template also has a field for the date the notice was given.
The template does not calculate anything or check whether your dates and service method are valid. It trusts you to enter the correct details.
What the Free Form Does Not Do
| Compliance requirement | Free form | Paid guide |
|---|---|---|
| 12-month frequency audit | Not mentioned — assumes you know the date of the last increase | History Log worksheet with structured date verification |
| 60-day notice period | Blank "date given" field — you calculate the window | Step-by-step calendar calculation with worked example |
| Service delivery buffer | Lists delivery options and service-day allowances, but does not calculate the effective date | Buffer Calculator for each method (post: +4 working days, door: +2 working days, email or text to an address for service: same working day before 5 p.m., next working day after 5 p.m.) |
| Fixed-term clause check | Includes a fixed-term note, but does not check your specific agreement | Decision Tree for checking whether your agreement permits mid-term review |
| Bond top-up calculation | Separate process, no guidance on the form | Worksheet calculating proportional top-up within the 4-week statutory maximum |
| Market rent evidence | Not part of the form or the Tenancy Services guidance | Evidence Log for compiling comparable listings and MBIE Market Rent Tool data to present in a Tribunal challenge |
| Field verification | No validation — you submit what you wrote | Checklist walking through the required notice details before it goes out |
The MBIE Market Rent Tool exists on the Tenancy Services website and shows suburb-level rental data. But it does not tell you how to compile that data into structured evidence for a Tribunal hearing. The Tenancy Tribunal pages explain how to file an application and what the hearing process looks like, but not how to prepare your market rent case or verify your notice compliance before you serve it.
Where Mistakes Actually Happen
The form itself is simple, but the errors that invalidate a rent increase happen before you pick it up:
Miscounting the 12-month window. If your last increase took effect on 15 March 2025, your next increase cannot take effect before 15 March 2026. A landlord who counts from the date they served the notice (not the effective date) can land inside the 12-month window without realising. The Tribunal will void the increase.
Forgetting the service buffer. Sixty days' notice means 60 days from the date the tenant receives the notice, not from the date you post it. If you send the notice by standard post on 1 June, add four working days for deemed delivery; an effective date of 1 August would be four days too early. The service allowance is shorter for other methods, but you still need to count from deemed receipt. The form lists service-day allowances but does not calculate the date for you.
Missing the fixed-term clause. If your tenancy is on a fixed-term agreement and the agreement does not contain a rent review clause, you cannot increase the rent until the fixed term expires — even if 12 months have passed. The form does not ask what type of tenancy you have.
These are not obscure edge cases. On r/PersonalFinanceNZ and r/newzealand, tenants regularly challenge rent increases on exactly these grounds: short notice, wrong effective date, no review clause in a fixed-term tenancy.

Who Should Use the Free Form Alone
You probably do not need a guide if:
- You have served multiple valid rent increases before and understand the 12-month rule, service buffer, and fixed-term clause from experience
- You are on a periodic tenancy (no fixed-term clause issue) and you are serving by hand delivery (no postal buffer to calculate)
- Your property manager handled previous increases and you have clear records of every effective date
Who This Is For
- Self-managing landlords serving their first rent increase in New Zealand
- Accidental landlords who inherited a property or are renting out a former home
- Anyone who looked at the free form and thought "what date do I actually put here?"
- Landlords approaching a fixed-term expiry who are not sure whether the agreement allows a mid-term review
Who This Is NOT For
- Experienced landlords who have been through the process multiple times and know the calculations
- Anyone who already uses myRent or a property manager — those services handle the date calculations for you
- Landlords looking for legal advice on what rent to charge (no guide decides that — you set the market rent)
The Rent Increases in New Zealand guide exists for the gap between having the official form and knowing what to write on it. If that gap does not apply to you, the free form is all you need.
Frequently Asked Questions
Do I still need the official Tenancy Services form if I buy a guide?
You still need to serve a written notice with all required information. Form T190 is Tenancy Services' official template, but the Act does not require a rigid form. The guide does not replace the notice; use T190 or another written format that meets the requirements.
Is the free Tenancy Services form legally sufficient on its own?
Form T190 is an official template, not a required statutory form. A written notice can be valid if it includes the required information and meets the timing and service rules. The template does not help you calculate those dates; it trusts you to get them right.
What is the most common mistake the free form does not prevent?
The service delivery buffer. Landlords post the notice and count 60 days from the posting date, but the 60-day clock starts from deemed receipt — which is four working days later for standard post. A notice that looks like it meets the deadline by calendar counting can be legally short by several days.
Can I use the MBIE Market Rent Tool instead of a market rent evidence log?
The MBIE tool shows suburb-level rent quartiles. It is a useful starting point. If the tenant challenges your increase at the Tenancy Tribunal, comparable local evidence such as listings and valuation reports can help show the market rent. The guide's Market Rent Evidence Log helps organise that information for presentation to the Tribunal.
How much does the Tenancy Tribunal charge if the tenant challenges my increase?
Filing fees are $20–$50 NZD. Hearings are designed for self-represented parties — you do not need a lawyer. But an invalid notice means the Tribunal orders you to refund any rent collected at the higher rate, so the real cost of a mistake is the lost income, not the filing fee.
