Rent Reviews in New Zealand: Getting the Balance Right

A rent review and a rent increase are not the same thing. It is easy to assume that reviewing the rent means putting it up, but a good review sometimes concludes that the right move is to hold the rent where it is. Over the past 12 to 18 months, with a subdued rental market across much of New Zealand, that has been the honest answer for a lot of properties.

This article explains how to think about a rent review as a landlord: what the rules allow, why an increase is not always possible, why a review still matters even when the rent stays flat, and how to weigh a modest increase against the risk of losing a good tenant.

What are the rules on rent increases in New Zealand?

In short, rent can only be increased once every 12 months, and not within the first 12 months of a tenancy. The tenant must be given at least 60 days’ written notice, stating the new rent and the date it starts. There is no legal cap on the amount, but if the rent ends up well above what similar properties are charging, the tenant can challenge it at the Tenancy Tribunal. In practice, that means rising costs on their own do not justify an increase the market will not support.

Those are the mechanics, and Tenancy Services (tenancy.govt.nz) sets out the full rules, including the limited situations where an increase can be agreed sooner. But the rules are the easy part. The harder question is whether an increase is the right call at all.

Why a rent increase may not be the right move

There are several good reasons an increase might not make sense at a given moment, and a proper review considers all of them.

The local market may not support it. Rents vary by region, suburb and property type. If comparable properties are achieving similar or lower rents, pushing above the market makes yours harder to let.

Tenants may have more choice. When there is plenty of available stock, tenants have options, and landlords need to be realistic about what the market will bear.

The property may already be at market. Not every property has room to move. If the current rent is already consistent with comparable homes, holding it is the sensible recommendation.

A good tenant is worth protecting. A long-term tenant who pays on time, looks after the place and communicates well is genuinely valuable. The cost of losing them has to be weighed against any proposed increase.

The timing may be wrong. Seasonality and current demand matter. Sometimes waiting for conditions to improve beats forcing an increase at a weak moment.

The property may need investment first. If presentation or condition is holding the rent back, improving the property may be a better path to a higher rent than simply asking for more.

Underlying all of this is a basic truth. However much your own costs have risen, the market decides what tenants are willing and able to pay.

No increase does not mean no review

Even when the recommendation is to hold the rent, the review is still worth doing. It confirms where your property sits against comparable rentals right now, and it flags what has changed since the last review. It can also surface an opportunity to revisit the rent later, once the market lifts, the tenancy changes or improvements are made.

That is why a rent review is better understood as an ongoing conversation than as an annual exercise in pushing the number up. The point is to keep the property positioned correctly, not to raise the rent on a calendar.

When an increase is appropriate

When the market does support an increase, it should be recommended. The judgement rests on comparable properties, current demand, the condition and features of the home, and the strength of the existing tenancy.

The goal is not the highest advertised rent. It is a rent that is fair, competitive and sustainable. Consider a simple example. A 20 dollar a week increase looks like 1,040 dollars a year. But if it prompts a good tenant to leave and the property then sits empty for three weeks while you re-let it, the lost rent, the re-letting costs and any work to ready it for a new tenant can wipe out that gain and more. Chasing the headline number can cost you the real return.

It is about the whole return, not just the rent

Rental income is one part of your investment return, not the whole of it. A property that performs well also relies on minimising vacancy, retaining good tenants, keeping up maintenance, responding to problems quickly, staying competitive, understanding the market and making decisions on evidence rather than assumption.

A rent review that ignores those factors and fixates on the weekly figure is not really doing its job. The number has to serve the bigger picture.

Have the conversation

A good rent review gives you an honest read on where your property sits, lays out the options, and, if an increase is warranted, manages the conversation with your tenant professionally. Sometimes that means recommending an increase, sometimes holding steady, and sometimes identifying an improvement that would lift the rent later.

If you have not had a recent review, it is worth getting one. A clear picture of your property's current market position costs you nothing and often changes how you think about the next 12 months. You can start with a free rental appraisal, or talk to your Rent Shop property manager about where your rent sits today.

Frequently asked questions

How often can a landlord increase rent in New Zealand? Once every 12 months, and not within the first 12 months of a tenancy. You must give at least 60 days’ written notice. Tenancy Services sets out the full rules, including the limited situations where an increase can be agreed sooner.

Does a rent review always mean a rent increase? No. A review assesses where your rent sits against the market. Sometimes the right outcome is to hold the rent, particularly in a soft market or with a strong long-term tenant.

How is market rent worked out? By looking at what comparable properties nearby are actually achieving, adjusted for your property's specific features, condition and the current level of demand.

Is it worth a small increase if it risks losing a good tenant? Often not. A modest weekly gain can be outweighed by even a few weeks of vacancy plus re-letting costs. The value of a reliable tenant should be part of the calculation.

What if my costs have gone up but the market has not? Unfortunately your costs do not set the rent. The market does. If an increase is not achievable, the review can instead flag improvements or a better time to revisit.
