The OCR Went Up: What It Actually Means for NZ Landlords

On 8 July 2026 the Reserve Bank raised the Official Cash Rate to 2.5%, up from 2.25%. It had held at 2.25% through the February, April and May reviews, and this was the first increase since May 2023. Banks have been repricing fixed mortgage rates since, with Kiwibank joining the other majors in August.

If you own rentals, three things follow. Only one of them is about rent.

1. Your borrowing cost changes on a delay

The OCR is the overnight rate the Reserve Bank sets. It feeds into what banks pay for money, and from there into what they charge you. But it reaches landlords unevenly:

• Floating loans move quickly, usually within weeks.
• Fixed loans do not move at all until they come off fix. If you fixed for two years in 2025, nothing happens to you today.

That delay is the thing to plan around. The pain is not a single event, it is a schedule. Most landlords with more than one property have loans rolling off at different times, so the real question is which one reprices next and what the payment becomes at current rates.

Banks have also been raising advertised fixed rates ahead of any further OCR move, which is why commentary has focused on the rush to lift fixed pricing rather than on the OCR itself.

2. You cannot just pass it on

This is where landlords get into trouble, and it is worth being precise. Under section 24 of the Residential Tenancies Act 1986:

• Rent for a given tenancy can only be increased once every 12 months.
• You must give at least 60 days written notice. Not 90, which is a common and expensive misremembering of the periodic-tenancy termination notice.

Tenancy Services sets this out on its increasing rent page. Your mortgage repricing is not an exemption from either limit, and a tenant can challenge an increase that puts rent substantially above market for comparable properties.

So the honest position: an OCR rise changes your costs this year, and your rent can only respond on its own 12-month cycle, at market. If those two do not line up, the gap is yours to carry.

3. Rising rates and a soft market arrive together

The awkward part of this cycle is that borrowing costs are rising while prices are not. QV recorded average house prices falling 1.5% in the July quarter, and market commentary has described prices as stuck in a rut with lending flat.

For a landlord holding rather than trading, capital value moving sideways is survivable. It is the cashflow that decides whether you hold comfortably or not, which is why the arithmetic below matters more than the headlines.

What to actually do

1. Write down when each loan comes off fix. This is the single most useful thing, and most landlords cannot answer it from memory.
2. Model the repayment at current rates, not at the rate you are on. If a repricing turns a property cashflow-negative, you want to know months ahead, not on the day.
3. Check when each tenancy last had a rent increase. If it was more than 12 months ago and rent is below market, that is a lawful adjustment available to you with 60 days notice. If it was three months ago, it is not, whatever your bank did.
4. Get your deductible interest recorded properly. Mortgage interest on a rental is an expense; it needs to be captured per property to be claimed cleanly.
5. Do not defer maintenance to cover the gap. It is the most tempting lever and the most expensive one, because the duty to maintain the property in a reasonable state of repair under section 45(1)(b) does not soften when your costs rise.

A note on inflation

The OCR moves in response to inflation, which is measured by the Consumers Price Index published by Stats NZ. If you want to understand where rates are heading, that release is the thing to watch rather than any individual bank's advertised rate.

Keeping the numbers straight

RentManager records mortgage interest per property and feeds it into the IR3R-shaped rental income summary, so the effect of a repricing shows up in your reporting through the year instead of being reconstructed in April. Rent increase notices are generated with the correct 60-day period and the 12-month rule applied, and the last increase date is on the tenancy, so you can see at a glance which properties are actually eligible.

More guides are in the Landlord Hub.

Common questions

Can I raise the rent because my mortgage rate went up?

Not on demand. A rent increase for the same tenancy can only take effect once every 12 months, and you must give at least 60 days written notice under section 24 of the Residential Tenancies Act 1986. Your costs rising is not an exception to either rule, and the increase still has to be in line with market rent.

What is the OCR right now?

The Reserve Bank set the Official Cash Rate at 2.5% on 8 July 2026, up from 2.25% where it had sat through the February, April and May 2026 reviews. Check the RBNZ decisions page for the current figure, since it changes at each review.

Does the OCR change my mortgage rate immediately?

Only if you are on a floating rate. Fixed loans do not change until they come off fix, which is why the effect on landlords is staggered over a year or more rather than felt all at once. Banks have been lifting advertised fixed rates in anticipation.
