The Reserve Bank of New Zealand has increased the Official Cash Rate (OCR) by another 25 basis points, taking it from 2.50% to 2.75%.
It follows the July increase from 2.25% to 2.50% and confirms the shift we’ve been discussing throughout our recent OCR updates.
Earlier in 2026, the conversation was largely about how quickly interest rates might fall.
That has changed.
Annual inflation has reached 4.1%, driven largely by higher fuel prices, and the Reserve Bank has responded by strengthening monetary policy again.
For homeowners, first home buyers and property investors, this doesn’t mean you should panic or immediately lock your mortgage into the longest available fixed term.
It does mean it’s worth understanding how the changing rate environment affects your mortgage, your repayments and your wider plans.
Concerned About Rising Rates?
If your mortgage is due to refix, you’re considering refinancing, or you’re simply unsure whether your current loan structure still suits you, now is a good time to review it.
At The Advice Group, we’ll help you understand your options and create a mortgage strategy around your circumstances, rather than trying to predict every move the Reserve Bank makes.
Why Did the Reserve Bank Increase the OCR to 2.75%?
The latest increase is about inflation.
Annual headline inflation has reached 4.1%, putting it above the Reserve Bank’s 1–3% target range.
A significant part of that increase has come from higher fuel prices following disruption to global oil markets.
That’s an important distinction.
Inflation excluding vehicle fuels was considerably lower at 2.9%, suggesting that the headline number doesn’t tell the entire story.
However, the Reserve Bank is concerned that this initial price shock could spread through the wider economy.
Higher fuel costs don’t only affect what you pay at the pump. They can flow through into:
- Freight and transport
- Food prices
- Business operating costs
- Household expenses
- Wider pricing decisions
The Reserve Bank has therefore increased the OCR now to reduce the risk of inflation becoming more persistent.
From 2.25% to 2.75%: How Quickly Has the Outlook Changed?
The change in direction becomes clearer when we look back over TAG’s OCR updates this year.
Earlier in 2026, the OCR was sitting at 2.25%.
By May, the Reserve Bank was warning that inflation pressures would require higher interest rates.
In July, it acted, increasing the OCR to 2.50%.
Now, in September, we’ve seen another 0.25% increase, taking the OCR to 2.75%.
In other words, the OCR has increased by 0.50 percentage points across the past two decisions.
That is why borrowers should be careful about basing long-term mortgage decisions on assumptions about where rates are “definitely” heading.
The outlook can change.
TAG Insight
We said it in our previous OCR update, and it continues to be relevant now:
The goal shouldn’t be to predict the market perfectly. It should have a mortgage strategy that works over different scenarios.
- If rates increase again, what happens to your repayments?
- If they stay around current levels for longer, does your structure still work?
- And if rates eventually fall, how much flexibility do you want to retain?
Those are much more useful questions than trying to pick the exact top or bottom of an interest-rate cycle.
What Does a 2.75% OCR Mean for Mortgage Rates?
An OCR increase does not automatically mean every mortgage rate increases by 0.25%.
This is particularly important for fixed mortgages.
Floating and Variable Mortgage Rates
Floating and variable rates are generally more directly influenced by changes in the OCR.
Following an OCR increase, lenders may review their floating mortgage rates and adjust them accordingly.
If a significant portion of your mortgage is floating, it’s worth understanding what any lender changes could mean for your repayments.
Fixed Mortgage Rates
Fixed mortgage rates are different.
They’re influenced by wholesale funding costs, swap rates and financial-market expectations about where interest rates are likely to go next.
Markets don’t wait for an OCR announcement.
If investors and banks expect the Reserve Bank to increase rates, some of that expectation may already be reflected in fixed mortgage pricing before the announcement happens.
That’s why choosing a mortgage term based solely on the OCR can be misleading.
What matters is what rates are actually available, how they’re expected to affect your repayments, and how the different options fit your circumstances.
Is Your Mortgage Due to Refix?
This is where the September announcement is especially relevant.
If your fixed mortgage term expires in the next 6–12 months, it’s worth starting the conversation early.
You don’t need to decide today.
But you should understand your options.
A mortgage review with The Advice Group can help you consider:
- Available fixed terms
- Fixed versus floating
- Whether splitting your lending may be appropriate
- Potential repayment changes
- Staying with your existing lender versus refinancing
- Your need for certainty and flexibility
- How your mortgage fits your wider financial goals
The right decision isn’t necessarily whichever option has the lowest advertised rate today.
It’s the option that makes sense for your household, cashflow and plans.

Should You Fix Your Mortgage Now?
There’s no universal answer.
An OCR increase can naturally make borrowers nervous about further increases, but that doesn’t automatically mean everyone should immediately fix for the longest possible term.
There are trade-offs.
A longer fixed term may provide greater repayment certainty but could reduce your flexibility when circumstances or interest rates change.
A shorter fixed term may provide more flexibility but additionally exposes you to another refix sooner.
Some borrowers may also consider splitting their mortgage over different fixed terms so the entire loan doesn’t come up for refix at the same time.
The appropriate approach relies on factors such as:
- Your budget
- Current mortgage structure
- Future income
- Plans to sell or move
- Ability to make additional repayments
- Appetite for interest-rate risk
- Need for certainty
That’s why personalised mortgage advice matters.
Not sure whether to fix, float or split your lending? Let’s look at the numbers and work through the options together.
Could the OCR Rise Again?
Yes, further increases remain possible.
The Reserve Bank has made apparent that the future OCR path is not predetermined.
That means another increase isn’t guaranteed.
Future decisions will depend on how inflation, economic activity and other conditions develop.
The Reserve Bank’s current outlook expects headline inflation to remain elevated through 2026 before returning to its 1–3% target band during 2027.
For borrowers, the takeaway isn’t that rates are guaranteed to keep rising.
It’s that uncertainty remains.
Rather than trying to guess the next OCR decision, consider how another increase would affect your own position.
What would another rate increase mean for you?
If you’re unsure, we can model different scenarios and help you understand what they could mean for your repayments and lending structure.
What Does the OCR Increase Mean for First Home Buyers?
If you’re trying to buy your first home, another OCR increase can feel like another obstacle.
Higher interest rates may affect:
- Potential mortgage repayments
- Borrowing capacity
- Bank serviceability calculations
- How much you could comfortably afford
- The repayment buffer you should allow for
But that doesn’t automatically mean you should put your plans on hold.
Perfectly timing both the housing market and interest rates is extremely difficult.
A better starting point is understanding your own position.
How much could you borrow?
More importantly, how much are you comfortable borrowing?
What would repayments look like at different interest rates?
And what lending structure could give you an appropriate balance between certainty and flexibility?

What Does the OCR Increase Mean for Property Investors?
For property investors, another increase makes cashflow planning particularly important.
If you have multiple loans or fixed terms expiring over the coming months, relatively small changes in mortgage rates can add up across a portfolio.
It may be worth reviewing:
- Upcoming refix dates
- Portfolio cashflow
- Loan structures
- Fixed-term exposure
- Interest-only arrangements where appropriate
- Refinancing opportunities
- Future acquisitions
A portfolio lending review isn’t necessarily about making changes immediately.
It’s about understanding where you’re exposed and making sure your structure still supports your longer-term investment strategy.

Don’t Focus Only on the Interest Rate
An OCR announcement naturally puts interest rates front and centre.
But your interest rate is only one part of your mortgage.
A refix or market change can also be a useful opportunity to ask:
- Is my mortgage structured efficiently?
- Am I using the right loan features?
- Could an offset or revolving credit structure suit me?
- Does my repayment frequency still make sense?
- Have my income or expenses changed?
- Could I repay my mortgage faster?
- Is my current lender still appropriate?
- Have my property or financial goals changed?
Sometimes the biggest opportunity isn’t finding a slightly lower rate.
It’s improving the way the overall mortgage works for you.
When Is the Next OCR Announcement in NZ?
The Reserve Bank’s next OCR decision is scheduled for 28 October 2026.
Between now and then, mortgage rates can still move.
Wholesale markets continually respond to inflation data, economic circumstances and expectations about future Reserve Bank decisions.
That means borrowers don’t necessarily need to wait until 28 October before reviewing their position.
If your mortgage is due for refix around this period, starting early gives you time to understand your options rather than making a rushed decision after the next announcement.
Frequently Asked Questions
The Official Cash Rate is 2.75%, following a 25-basis-point increase by the Reserve Bank in September 2026.
This follows the July increase from 2.25% to 2.50%.
The Reserve Bank increased the OCR in response to inflation pressures. Annual headline inflation reached 4.1%, with higher fuel prices playing a major role in the increase.
The Bank is seeking to prevent these price pressures from becoming more persistent across the wider economy.
Not necessarily.
Floating mortgage rates tend to be more directly influenced by OCR movements, whereas fixed mortgage rates are also affected by wholesale funding costs and expectations about future interest rates.
Different lenders may therefore respond differently.
It could, but another increase isn’t guaranteed.
The Reserve Bank has said the future OCR path is not predetermined. Future decisions will depend on inflation and wider economic conditions.
That depends on your circumstances.
Your decision should consider your budget, refix date, plans, need for repayment certainty, available rates and tolerance for future rate movements.
Not necessarily.
Fixed mortgage rates can move before an OCR decision as wholesale markets react to expectations.
If your mortgage is approaching a refix date, reviewing your options early can give you more time to make an informed decision.
The next Reserve Bank OCR decision is currently scheduled for 28 October 2026.
TAG’s Perspective: Don’t Let the Headlines Make Your Mortgage Decisions
The September OCR increase confirms just how quickly the interest-rate outlook can change.
Earlier this year, much of the discussion was about falling rates.
Since July, the Reserve Bank has increased the OCR twice, taking it from 2.25% to 2.75%.
Could rates rise again? Yes.
Could the Reserve Bank hold at its next meeting? That’s also possible.
And eventually, conditions will change again.
That’s why at The Advice Group, we’d rather help you build a strategy than try to sell you a prediction.
Your mortgage should be structured around your goals, your cashflow, your risk tolerance, and your plans.
