What is the OCR, and what just happened
The Official Cash Rate (OCR) is the interest rate the Reserve Bank of New Zealand charges on overnight loans to commercial banks. It's the main lever the Reserve Bank has to influence inflation — nudge it up, and borrowing gets more expensive across the economy; nudge it down, and borrowing gets cheaper.
At its latest Monetary Policy Statement, the Reserve Bank's committee voted to lift the OCR by 25 basis points, from 3.25% to 3.50%. It's the first hike after a run of cuts through 2025, when the OCR was lowered to support a soft economy.
The OCR vs average mortgage rates
The OCR sets the direction — floating and short-term fixed mortgage rates tend to follow within weeks. Hover the chart for exact figures each quarter.
Why the Reserve Bank raised it
Rate decisions come down to balancing two risks: an economy running too hot (pushing prices up faster than the Reserve Bank's 1-3% inflation target) or too cold (rising unemployment, weak spending). Recent data showed inflation ticking back above the top of that band, driven by a mix of import costs and stronger domestic demand than expected — enough for the committee to conclude that a small hike now was cheaper than a bigger one later.
"One 25-point move isn't a crisis — it's a course correction. The bigger question is whether it's the first of several, or a one-off."
What it means for your mortgage
If you're on a floating rate, expect your bank to lift it within days — floating rates move almost in lockstep with the OCR. If you're fixed, nothing changes until your current term rolls off; but whatever rate you refix onto will likely be higher than it would have been before this hike.
Roughly speaking, each 0.25 percentage point rise costs an extra $0.25 in interest per $100 of mortgage per year. Here's what that looks like on some common loan sizes:
| Mortgage balance | Extra interest / year | Extra cost / week |
|---|---|---|
| $400,000 | $1,000 | ≈ $19 |
| $600,000 | $1,500 | ≈ $29 |
| $800,000 | $2,000 | ≈ $38 |
Approximate extra interest only, assuming the full 0.25pt move is passed through to your rate. Your actual repayment change depends on your loan's term, structure and how much of it is fixed vs floating — run your own numbers in the mortgage payment calculator below.
What it means for savings and term deposits
It's not all bad news. Banks typically lift term deposit and savings account rates within days to weeks of an OCR hike too, since the same wholesale funding costs that push mortgage rates up also make it more attractive for banks to compete for your deposits. The pass-through isn't always dollar-for-dollar, and shorter terms tend to move faster than long ones — so it's worth shopping around before you roll over a maturing term deposit.
What it means for prices and the wider economy
Higher rates cool the economy by making borrowing more expensive, which tends to slow spending on big-ticket items like houses and cars, ease pressure on prices, and — over time — bring inflation back toward target. The trade-off is that it also makes life harder for anyone with debt, and can weigh on business investment and hiring if rates stay elevated for long.
Economists will now be watching upcoming inflation and employment data closely to see whether this is a one-off adjustment or the start of a longer tightening cycle.
What you can do now
- Check your mortgage structure. If a big chunk of your loan is floating or about to come off a fixed term, model the new rate in the mortgage payment calculator so there are no surprises.
- Revisit your budget. An extra $20-40 a week in mortgage interest is real money — see how it fits using the monthly budget calculator.
- Shop your savings rate. Don't assume your bank's "loyalty" rate is competitive — compare term deposit rates before renewing.
- Don't panic-fix. Locking in a long fixed term the day rates rise isn't automatically the right move — compare terms with the refix / refinance calculator first.

Frequently asked questions
The Official Cash Rate is the interest rate the Reserve Bank of New Zealand charges on overnight loans to commercial banks. It's the main lever the Reserve Bank uses to influence inflation — when it moves, floating mortgage rates, savings rates and business lending rates tend to follow within weeks.
No. If you're on a fixed rate, your repayment stays the same until your current fixed term ends. The OCR mainly affects floating rates straight away, and new fixed rates offered to borrowers refixing or taking out a new loan.
Generally yes. Banks typically lift term deposit and savings account rates within days to weeks of an OCR hike, though the pass-through isn't always dollar-for-dollar and varies by bank and product.
