New Zealand’s housing and lending market has taken a sharp and unexpected turn as of 26 March 2026.
Even though the Official Cash Rate (OCR) remains at 2.25%, major banks have started raising mortgage rates again. This is confusing many borrowers and buyers.
So what is really happening?
Let us break it down in simple terms, with real numbers, bank data, and what you should actually do next.
The key story is simple:
👉 Banks are increasing mortgage rates
👉 But the Reserve Bank has NOT increased the OCR
This means:
This is a major shift in direction.
Here is a clean comparison across major banks so readers can actually use this:
| Bank | 1-Year | 2-Year | 3-Year | 5-Year | Floating |
|---|---|---|---|---|---|
| ANZ | 4.59% | 5.09% | 5.39% | 6.19% | 5.79% |
| ASB | 4.59% | 5.09% | 5.39% | 5.69% | 5.79% |
| BNZ | 4.59% | 4.89% | 5.29% | 5.79% | 5.84% |
| Kiwibank | 4.59% | 4.89% | 5.35% | 5.89% | 5.75% |
| Westpac | 4.59% | 5.19% | 5.29% | 5.59% | 5.89% |
| TSB | ⭐ 4.39% | ⭐ 4.69% | ⭐ 4.99% | ⭐ 5.29% | 5.79% |
| Co-op Bank | 4.59%* | 4.89%* | 5.10%* | 5.40%* | ⭐ 4.99% |
👉 Estimated rates where applicable
Let me be blunt. Most people miss this:
👉 If you are not comparing beyond big banks, you are losing money.
This is where most people get it wrong.
It is NOT about NZ alone.
| Rate Type | Jan 2026 | March 2026 |
|---|---|---|
| 1-Year Swap | 2.65% | 3.15% |
| 2-Year Swap | 2.80% | 3.50% |
| 3-Year Swap | 3.10% | 3.93% |
👉 This is the real driver behind your mortgage rate.
Let us make this real.
If you have a $500,000 mortgage:
👉 This is where people start feeling pressure.
The market is not bouncing back as expected.
| Indicator | Status |
|---|---|
| House Prices | +2% to +5% forecast |
| Buyer Demand | Weak to moderate |
| Construction | Declining |
| Investor Activity | Slowing |
👉 Translation: This is NOT a strong market.
Now the important part. Not theory. Action.
👉 Property is no longer the easy win.
Look at Green Loans
| Bank | Offer |
|---|---|
| ANZ | 1% loan for eco upgrades |
| ASB | 1% Better Homes loan |
| BNZ | Low-rate sustainability loans |
👉 This is one of the cheapest borrowing options right now.
Let us not sugarcoat this.
New Zealand is entering a new phase of uncertainty.
This is bigger than just mortgage rates.
This is about:
👉 Cost of living
👉 Housing affordability
👉 Financial stability of families
And honestly, many people are not prepared for this shift.
If you take only one thing from this article, take this:
👉 Do NOT assume rates will stay low
👉 Do NOT trust just one bank
👉 Do NOT delay decisions if your loan is due
Because the easy money phase is over.
