Will mortgage rates drop to 3% again?

Historical context of 3% mortgage rates

New Zealand mortgage rates have not consistently sat at 3% since the Reserve Bank of New Zealand’s OCR was slashed to emergency lows during the COVID-19 pandemic. In 2021, borrowers could fix a 1-year rate at around 2.5%, but that era ended when the OCR began rising in late 2021RBNZ monetary data. BNZ’s own 1-year fixed rate peaked at 7.35% in February 2024BNZ official blog.

For rates to return to 3%, the OCR would need to fall to levels not seen outside a severe recession. The OCR currently sits at a restrictive level, and while markets have priced in cuts, most major bank economists do not project a return to the sub-3% mortgage rates of 2021 within the next 12 monthsRBNZ monetary data.

Current forecasts for New Zealand mortgage rates

Analysts from ANZ and ASB have projected further OCR reductions through late 2025 and into 2026, which could push 1-year fixed rates toward 4% but not below that threshold RBNZ monetary data. BNZ’s own trajectory reflects this: the bank cut its 1-year rate by 10 basis points to 4.79% in August 20251News reporting, then to 4.49% by September 2025. The 3-year rate dipped to 4.99% in February 20261News reporting.

Bottom line: A return to 3% mortgage rates is not forecast by any major bank. BNZ borrowers should expect rates to stay above 4% for the foreseeable future. Those hoping for sub-4% rates: plan for at least 12 months of patience. Borrowers needing to fix now: shorter terms offer the best chance to ride the downward trend.
The trade-off

Waiting for a 3% rate means gambling with floating rates that are currently higher than most fixed terms. BNZ’s floating rate sits above 6%, so the cost of waiting can add up quickly for anyone not prepared to absorb that premium.

Comparing 2-year vs 5-year fixed rates at BNZ

As of the latest BNZ rate cuts in October 2025, the 2-year fixed rate dropped to 4.49%, while the 5-year rate stood at 4.99% — a gap of 50 basis points1News reporting. The difference reflects market expectations that rates will be lower in two years than in five.

Here is a direct comparison of the two options:

The pattern: shorter fixes cost less now, while longer fixes insure against future uncertainty.

Term BNZ rate (Oct 2025) Monthly payment on $500k Risk profile
2-year fixed 4.49% $2,793 Higher if rates rise, lower if rates fall further
5-year fixed 4.99% $2,967 Lower (locked in), but $174/month more expensive now

The implication: the 50-basis-point gap between these two terms is the price of certainty — and it may be worth paying if you cannot absorb rate risk.

Risk assessment for locking in longer terms

The key question is whether the current rate-cutting cycle has further to run. If the OCR drops another 75–100 basis points by mid-2026, a 2-year fix at 4.49% would be followed by refixing at potentially 3.75–4% — a meaningful saving. But if inflation proves stubborn and the OCR stalls, locking in 4.99% for five years looks like good insuranceMPA Magazine NZ.

Bottom line: BNZ borrowers with flexibility to absorb small rate movements: the 2-year fix at 4.49% is the better bet. Those who need payment certainty for a longer stretch: 5-year at 4.99% locks in a rate that, in historical context, is still below the 10-year average. There is no universal “right” answer — it depends on your tolerance for rate risk.
What to watch

BNZ’s 5-year rate fell by 0.40% in the October 2025 cut — the largest single reduction among all terms. That suggests the bank is betting on sustained lower rates, but it also means the 5-year rate has more room to rise if the outlook shifts.

What is the current fixed home loan rate at BNZ?

BNZ 1-year fixed rate (4.49%)

BNZ’s 1-year fixed rate of 4.49%, effective from September 2025, is the standout headline rate in the bank’s current lineup. It represents a nearly 40% drop from the February 2024 peak of 7.35%BNZ official blog. The rate is available to new customers and existing borrowers eligible to refix.

BNZ 2-year, 3-year, 4-year, and 5-year fixed rates

Here is the full set of BNZ’s current advertised fixed rates as of the latest cuts:

The pattern: shorter terms are cheapest, with a slight step-up at 3 years before the 4- and 5-year terms climb further.

Fixed term Rate (p.a.) Effective date Change from previous
6 months 4.79% Oct 2025 Cut from 5.09%
1 year 4.49% Sep 2025 Cut from 4.79%
18 months 4.45% Oct 2025 Cut from 4.79%
2 years 4.49% Oct 2025 Cut from 4.89%
3 years 4.99% Feb 2026 Cut from 5.19%
4 years 5.19% Feb 2026 Cut from 5.55%
5 years 4.99% Oct 2025 Cut from 5.39% (40 bps)

The pattern: The 18-month rate at 4.45% is now BNZ’s cheapest fixed term, undercutting even the 1-year rate. That is unusual — normally shorter terms are cheaper. It suggests BNZ sees the rate-cutting cycle peaking around the 18-month mark and wants to attract borrowers to that duration.

Should I renew my mortgage for 3 or 5 years?

Pros and cons of 3-year vs 5-year fixed terms

For borrowers renewing a mortgage that is coming off a higher-rate fix, the choice between 3 and 5 years depends on two variables: how much more rates might fall and how much payment certainty you need.

The comparison below frames the decision across four dimensions.

Factor 3-year fixed (4.99%) 5-year fixed (4.99%)
Monthly payment on $500k $2,967 $2,967 (same now)
Rate risk after term ends Refix in 2028 at unknown rate Protected until 2030
Flexibility to break early Lower break fee (shorter remaining term) Higher break fee if rates fall further
Best for Borrowers who expect rates to fall more Borrowers who value certainty over savings

What this means: with identical rates on both terms, the decision is purely about how much refixing risk you are willing to carry in 2028.

Impact of BNZ’s recent rate cuts on renewal decisions

BNZ’s rapid series of cuts since April 2025 — from 4.99% on the 1-year term down to 4.49% by September — signals that the bank expects the OCR to keep falling. However, the 3-year and 5-year rates have converged at 4.99%, meaning there is no current price advantage to locking in for longer.

Borrowers with 20% equity or more qualify for BNZ’s best advertised ratesBNZ official blog. Those with lower equity may face a rate loading of 0.25% to 0.50%, which changes the math significantly.

Bottom line: With the 3-year and 5-year rates identical at 4.99%, there is no premium for choosing the shorter term today. Borrowers who think rates will be substantially lower by 2028 should pick the 3-year. Those who want to avoid any refixing risk for half a decade should pick the 5-year. The tiebreaker: your confidence in the economic outlook.

Is it better to pay off a mortgage or leave a small balance?

Financial implications of full repayment

Paying off a mortgage entirely eliminates the interest cost — which, at BNZ’s current rates, could be thousands of dollars per year on even a modest balance. For a $50,000 remaining balance at 4.49%, the annual interest cost is $2,245BNZ official blog. Paying it off saves that money outright.

Opportunity cost considerations

Leaving a small mortgage balance, however, frees up cash for other uses — whether that is investing in term deposits (currently offering around 4.5–5%), contributing to KiwiSaver, or keeping an emergency fund accessible. BNZ does not impose a penalty for full repayment on floating-rate loans, but fixed-rate loans may incur a break feeBNZ official blog.

The decision comes down to a single comparison: the mortgage interest rate versus the after-tax return on alternative uses of the cash. At current rates, the margin is narrow — paying off the mortgage is a guaranteed 4.49% return, risk-free. That beats any term deposit net of tax for a higher-rate earner.

The paradox

Paying off a small mortgage feels like financial freedom, but if you then need to borrow for a car or renovation at a personal loan rate of 12%+, you have effectively traded 4.49% debt for 12% debt. That is a net loss. Only pay off the mortgage if you have sufficient liquidity elsewhere.

Summary: your move in a falling rate market

BNZ’s aggressive rate cuts have reshaped the borrowing landscape. The 1-year rate at 4.49% is the lowest in nearly three years, and the 18-month rate at 4.45% is market-leading. The trend points lower, but no one expects a return to 3%. For the New Zealand borrower renewing a mortgage in 2025 or 2026, the choice is between riding the downward wave with a short-term fix or locking in certainty with a longer term. For a borrower with 20% equity and flexibility, the clear move is to fix for 1 or 2 years and reassess as the OCR falls further.
