New Zealand Mortgage Rates Decrease: 2026 Cuts & Forecasts

New Zealand homeowners have caught a break. After the Reserve Bank slashed the Official Cash Rate by 325 basis points across six cuts in 2025, mortgage rates have finally started trending downward—with some special offers now sitting below 5% for the first time in months. But the relief may be short-lived, with economists split on what happens next.

RBNZ OCR: 2.25% · Westpac Special Rates: Below 5% p.a. · Co-operative Bank Floating: 4.99% · 4-Year Fixed Cuts: 5.19% · 5-Year Fixed Cuts: 5.29%

Key facts at a glance

Are mortgage rates going to drop in NZ?

The short answer is nuanced: some rates have already fallen, but the window for further decreases may be closing. Westpac moved quickly after the October 2025 OCR cut, bringing all special home loan rates below 5% p.a.—a threshold that had seemed distant just months earlier. The Co-operative Bank’s floating rate of 4.99% now represents the lowest widely-available option in the market.

Recent bank cuts

Multiple lenders followed the Reserve Bank’s lead in late 2025 and early 2026. Four to five-year fixed rates dropped by approximately 20 basis points, landing in the 5.19–5.29% range. Fixed mortgage rates adjust gradually, typically within a week or so after OCR changes, while floating rates tend to shift more immediately, according to MoneyHub NZ (financial comparison platform).

Economist predictions

The consensus among bank economists points toward rate increases rather than further cuts. ANZ, Westpac, and BNZ all forecast at least one OCR increase within 2026, Opes Partners (mortgage advisory firm) reports. Westpac now expects the first OCR increase to happen in September 2026, having previously projected December. Only ASB currently predicts no OCR increase in 2026—a minority view that stands in contrast to the other major banks.

Will mortgage rates drop to 3% again?

The 3% mortgage era appears to be firmly in the rearview mirror. During the pandemic period, record-low rates briefly pushed some fixed deals into the 2% range, but that environment no longer exists. Current fixed rates in the 5.19–5.29% range for 4–5 year terms reflect a fundamentally different monetary policy landscape.

Historical lows

The OCR was introduced in March 1999 and has never been lower relative to neutral estimates than it is today. The RBNZ has cut the OCR by 325 basis points from August 2024 to November 2025, bringing it from 5.50% to 2.25%. Yet even at this level, economists do not anticipate a return to pandemic-era lows. The neutral OCR estimate of 3% represents the theoretical rate that neither stimulates nor restrains the economy—and markets are pricing in movement back toward that level.

Current trajectory

ANZ, the only major bank publishing specific mortgage interest rate predictions, expects the 1-year mortgage rate will reach 5.2% by December 2026 and 5.5% by September 2027, Opes Partners notes. Opes Partners itself predicts the 1-year rate will hit 5% by March 2027 and 5.25% by March 2028. Westpac expects mortgage rates to rise from the mid-4% range to the 5.5% to 6% range. The trajectory points upward, not toward the 3% territory of years past.

Should I fix my mortgage for 2 or 5 years in 2026?

This decision hinges on whether you believe the rate cuts are over and increases are imminent. The data suggests the latter: with most economists forecasting OCR rises within the next 12–18 months, locking in today’s rates could be advantageous. However, there is a counterargument worth considering.

2-year vs 5-year rates

The 4–5 year fixed rates have seen the most significant recent cuts, dropping by around 20 basis points in February 2026. This makes longer-term fixing more attractive from a rate perspective than it has been in some time. A borrower locking in at 5.19% for four years would avoid the anticipated rate increases that 1–2 year terms would expose them to when those terms expire.

Pros and cons

The RBNZ has signalled its intention to hold OCR fairly steady in 2026 before beginning a transition back toward the neutral rate toward the back end of the year, Squirrel (mortgage broker) reports. That signals patience may be rewarded—but patience carries its own risks.

Is 4.5% a good mortgage rate?

Compared to the rates available in 2023 and early 2024, 4.5% would represent an excellent deal. Compared to the 2–3% rates of the pandemic years, it would represent a significant increase. The answer depends entirely on your reference point.

Compared to current offers

Westpac’s special rates below 5% p.a. post-October 2025 have brought the market to a point where sub-5% fixed rates are achievable for well-qualified borrowers. The Co-operative Bank’s floating rate of 4.99% sits tantalizingly close to the 4.5% threshold, but that rate carries the risk of immediate increases if the OCR moves upward.

Historical context

The RBNZ meets seven times per year to review the OCR, according to MoneyHub NZ (financial comparison platform). With most meetings now expected to result in unchanged decisions before increases begin, the current environment represents a transitional moment—neither the high-rate period of 2023–2024 nor the ultra-low era of 2020–2021.

Will NZ house prices go up in 2026?

The connection between mortgage rates and house prices is well-established: lower rates reduce the cost of borrowing, making purchases more affordable and stimulating demand. The significant OCR cuts of 2025 have set the stage for potential price appreciation, though the extent remains uncertain.

Rate impact on housing

With the OCR at 2.25%—well below the neutral estimate of 3%—the Reserve Bank has placed the economy in stimulatory territory. Lower OCR usually results in banks reducing floating mortgage rates quickly, MoneyHub NZ notes. This has already translated into lower fixed rates and improved affordability for new borrowers.

Confidence indicators

Market confidence in the housing sector has improved alongside the rate cuts. The combination of lower rates and the expectation that OCR increases will be gradual has given buyers and sellers more certainty about the near-term outlook. However, the anticipated rate rises in 2026 and 2027 could cool enthusiasm before significant price growth materialises.

Major bank forecasts compared

Six banks, six different views on what comes next. The table below shows where each major lender stands on the OCR outlook for 2026.

The divergence is notable: ASB stands alone in predicting no OCR increase in 2026, while the other major banks and the RBNZ itself anticipate upward movement. This disagreement underscores the genuine uncertainty facing borrowers trying to choose a fixing strategy.

Rate cut timeline

The journey from peak rates to today’s levels spans 18 months and involved the most aggressive cutting cycle in recent memory.

The RBNZ cut rates six times in 2025, reducing the OCR by 2 percentage points in total. That aggressive easing cycle has now paused, with the central bank signalling a shift toward gradual normalisation rather than further stimulus.

What’s confirmed and what’s still unclear

High confidence exists around the rate cuts already delivered; less certainty surrounds the path forward.

What economists are saying

Rate cuts are over. Mortgage rates will rise as soon as September.

Fixed mortgage rates adjust more gradually within a week or so after OCR changes, while lower OCR usually results in banks reducing floating mortgage rates quickly.
