If you’re holding off on fixing your home loan or weighing up your next move — you might want to take note. The major Kiwi bank Westpac has just reduced several of its fixed-term home loan offers, signalling a potentially important shift for homeowners, borrowers and the wider housing market.

What’s changed

As of 24 October 2025:

• The 18-month and two-year special fixed rates have dropped to 4.45% p.a.
• The three-year fixed rate is now 4.75% p.a.
• The six-month fixed rate has been cut to 4.89% p.a.
  These changes give Westpac the lowest two- and three-year fixed-term rates among New Zealand’s five largest banks at that time.

Sarah Hearn, Westpac NZ’s Managing Director of Product, Sustainability & Marketing, says this is “the third time this month we’ve cut our two-year advertised special home loan rate,” and over the past year they’ve reduced it by a total of 1.2%.

What’s driving the move

Two big forces are at play:

1. Policy easing – The Reserve Bank of New Zealand (RBNZ) cut the Official Cash Rate (OCR) by 50 basis points to 2.5%. Lower funding costs give banks more margin to offer competitive rates.
2. Competitive pressure – Other banks (like BNZ and ASB Bank) have trimmed fixed-term rates too, so Westpac is responding to maintain appeal.

What this means for you

• If you’re considering fixing your rate, now could be a good time. The drop in two- and three-year offers gives you better certainty and still attractive rates.
• If you’re on a floating rate, this signals increased competition and potential downward pressure on fixed rates, which might make locking in for a longer term more appealing.
• If you’re a broker, lender or a borrower with upcoming renewals, this provides an opportunity to revisit loan structure, split terms and future cash flow modelling.

Things to keep in mind

• Even with the rate drop, always test your budget against higher future rates. The “stress test” scenario remains important (for example, what if fixed rates rise again?).
• Consider the term you fix for. Westpac is noting an increasing number of borrowers are shifting from one-year fixes to 18-month or two-year terms for more stability.
• The reduction in rates doesn’t always mean dramatically lower repayments if you’re close to the end of a term or have a high-LVR mortgage; always run the numbers.
• Given the shifting housing market and broader economic environment, remember that rate decisions are just one piece of the puzzle.

Why this matters for the broader housing market

This rate-cut move by a major bank is more than just good news for individual borrowers — it hints at broader market sentiment. Lower fixed rates can stimulate buyer confidence, potentially increase borrowing, and support housing activity when inventory and demand may be lagging.

The takeaway

Westpac’s recent rate cuts are a welcome change for many borrowers. Whether you’re looking to fix, split your loan, or simply reassess your strategy, now is a solid moment to review your home-loan position. After all, when banks start offering more favourable terms, wise Kiwis take notice.
