Why Now Could Be the Time to Reconsider Fixing Your Mortgage Rate

Why Now Could Be the Time to Reconsider Fixing Your Mortgage Rate

With the Reserve Bank holding the Official Cash Rate (OCR) steady and mortgage rates beginning to ease, many New Zealand borrowers are asking the same question: Is now the time to fix, and if so, for how long?

Recent data suggests that the decision window could be shorter than expected. According to leading market analysts, homeowners likely have months, not quarters, to take advantage of the lowest rates before the next cycle begins.

Where Are We in the Mortgage Cycle?

Wholesale interest rates — which influence what banks pay to fund mortgages — indicate that fixed rates are nearing their floor. While modest rate reductions are possible through the first half of 2026, any downward movement is expected to be limited.

Inflation remains sticky, and while the economy is showing signs of stability, global pressures and funding costs could start to push rates upward again later in the year. In short, New Zealand may be reaching the bottom of the interest rate curve.

For borrowers, this means it could be time to reassess mortgage structure and term strategy. Waiting too long in hopes of deeper cuts could mean missing the best available rates.

Two- and Three-Year Fixes in Focus

While one-year terms have dominated since mid-2023, the value gap between short and medium-term fixed rates has narrowed.

  • Two-year terms are currently the “sweet spot” for many borrowers, offering stability while leaving flexibility for future rate changes.
  • Three-year terms can lock in certainty for households who prioritise budgeting confidence over chasing marginal rate drops.

For investors or homeowners managing larger loans, a split mortgage structure, combining different fixed terms or blending fixed and floating, can help balance risk and flexibility.

Short-Term vs Long-Term Thinking

Fixing your mortgage isn’t about timing the market perfectly; it’s about managing risk and creating stability.

Borrowers who fix for too short a period risk rolling over into a higher rate if the market rebounds sooner than expected. Those who fix for too long may miss potential savings if rates dip slightly lower in the next few months.

Ultimately, it’s about your individual situation: your goals, cash flow, and comfort with change.

Eureka’s advisers often recommend a layered strategy: splitting loans across different terms to reduce exposure to rate shocks while maintaining some flexibility to take advantage of future decreases.

What Borrowers Should Be Doing Right Now

  1. Review Your Mortgage Terms – Don’t wait for your bank to contact you. Get ahead by understanding when your fixed term expires and what options are available.
  2. Compare Across Lenders – Banks vary significantly in rate competitiveness and lending criteria. An independent adviser can access a wider range of options.
  3. Plan for Repayment Resilience – Build in buffers for household budgets, particularly if you’ve enjoyed lower fixed rates that are soon to expire.
  4. Consider Future Flexibility – A slightly higher rate with more prepayment or lump-sum options may suit you better long term.

What to Expect in the Year Ahead

Economists expect moderate rate stability through the first half of 2026, followed by the potential for upward movement if inflationary pressures return. Borrowers who secure mid-term fixes now could insulate themselves from volatility later in the year.

Eureka’s recent client reviews reveal that more homeowners are opting to lock in part of their loan now while keeping a portion floating or short-term fixed, allowing them to benefit from future cuts while maintaining repayment certainty.

Final Thoughts: Take a Proactive Approach

The current rate environment presents an opportunity, but not an indefinite one. With the market potentially shifting within months, acting early can mean the difference between financial stability and uncertainty.
