When your fixed-rate home loan is about to expire, it’s tempting to chase the lowest rate you can find. But the cheapest rate isn’t always the smartest choice. At Best Mortgages, I help Tauranga homeowners compare refix options against their budget and plans.
Before locking in another fixed term, think about what’s ahead:
If you fix for too long and then need to sell or restructure, you could face a break cost, which can be expensive if rates have fallen. Choose a term that fits your likely timeline.
A planning check: For a homeowner in Papamoa considering a move, the fixed period should be checked against the likely sale date. Ask what early-repayment costs could apply, and compare repayment certainty with the flexibility you may need. Do not choose the term on rate alone.
Ask yourself: do you value stability or flexibility right now? If predictable repayments help you sleep better, a longer fixed term can bring certainty. If you expect income or lifestyle changes, a shorter term may suit you better. The “best” rate is the one that suits your goals — not just the lowest number.
You don’t need to refix the whole mortgage on one term. Splitting into two or three parts — each with a different term — can smooth out rate changes and reduce pressure when one portion rolls over.
Example: one-third fixed for 1 year, one-third for 2 years, one-third for 3 years. This structure means only part of your lending refixes each year. If rates rise, you won’t feel the full impact at once. If rates fall, it takes longer to benefit — it’s a trade-off. Comparing repayments under both scenarios can help you decide.
Many people only start thinking about refixing a few weeks before expiry. That can limit your choices. As a planning guide, review your options six to eight weeks before expiry. The dates when you can lock a new rate, any fee and the available terms depend on your lender; checking early does not mean every lender will hold a rate for that whole period.
As a mortgage broker in Tauranga, I can help you compare the available terms and loan structures. Term lengths, timing, repayment settings and split structures all affect the decision. It’s worth checking those details before committing to a new fixed period.
The structure often matters more than the headline number. Ask:
For a hypothetical household in Bethlehem comparing a one-year/two-year split, model higher and lower rates when the first portion expires. Only part of the loan changes rate then. Compare the repayments and flexibility you could manage under either outcome; the split does not guarantee savings.
A clear plan gives you time to compare your choices and understand the repayments before the new fixed period starts.
If your fixed term is coming to an end, bring your expiry date, current balance and any expected changes to your budget or plans.

Start reviewing options 6–8 weeks before your fixed term ends as a planning guide. Check your lender’s actual rate-lock dates, conditions and any fee before choosing a new fixed period. If your circumstances may change soon — job move, renovations, new purchase — consider a shorter term for flexibility. If you value predictable repayments, a longer term can provide certainty. You can talk through those dates and plans with me before making a choice.
Fixed rates give certainty for a set term; great for stable budgeting. Variable (floating) rates move with the market and generally give more flexibility for extra repayments; confirm the lender’s terms and fees. One option is a split: part fixed for stability, part floating for flexibility. Compare not only the rate, but also fees, break-cost risk, and how each option fits your next 12–24 months.
A straightforward refix with your current lender differs from refinancing to another lender. Ask about any variation or rate-lock fee for the refix, and obtain an early-repayment quote if changing before the existing fixed period ends. Switching lenders can also involve legal, valuation, discharge and cashback-repayment costs. Compare those separately using my refinancing comparison guide.
A longer fixed-rate period does not necessarily mean savings and is different from extending the overall repayment term. Compare repayments under the available rates, early-change costs and clearly labelled higher- and lower-rate scenarios. Future rates are unknown, so lifetime-interest estimates depend on the assumptions used. Ask for side-by-side scenarios (current structure vs longer fixed term vs split) using your balance and remaining years. The best choice is the one with the most comfortable cash-flow and acceptable flexibility for your plans.
