If your fixed-rate home loan is coming up for renewal, check the expiry date, your lender’s notice and the choices available for the next period. I’ve set out the steps below so you can check the dates, repayments and instructions before your current rate ends. My work as a mortgage broker in Tauranga includes ongoing support with refixing as your plans change.
Your agreed fixed rate applies for a set period. At its end, the next rate and repayments depend on your lender’s terms and the option you choose. Check what happens if you give no instruction, and update your budget using the actual offers available to you.
Lenders have different notification and refix windows. Check your expiry date and ask when you can choose a new rate, whether a rate-lock fee applies, and the deadline for instructions. Depending on your loan and lender, the options may include:
Your loan may move to a variable rate if you give no instruction, but the default rate and any margin depend on your agreement. Compare the actual cost and flexibility with the available fixed choices before deciding.
There’s no one-size-fits-all answer. A fixed loan offers certainty, while a variable loan gives flexibility.
Ask yourself:
A shorter fixed period means an earlier rate decision; a longer one gives rate certainty for longer. Choose around your budget and expected plans rather than a forecast that rates will settle or fall.
To continue fixing, choose a new fixed-rate period on the lender’s available terms. A straightforward same-lender refix may use the existing loan agreement and need less administration than a new loan application. Confirm the new rate, repayments, dates and any conditions before accepting.
That’s both the advantage and drawback of fixed lending:
Ask whether your lender allows a rate to be locked before the current fixed period expires, when that option opens and whether there is a fee. The available terms vary; a rate lock does not establish what future rates will do.
Yes, but tread carefully. Breaking a fixed contract can trigger break fees or re-pricing costs, especially if market rates have dropped since you fixed. Ask the lender for a dated early-repayment quote and its terms before making a change. Compare that cost, any other fees and the proposed repayments; a top-up, partial break or refinance does not automatically remove it.
Before the expiry date, confirm in writing the balance being refixed, the agreed rate, the new period and repayment amount, and when the instructions take effect. If leaving some lending floating, understand its rate and the cost of that flexibility. Keep a copy of the confirmation and check the first payment against it.
Before your fixed period ends, check the lender’s deadline and default terms, then choose the option that fits your budget and plans. Starting around two months ahead is a useful planning prompt, but actual refix and rate-lock windows vary. Floating can be a deliberate choice when its flexibility is worth the cost.

It’s best to get in touch 8–10 weeks before your fixed rate expires. Treat this as planning time, then check your lender’s actual decision and rate-lock dates. Compare the default rate with your choices and leave extra time if a lender switch or new borrowing needs assessment.
Re-fixing offers certainty for the agreed fixed period, subject to the loan terms. A variable rate gives flexibility to make extra repayments or switch lenders more easily. A split loan combines the two, with trade-offs to consider. I can help you compare the repayments and flexibility of the available options.
Break costs depend on the loan balance, remaining term, and current wholesale rates. If market rates have fallen since you fixed, the bank may charge a fee to recover the difference. Each lender’s formula is slightly different, so always ask for a quote before breaking your term. I can help you compare that quote with the potential benefit of a change.
A straightforward same-lender refix may not need a full new application. Changed borrowing or a new lender can require further assessment. Ask which documents apply; these may include:
Proof of income (recent payslips or financials if self-employed)
Updated ID and proof of address
Current loan statements
Lender-specific application or variation documents
A new lender may also request property evidence, such as a copy of your title and rates notice. Ask for the checklist that applies to your transaction rather than assuming every refix needs the same evidence.
