Mortgage refix or refinance? Your options when your fixed rate ends

Your fixed mortgage rate has an end date, and there's a decent chance it lands between now and next winter — 68% of New Zealand's fixed-rate home loans are due to reprice in the 12 months from early 2026. A few weeks out, your bank will email you. The email offers a refix: pick a new term from a short list, tap a button, done inside a minute. What the email doesn't say is that the end of a fixed term is the one moment in the life of your mortgage when you can change almost anything about it at almost no cost — lender, structure, term, repayments. All of it is on the table, briefly.

In this episode, SortMe Resident Money Writer Hugo Jonston unpacks the refix-vs-refinance-vs-restructure decision most Kiwis one-tap through without realising a three-option choice is being framed as a one-option formality. The past two years were kind to anyone rolling off a fix — the average rate being paid across all NZ mortgages fell from a 6.39% peak in October 2024 to 5.17% by late 2025 — but that tailwind is nearly spent, the OCR sits at 2.25%, and most bank economists have the next moves pencilled up. SortMe Founder & CEO Carl Thompson: "The households that refix well aren't the ones who can recite the OCR track. They're the ones who turn up knowing their own numbers: every tranche, the equity position, what the household really spends. When that's already on one screen, you spend your energy negotiating instead of assembling."

In this episode:

• The one-tap trap — why 68% of NZ fixed loans repricing this year is the largest window of leverage most households will get on their biggest debt, and why the bank's email is deliberately framed as a formality
• Refix vs refinance vs restructure — what each word actually means, when a refinance triggers a full application (income evidence, credit check, valuation, lawyer), and why cash contributions almost always carry clawback terms
• Why the boring answer (a simple refix) is sometimes correct — a genuinely competitive offer, a recent refinance with an active clawback, sub-20% equity locking you out of the sharpest specials, or an income change that would make a fresh application hard
• When refinancing deserves the paperwork — a market-versus-carded-rate gap that the bank won't move on, a cash contribution that offsets legal and valuation costs several times over, or a product (offset, specific structure) your bank won't do
• Why the boundary between refix and mid-term matters — everything above applies at the end of your fixed term; break your fix mid-term and the break fee usually wipes the gains
• The rate-card signal for 2026 — sharpest one-year around 4.65% versus sharpest two-year around 5.19%, and what banks charging more for longer money is telling you about their view of the next OCR moves
• Six months out: find the end date of every tranche (Auckland households often have two, three or four), confirm your equity, check your last six months of household income, and note the exact rate gap you're paying vs the market
• Three months out: get three written offers (a broker can pull them without you redoing the paperwork three times), sense-check the fixed-floating split, offset/revolving-credit fit, and whether four tranches should become two
• One month out: confirm term and rate-lock length, choose fortnightly over monthly, and — if the new rate is lower — resist the automatic lower repayment so the difference quietly shortens your loan
• What SortMe pre-loads for the conversation — every tranche's balance/rate/end date, net worth including the house so the equity question answers itself, six months of income and spending as the evidence a refinance application asks for, and Safe to Spend showing what the new repayment does to your week

Mortgage refix or refinance. Your options when your fixed rate ends. Article by Hugo Johnston, Resident Money Writer. Your fixed mortgage rate has an end date, and there's a decent chance it lands between now and next winter. You'll have company. 68% of New Zealand's fixed rate home loans are due to reprice in the 12 months from early 2026. A few weeks out, your bank will email you. The email offers a refix. Pick a new term from a short list, tap a button, done inside a minute. What the email doesn't say is that the end of a fixed term is the one moment in the life of your mortgage when you can change almost anything about it at almost no cost. Your lender, your structure, your term, your repayments, all of it is on the table, briefly. So before you tap the button, it's worth being clear on what your options actually are. Refix, refinance, restructure, what the words mean. A refix means staying with your current lender and locking in a new fixed rate when the old one ends. No new application, no lawyer, no fees. It's the path of least resistance, which is exactly why banks make it a one-tap job. Convenience is the appeal, but you might be missing out on a better deal. A refinance means moving the whole mortgage to a different lender. That's a genuine application. Income evidence, a credit check, sometimes a registered valuation, and a lawyer to shift the security from one bank to another. In return, you get something your own bank rarely volunteers, a lender that has to win your business. That can mean a sharper rate and often a cash contribution toward your costs. Cash contributions come with clawback terms, typically requiring you to stay a set number of years or repay some of the cash, so read those terms before you count the money. A restructure sits between the two, staying put but changing the shape of the loan. The fixed floating split, the number of tranches, an offset or revolving credit facility, the loan term itself. At refixed time, these changes cost little or nothing. Midterm, they can cost plenty. Here's the answer to the question most people are really asking. No, you don't have to refix. Rolling off a fixed term triggers no penalty and no obligation. The bank's one-tap email frames a three-option decision as a one-option formality, and the framing works because most people take it. When a simple refix is the right call. Sometimes the boring answer is correct. A refix makes sense when your bank's offer is genuinely competitive once you've checked it against the market, not just against their own carded rate. It makes sense if you refinanced recently, and a cash contribution clawback would eat any gains from moving again. It makes sense if your equity sits below 20% because the advertised special rates generally require at least 20% equity and your bargaining position across the market is weaker. And it makes sense if your income or circumstances have changed in ways that would make a fresh application hard, since a refix with your existing lender usually doesn't require one. When refinancing deserves a serious look. Switching earns its paperwork when the numbers say so. If your bank's offer clearly sits above the market's sharpest rates and doesn't move when you push, the gap applied to your balance is what staying loyal costs you every year. On a $700,000 Auckland mortgage, even a small gap runs to thousands. A cash contribution from the new lender can offset the legal and valuation costs of moving, sometimes several times over. And sometimes the reason is product, not price, an offset account your bank doesn't offer, or a structure they won't do. One boundary matters here. Everything above applies at the end of your fixed term. Moving lenders midterm means breaking your fix, and break fees can wipe out the gains. We've covered what an NZ mortgage break fee really costs. Run those numbers before you touch anything before its end date. Why this decision matters more this year. The past two years were kind to anyone rolling off a fix. The average rate being paid across all NZ mortgages fell from a 6.39% peak in October 2024 to 5.17% by late 2025, as wave after wave of borrowers rolled onto cheaper money. That tailwind is nearly spent. The OCR sits at 2.25%, and most bank economists expect the next moves to be up, with hikes penciled in for the second half of 2026 and into 2027. The rate card already tells the story. In late June, the sharpest one-year rate sat around 4.65%, while the sharpest two-year was 5.19%. When banks charge more for longer money, their pricing rate rises in. So whichever path you take, the term you choose carries real consequences. Fix short and you're back repricing just as any hikes land. Fix long and you're paying over half a percent for the certainty. There's no universally right answer, only the right answer for your household's numbers. Which is why the preparation below matters more than the label on the decision. Six months out, get the full picture. 20 minutes once. That's the time investment, and it's worth it whether you end up refixing, refinancing, or restructuring. Find the exact end date of every tranche. Plenty of Auckland households are carrying two, three, or four loan tranches, split over the years by top-ups and past refixes, each with its own rate and end date. Write them all down. Balance, rate, end date. A tranche you forgot about is a decision made by default. Confirm your equity. This is the gate on your options. If your property's value has moved since you last checked, your loan-to-value ratio has moved too, possibly across the 20% threshold in either direction, four. Above it, the whole market is open to you. Below it, a refix with your current lender, maybe the realistic path, and you want to know that before you spend energy shopping. Check your household's income trend. Not what you earned in 2024 when you last fixed. What has landed in the accounts over the past six months after tax. A refinance application will ask for exactly this, so knowing it early tells you whether switching is practical. It also shapes the refix. If income has risen, you may want to shorten the loan term rather than pocket a lower repayment. Note the gap. What rate are you paying now and what's on the rate card today? That gap applied to your balance is roughly what's at stake each year. It's also your first read on whether a refinance is worth the paperwork. It focuses the mind wonderfully. Three months out, make the banks compete. Get three written offers. Your own bank's in-app offer is a starting position, not a market price. This is the step where refix or refinance stops being theoretical. With competing offers in hand, you either use them to pull your own bank down and refix on better terms, or you take the best one and switch. A mortgage broker can pull competing offers without you redoing the paperwork three times, and choosing one is its own decision we've covered separately. If you'd rather run it yourself, two phone calls do the same job. Either way, written offers with any cash contribution and its clawback terms spelled out. Sense check your structure, the fixed floating split, whether an offset or revolving credit facility fits how your money moves, whether four tranches should become two. Refix time is when structure changes are close to free, whichever lender you land with. One month out, lock the details. Confirm the term and ask how long the offered rate is held for. A rate lock matters more when rates are drifting up and matters doubly if a refinance settlement date could slip. Confirm payment frequency, since Fortnightly quietly beats monthly over a full term. If the new rate comes in below your old one, resist the automatic lower repayment. Keep paying the old amount and the difference shortens your loan without you feeling it. Decide any top-up, offset, or restructure now while the account is open on someone's screen. Once you fix, that door mostly closes for the term. Please note that your personal situation may differ, and the information above is general. If you have questions relating to your financial situation, please consult a licensed financial advisor. What sort me preloads for the conversation? Most of the checklist above is assembly work, pulling numbers out of banking apps, property estimates, and pay slips. Sort me holds them already. Connect your accounts, and every mortgage tranche appears in a single view with its balance, rate, and end date. Your net worth, house included, so the equity question, the one that decides whether refinancing is even on the table, answers itself. The cash flow view shows your household's income and spending trend across the past six months, which is the exact evidence a refinance application or broker asks for. Once an offer is on the table, safe to spend shows what the new repayment does to your week-to-week position before you commit to it. Carl Thompson, CEO of SortMe, puts it this way: The households that refix well aren't the ones who can recite the OCR track. They're the ones who turn up knowing their own numbers, every tranche, the equity position, what the household really spends. When that's already on one screen, you spend your energy negotiating instead of assembling. The conversation you're preparing for. A good roll-off conversation sounds different when the prep is done. You're not asking what's the rate. You're saying two tranches roll in November, we're at 65% LVR, income is steady, here's what we pay now, and here's the written offer your competitor made us. That household gets sharper offers whether it stays or switches because it's visibly ready to walk. 20 minutes now, thousands later, for the life of the loan. If you'd rather not spend a weekend assembling the file, sort me puts your tranches, equity, and cash flow on one screen tonight. Start a seven-day trial for one dollars and walk into your refix or your refinance prepared. Still have questions? Ask someone licensed to answer them. A guide like this can take you a long way, but it stops where your specifics begin. Whether one year beats two, whether a cash contribution outweighs a clawback, whether four tranches should become two. Those calls depend on your household's numbers, your plans, and your appetite for risk. Everyone's situation is different, and a licensed financial advisor can look at the whole picture and give you advice that's actually about you, which no article can. If you're a sortme user, you don't have to go hunting for one either. We'll match you with a financial advisor best suited to your situation. And because your tranches, equity, and cash flow already live in SortMe, you'll walk into that first conversation with the file ready. This article is general information, not personalized financial advice. The right fix, term, and structure depend on your own situation.
