Quick answer
A mortgage break fee only applies if you end or reduce a fixed-rate home loan before its term is up, and it is meant to recover the bank's cost, not profit. Topping up or refinancing your first mortgage can trigger one. A second mortgage sits behind it, so the fixed loan stays untouched and no break fee arises.
Key points
- A break fee is triggered by changing a fixed loan, not by borrowing against the house.
- Banks base the fee on the gap between wholesale rates then and now, so it can be large, small or nil.
- Ask the bank for a written break-fee figure for the exact day, because it moves daily.
- A second mortgage leaves the fixed first mortgage alone, so there is no break fee to price.
If your home loan is fixed and you want to use the equity for the business, the break fee is the cost to price before anything else. It only arises if you end or restructure the fixed loan early. Borrowing against the property in a way that leaves the fixed loan alone avoids it altogether, which is the main reason owners use a second mortgage.
When does a mortgage break fee actually apply?
A break fee is charged when a fixed-rate loan is repaid, or reduced, before the fixed term ends. It is not charged for borrowing more against the house in general. That distinction is the whole game for a business owner, because three common ways of releasing equity treat the fixed loan very differently.
| Route | What happens to the fixed loan | Break fee? |
|---|---|---|
| Top-up with your current bank | Often stays as is, with the new money added as a separate portion | Often none, but check |
| Restructure or refinance the whole first mortgage | The fixed portion is repaid early | Possible |
| Second mortgage behind the first | Untouched | None on the fixed loan |
The top-up row is where owners get caught out. Some banks add new money as its own portion. Others rewrite the whole loan, and the fixed part is treated as repaid. The only reliable answer is the bank’s written one.
How is the break fee worked out?
New Zealand law limits lenders to recovering their costs rather than profiting from an early repayment, as Interest.co.nz notes. The cost is the bank’s loss on the funding it arranged for your fixed term.
Banks using the wholesale method compare the wholesale swap rate at the start of your fixed term with the swap rate today, for the remaining time. When the Commerce Commission reviewed break fees, it distinguished this wholesale method from a retail-rate method used by some other banks. Banks don’t publish every input, so any online estimate, including the one on Interest.co.nz, is an estimate only.
In rough terms:
fee ≈ loan balance × fall in wholesale rates since you fixed × years remaining
Here is a worked example, clearly illustrative. A Hamilton building firm’s owners have a $500,000 fixed loan with 18 months to run. If wholesale rates have fallen by half a percentage point since they fixed, the rough fee is $500,000 × 0.5% × 1.5 years, so about $3,750. Had wholesale rates instead risen, the bank hasn’t lost anything, and the fee could be small or nil. Same loan, same time left, very different outcome.
Why the timing matters more than the loan size
Three things move the number:
- Direction of wholesale rates since you fixed. Fixed when rates were high and they’ve since dropped: expect a fee. Fixed when they were low and they’ve since risen: the fee can shrink to almost nothing.
- Time left. The fee is spread over the remaining term, so breaking with two months to go costs far less than breaking with two years to go.
- How much of the loan you touch. Repaying part of a fixed loan can trigger a proportionate fee. Leaving it alone triggers none.
I haven’t quoted where swap rates sit today, because that moves daily and what matters is the gap against your own fixing date. Ask your bank for the figure on the day, in writing, and check it against the Canstar explainer or a calculator for a sanity check.
Can you get the break fee waived?
Banks aren’t obliged to waive it. If you think a fee has been miscalculated, or you were misled about it, you can complain to the bank and then to the Banking Ombudsman Scheme. In practice, the more dependable ways to cut a break fee are timing and structure:
- Wait until the fixed term ends or is close to ending, then restructure for free or nearly free.
- Break only if the quoted fee is small, or nil because rates have risen.
- Avoid breaking altogether by borrowing behind the first mortgage.
What does a second mortgage do instead?
A second mortgage is secured against the same property but ranks behind your bank. The bank’s fixed loan keeps running exactly as written, so there’s no early repayment and no break fee. You borrow against the equity between what the property is worth and what you owe, within the lender’s maximum combined loan-to-value limit.
Business lending of this kind runs from $20,000 to $5,000,000. Same-day funding can be possible for $20,000 to $250,000, and larger amounts can be possible within 24 to 48 hours. See second mortgage business loans for how it works, and our guide to second mortgage versus refinancing your first mortgage for the broader comparison.
If you’d like a straight read on whether leaving your fixed loan alone makes sense for your numbers, you can start a 60-second enquiry.
When is breaking the fixed loan the better move?
A second mortgage isn’t always the cheaper path. A bank top-up or refinance is generally cheaper over a long period, so it can win when:
- the break fee is small or nil, and
- the bank will actually lend for a business purpose and can move at the speed you need, and
- you need the money for a long period rather than a bridge.
Banks often take weeks, may want full business financials, and can decline business purposes. If your gap is a GST bill, a supplier deposit or a contract that starts next week, the weeks matter as much as the break fee. A bank will often win on cost, the second mortgage on speed, and you’re deciding which of the two your situation rewards.
A simple way to compare the two routes
Put these numbers side by side:
- Break fee quoted in writing for the day you’d proceed.
- Bank’s timeline and fees to restructure, including legal and valuation costs.
- Second mortgage costs: establishment, legal and the cost of the money for the months you’d hold it.
- How long you’ll need the money. Under about a year points towards a second mortgage; several years points towards restructuring.
- How sure the repayment is. A clear exit, such as a debtor, a sale or a refinance in a few months, suits a short second mortgage.
Add up the total dollars you’d repay under each route. Compare dollars, not headline numbers, because a cheaper-looking structure can still cost more once a break fee and the bank’s delays are counted.
What about the fixed loan terms behind the scenes?
Two checks before you commit either way. First, read your first mortgage terms for any clause about further security over the property. If consent from the bank is needed for a second mortgage, your solicitor can usually deal with it in parallel. Second, ask what happens to your fixed loan if the second mortgage lender registers behind it: nothing should change, but your bank may want to be told.
If a caveat-style loan is more suitable for a very short timeframe, caveat loans work on a similar principle of leaving the fixed first loan alone.
An illustrative decision
An illustrative Tauranga hospitality owner has a fixed home loan with 14 months left and wants $150,000 to fit out a second venue before summer. The bank’s quote to restructure includes a break fee in the low thousands and a four-week timeline. The owner’s fit-out contractor needs a deposit in ten days. A second mortgage leaves the fixed loan alone and can be possible in days. The owner holds it for six months until the venue is trading, then refinances the lot into the bank once the fixed term ends. The break fee is avoided altogether, and the cost of the short-term money is the price of speed.
Check where you stand
Releasing equity for the business shouldn’t involve a nasty surprise from a loan you thought you’d left alone. Whether your best route is to wait out the fixed term, restructure with the bank, or borrow behind it, the first step is knowing your numbers.

Frequently asked questions
Do I pay a break fee if I top up my home loan for the business?
Not necessarily. Many banks add a top-up as a new loan portion and leave the existing fixed portion running, so nothing is broken. But if the bank restructures the whole loan, or you refinance to another lender, the fixed portion can be broken and a fee can apply. Ask which of those the bank is proposing before you sign.
How is a mortgage break fee calculated in NZ?
Banks that use the wholesale method compare the wholesale swap rate when you fixed with the swap rate on the day you break, then apply that gap to the balance and the time left on the term. Some banks work from retail rates instead. Because banks don't publish full formulas, ask for the figure in writing for the day you intend to break.
Can the break fee be zero?
Yes. Break fees recover a loss. If wholesale rates have risen since you fixed, the bank has not lost on your loan and the fee can be small or nothing. If rates have fallen, the fee can be large. It depends on timing, so it is worth checking rather than assuming.
Can a bank waive a break fee?
A bank can choose to, but it isn't obliged to. The practical way to reduce a fee is to wait until the fixed term ends, break close to maturity when little time remains, or avoid touching the fixed loan at all.
Does my bank have to agree to a second mortgage?
Usually your first mortgage terms say whether further security over the property needs the first lender's consent. Your solicitor checks this early. Where consent is needed, it's a matter of timing rather than a fee on the fixed loan.
Is a second mortgage always cheaper than breaking my fixed loan?
No. A second mortgage generally costs more over time than a bank top-up, so it makes most sense for a shorter period with a clear way to repay. If your break fee is small or nil and the bank will lend for business purposes, restructuring can win. Compare the total dollars repayable under each route.
