Why refixing deserves more than five minutes

Banks love it when clients refix their mortgages online; but it's not always the best option for borrowers.

Tuesday, November 18th 2025

Banks love it when clients refix their mortgages online. It's quick, it's efficient and it saves them money.

But the vast majority of people want to have a proper conversation before they make their refix decision, not after they've already locked themselves in, Campbell Hastie, chief at Hastie Mortgages says.

He says he is seeing more and more people wanting to have these conversations with an adviser before they make their refix decisions.

“Too many people are making these decisions in isolation, often just clicking whatever option their existing bank suggests, without considering whether it suits their situation.”

Hastie had a recent client who had been doing this for the past decade. Whilst it hadn't been a disaster, it hadn't been optimal.

The problem became obvious when his 3.4% rate was due to roll off onto about 5%, he says. That's still a reasonable rate historically, but when applied to a $750,000 mortgage, that jump represents a significant increase in monthly payments.

“If he'd split his mortgage years ago, he could have spread this impact out – maybe taking some of the pain last year and some next year, rather than copping it all at once.

“Because he'd been doing everything himself through his banking app, he'd never considered splitting as an option.”

“A bank's online system doesn't exactly walk clients through strategic mortgage planning – it just lets them pick a rate and term. Job done, from its perspective,” Hastie says.

What you can't do online

Most people don't realise that online refixing only covers the basics. “They can set their rate and choose a term, and that's about it.

“They can’t restructure their loans, adjust split arrangements, add revolving credit or switch from principal and interest to interest only for a while."

Hastie says he regularly has conversations with people who are anticipating changes in their lives –planning renovations, considering a career change, or thinking about investment property.

“These situations often call for tweaking the mortgage structure, not just picking a new rate.”

The other limitation is more fundamental: companies and trusts can't refix online at all. Those with a mortgage held in a business structure, are going to need to talk to someone regardless.

The real cost of going it alone

What drives this point home for Hastie is the conversations he has with new clients whose mortgage arrangements are completely out of whack with their circumstances.

“Usually, it's because they haven't talked to anyone about their mortgage for years – they've just been clicking their way through each refix without any strategic thinking.

“I'm not saying people can't refix online – plenty of people know exactly what they want to do and are confident in their decision. For them, the DIY approach works fine.”

But for many, he says a refix decision might look deceptively simple on the surface, but how they got to that decision – and whether it actually suits their situation – is often more complex than it appears.

If circumstances have changed since the last refix, then that's where a proper conversation with an adviser pays dividends.

Yes we have ASB to thank for taking away the adviser's ability to manage the re fix process for their clients, this was an important part of the adviser /customer relationship that banks think will save them money by taking this away from advisers and forcing customers to lock in a rate direct online, banks forgot to measure if customers stay with the same bank longer when the adviser managed the re fix process, which I would expect they did , now banks are complaining that too many customers are now re financing away via their adviser , you can't have it both ways.

Despite the banks claiming that their online refix process introduced for customers has been a good outcome for consumers it has clearly not been and was rightfully challenged by the mortgage adviser industry when first introduced by ASB. In many instances customers who are not engaging the services of a mortgage adviser don’t now receive any advice whatsoever around the refix process. How is this change instigated by the banks themselves promoting those “good customer outcomes” that the Financial Markets Authority expects and demands now from all financial service providers? Customers don’t have sufficient time now to make an informed decision. Previously the new rates been offered by banks were valid for up to 3 business days. They are now only valid for that same day. The banks still give new home loan customers 3 business days to decide which interest rate they want (when customers go direct) so why are those customers refixing their home loan essentially been told “decide today, or the rate may change on you”. Clearly the banks don't want customers shopping around or engaging a mortgage adviser to let them know what else is available in the market. This would seem to be a breach of consumer law in New Zealand i.e. limiting a consumer’s choice. Finally. If the customer is using a mortgage adviser that adviser no longer has the ability to get the bank in question to sharper their interest rates if necessary to match a competitor bank. The only option left open to the mortgage adviser to ensure that their customer receives a competitive offer is to refinance them to another lender, if it’s in the customer’s best interest to do so. The digital refix process has essentially allowed the banks to reduce the margins they previously had to offer customers using a mortgage adviser to retain their home loan business. Please tell me how is this a good outcome for consumers? P.S. If the Commerce Commission had any ability to understand the various industries that it is charged with reviewing it would realise that the online refix process instigated by the banks has been a massive step backwards for kiwi consumers and take appropriate action. Yeah, good luck that ever happening.
