How I Squeeze a Retention Offer Out of ASB Before Refixing

The first time I refixed a large mortgage through the app, I tapped the button, accepted the carded rate — the advertised interest rate with no negotiation — and moved on. That one click probably cost me a few hundred dollars in cash I never asked for. Banks don't advertise it, but they have a retention team whose whole job is to stop you walking to another lender when your fixed term ends. I didn't know that until a broker told me.

Why banks pay you to stay

A retention offer is a cash contribution or rate discount the bank gives you to refix with them instead of refinancing elsewhere. When I had a $540,000 loan coming off fixed with ASB a few years ago, I rang their home loan team directly. The person on the phone had authority to offer me roughly 0.3 percent of the balance as cash. That worked out to about $1,600, paid into my account a few weeks after the new fixed term started.

Cash contribution is the bank giving you money for staying. It's usually calculated as a percentage of the loan amount, and 0.2 to 0.4 percent is the typical range for a loan that size. The rate discount was smaller, maybe 10 or 15 basis points off the carded rate. A basis point is one hundredth of a percentage point, so 15 basis points is 0.15 percent. That doesn't sound like much, but on a $540,000 loan it trims a noticeable slice off the monthly interest bill.

The actual phone call

You don't need a script, but you do need the right number. Don't go through the general customer service line. Ask for the home loan retention team or the home loan specialists. I said something like: "I've got $540,000 coming off fixed next month. I'm looking at what other banks are offering, but I'd rather stay if you can sharpen your rate or give me retention cash." The person I spoke to came back with a better rate and the cash within ten minutes. No haggling. The whole call took less time than it takes to mow my front lawn.

The clawback catches people out

A clawback is a clause that says if you leave the bank within a set period — usually three years in New Zealand — you have to repay the cash contribution in full. That's the trade-off. If you take $1,600 and then refinance to another bank eighteen months later because they offer 0.5 percent cash, you'll hand back the $1,600 and possibly pay legal fees to move the mortgage. I always tell landlords to read that clawback period before they say yes. It's not a trap, but it changes the maths if you think you might sell or restructure debt within that window.

Is staying put worth it?

For a self-managed landlord with one rental, staying put is often the better deal. When I worked through the numbers on my own place, the cost of moving banks included a solicitor's fee to discharge and register the mortgage and a valuation if the loan-to-value ratio was tight. That was before I even counted the time away from my properties. If I was about to go on parental leave or my income had dropped, the new bank would want fresh payslips and bank statements anyway. That's a hassle a retention offer avoids entirely. The bank already knows your history.

If you've got a separate renovation loan fixed for a different term, moving everything to another lender means aligning those terms or paying break fees. That's more friction than most new landlords expect. A ten-minute phone call to retain what you already have is essentially free money now, even if the cash amount looks modest. The alternative is a stack of paperwork and a hard credit check for a cash offer that might not be any better.

Now, every time a fixed term comes up, I block ten minutes on my calendar to call the retention team. It's the highest hourly rate I've ever earned for doing nothing.
