When you take out a new home loan or move to a different lender, you will almost certainly hear the term "cashback."
Also called a cash contribution or incentive, a cashback is simply a lump sum of money a bank pays into your account on settlement day to say thanks for choosing them.
Getting a few thousand dollars when you move into a home is a great perk. It helps take the sting out of moving expenses, solicitor bills, or setting up the house. But this money always comes with strings attached, and it pays to know how the rules work before making any decisions.
Here is how cashbacks work in New Zealand, how clawback rules operate, and how to tell if an offer actually leaves you better off.
Why do banks offer cashbacks?
Banking in New Zealand is competitive. Lenders use cashbacks for two straightforward reasons:
- To win your business: An upfront cash payment is the easiest way for a bank to stand out and convince you to pick them over the bank down the street.
- To keep you around: It costs a bank real time and money to set up a new mortgage. They want to make sure you stay with them long enough for the loan to make commercial sense.
To protect their spend, banks include a rule in your loan contract called a clawback period.
How the clawback rule works
A clawback clause is an agreement that you will keep your home loan with that bank for a minimum amount of time—usually three to four years.
If you break that agreement early—by switching to another bank, paying the loan off completely, or selling the property—the bank will ask for some or all of that cash back.
The good news is that banks have become much fairer with how they calculate this. You will rarely see a lender demand 100% of the money back if you leave after a couple of years. Today, clawbacks generally work in one of two ways:
- Staggered yearly steps: The amount you owe drops in chunks on each anniversary of your loan (for example, having to repay 100% in year one, dropping to 50% in year two).
- Monthly or daily reductions: Many lenders now reduce what you owe month by month, or even day by day. This means if you leave after two and a half years, you only pay back the small, unused portion of the time remaining.
Once your clawback period is fully finished, the money is yours for good. You can change lenders, sell, or restructure your loan without paying a single dollar back.
How much cashback can you get?
Cashback offers move up and down all the time depending on how actively banks are competing for new business. Standard offers are typically calculated as a percentage of your total borrowing—usually between 0.5% and 1.25% of the loan balance.
The bank decides the final percentage based on three things:
- Your deposit size: Borrowers with a standard 20% deposit (or more) represent lower risk and get the top cashback tiers. If you have less than a 20% deposit, percentage-based offers are usually lower or unavailable.
- Your total loan size: Because it is a percentage, a larger mortgage gets a larger dollar figure.
- Your loan setup: Some facilities, like revolving credit accounts or offset splits, might not be counted toward the eligible total by certain lenders.
The First Home Buyer exception: flat $5k offers
While standard cashbacks scale directly with loan size, banks often treat first-home buyers differently.
Lenders regularly run special First Home Buyer campaigns with flat cash payments—frequently around $5,000.
The huge advantage here is that these flat offers often apply to buyers with less than a 20% deposit, including those using the Kāinga Ora First Home Loan scheme. They also apply to smaller loan sizes (such as $200,000 to $300,000) that you might see in regional areas or when a buyer has built up a massive deposit through KiwiSaver.
Why that matters on smaller mortgages
The real comparison: cash vs your interest rate
It is very easy to get excited by a large upfront cash offer, but the cash is only half the story. You have to look at the interest rate that comes with it.
Take this example on an $800,000 mortgage fixed for two years:
- Bank A: Offers a $6,000 cashback, but their two-year fixed rate is 6.25%.
- Bank B: Offers a smaller $2,500 cashback, but gives you a sharper two-year fixed rate of 5.99% (a 0.26% difference).
Over those two years, that 0.26% rate difference at Bank A will cost you around $4,100 in extra interest payments.
Take that extra interest off the bigger cashback, and Bank A’s real advantage drops to $1,900. Bank B’s lower cashback combined with their sharper interest rate actually leaves you hundreds of dollars better off overall.
Never judge a loan on the cashback alone. The goal is always to find the lowest total cost over the life of your loan.
Should you switch banks to get another cashback?
Once your three-to-four-year clawback period ends, you might wonder if it is time to switch banks and collect a new cashback.
As consumer advocates frequently highlight, the "loyalty tax" in New Zealand is real—banks often reserve their sharpest pricing and cash incentives for brand-new customers, leaving loyal existing customers paying higher rates.
However, jumping ship purely for a cashback payment is not always the right move. Refinancing involves real costs, risks, and benefits: you usually need to pay solicitor fees to discharge the old mortgage and register the new one, and there can be fresh valuation costs. Those legal bills quickly eat into the new cash you receive.
The smart way to review your options
The best approach is to use the end of your clawback period as a strategic review point.
When your fixed rates are coming up for renewal, we go back to your existing lender and ask them to match the market. Sometimes, they will come to the table with sharp interest rates and a modest "retention cashback" to keep your business. This gives you a great outcome without the hassle or legal costs of switching.
But if your current bank refuses to offer a competitive rate, or if their internal policies are stopping you from restructuring your loan the way you want to, that is exactly when we look at moving. We run the numbers across our comprehensive lender panel, factoring in the legal costs, the new interest rates, and the new cashback offers, to ensure that if you do switch, you end up significantly better off.
