Clawbacks Explained: Why You Might Get a Bill if You Switch Banks Too Soon
A quick heads-up before we dive in: This article is strictly for general informational purposes and does not constitute financial, legal, or tax advice. Every situation is entirely unique, and bank lending policies change frequently. Before making any decisions about your property journey, it is highly recommended that you seek independent advice from a qualified financial adviser.
Getting a $5,000 cash contribution deposited into your account on settlement day feels like a massive win. You can buy new appliances, cover your solicitor fees, or just pad out your emergency fund.
But there is a catch.
Banks don't give away money for free. They invest heavily in acquiring your business, and they want to make sure you stick around long enough for the loan to become profitable for them. To guarantee this, they attach a "clawback period" to that cash.
If you break your mortgage before that period ends—whether you decide to sell the house, pay the loan off entirely, or refinance to a different bank—you are legally obligated to pay a portion of that cash back.
Here is exactly how New Zealand banks calculate those bills, the timeline you need to beat, and a calculator to check your own numbers.
How is a Clawback Calculated? (The Yearly Step-Down)
A clawback is rarely an "all-or-nothing" penalty, but it is also not usually a smooth daily countdown. Some New Zealand banks calculate your clawback using a yearly step-down policy, some monthly, and one (at time of writing) does indeed calculate daily. Check with your bank or adviser which cashback clawback formula your bank uses.
This means your penalty changes in big steps every 12 months, staying exactly the same price whether you are two months in or 11 months in.
If you have a 4-year clawback period, the bill stays at 100% for the first year, then drops by exactly 25% at the start of each new year.
If you have a 3-year clawback period, the bill drops by 33.3% at the start of each new year.
If you cross the threshold into a new year, your potential bill instantly drops. Once the final day of the period passes, you hit your final milestone card—the money is entirely yours to keep.
The 3-Year vs. 4-Year Divide
Not all lenders enforce the same rules. The length of your clawback period depends entirely on the specific bank you chose when you drew down your mortgage.
In New Zealand, banks generally fall into one of two categories:
The 3-Year Lenders: The majority of mainstream banks stick to a standard 36-month timeline, with the penalty reducing by a third each year.
The 4-Year Lenders: Certain regional or specialized banks require a slightly longer commitment of 48 months before the cash is completely yours.

Crunching the Net Gain via Refinancing
A clawback bill can look intimidating, but letting it trap you at a lender with uncompetitive interest rates is a massive mistake. Often, the math still works out heavily in your favor to break early and pay the penalty.
Why? Because of the Net Gain Analysis.
When your initial fixed-rate period ends (usually after 1 or 2 years), you have the opportunity to refinance your mortgage to a completely new bank. While your old bank will issue a clawback bill for breaking early, your new bank will almost always offer you a brand-new cashback alongside a lower interest rate to win your business.
To find out if switching works for you, you can run your specific details through our Advanced Refinance Calculator. It maps your current mortgage structure against the whole market to calculate your true net savings after all fees are settled.
The Strategy in Action: Let's say you are inside Year 2 of a 3-year clawback with your current bank. You originally received a $4,000 cashback.
The Penalty: Because you are in Year 2, your clawback bill is $2,667 (meaning you keep $1,333).
The Reward: You refinance to a new bank that offers you a fresh cashback of $5,000 plus a lower fixed rate.
The Net Result: You use the new bank's $5,000 to clear the $2,667 bill, leaving you with a pure $2,333 cash profit in your pocket, on top of the ongoing interest rate savings.
Another Consideration: Adviser Commission Clawbacks
If you used a mortgage adviser to set up your loan, there is one more detail to keep in mind.
Because advisers generally don't charge you an upfront fee, they are paid a commission by the bank once your loan settles. However, if you repay that loan or refinance to another bank within the first two years (usually 24 to 28 months), the bank will actually take that commission back from the adviser.
To cover the time and administrative costs of setting up that original mortgage, most advisers include a "clawback recovery fee" in their terms of service. This is usually calculated at a standard hourly rate and capped at a maximum amount (such as $3,000).
The good news: Most borrowers never actually have to pay this fee. Because the bank's cashback clawback usually lasts for 3 to 4 years, while the adviser's window is only about 2 years, the adviser's timeframe has typically already expired by the time most people decide it makes financial sense to switch banks.
How to avoid paying this fee: If you are thinking about refinancing and it has been less than three years, the easiest way to avoid unexpected bills is simply to talk to your original adviser before making a move. We recommend first contacting the adviser who set up your original loan to clarify any costs. If they end up handling your refinance for you, they will almost always waive any recovery fees from your old loan.
Don't Let the Bank Make the Rules. Run the Numbers.
Navigating clawbacks, break fees, and new bank incentives is a balancing act. One wrong move can cost you thousands, but timing the market right can put pure profit directly into your pocket.
At Home Loan Factory, we run these exact calculations every single day. We factor in your current clawback, projected break fees, and the top cashback offers available in the market right now to tell you definitively whether staying or switching is the right financial move.
Clawbacks & Cashbacks
What is a mortgage cashback clawback?
A clawback is a contractual penalty enforced by a bank if you repay, sell, or refinance your mortgage before a specific timeframe (usually 3 to 4 years) has elapsed. It requires you to repay a portion of the cash incentive you received when the loan was drawn down.
Is clawback calculated by month or by year?
While some niche lenders use a daily or monthly pro-rata calculation, the vast majority of New Zealand banks evaluate clawbacks by year blocks. Your penalty remains the same for the duration of the year and drops significantly on the anniversary date of your loan settlement.
Is a clawback the same thing as a break fee?
No. A clawback is the repayment of your initial cash incentive. A break fee is a separate financial penalty charged by the bank if you break a fixed interest rate before the agreed term has expired. It is possible to face both fees simultaneously if you switch banks mid-way through a fixed term.
Should I stay with my bank just to avoid a clawback?
Not necessarily. While you will have to pay a portion of your original cashback, refinancing to a new bank often yields a brand-new cashback offer that completely covers the cost of the clawback, while also securing you a lower interest rate.
