Clawbacks Explained: Why You Might Get a Bill if You Switch Banks Too Soon

Getting a $5,000 cash contribution deposited into your account on settlement day feels like a welcome bonus. You can use it to help cover solicitor fees, pick up essential appliances, or leave it in an offset account to give your emergency savings an immediate boost.

However, bank incentives always come with conditions attached.

Banks do not hand out cash contributions out of generosity. They spend significant money acquiring new customers, and they want to ensure you stay long enough for the lending to become profitable for them. To guarantee that, lenders attach a 'clawback period' to the funds.

If you exit your mortgage before that agreed period ends—whether you sell the home, pay off the debt, or refinance to a competing bank—the lender will typically require you to repay a portion of that initial cash contribution.

Here is how New Zealand banks calculate those repayment bills, the timelines to keep in mind, and how to work out whether switching lenders actually stacks up financially.

How is a cashback clawback calculated?

A clawback is rarely an all-or-nothing penalty, but it is also not always a smooth daily countdown.

Depending on your lender's policy, your clawback will usually follow one of three calculation methods:

• The annual step-down: Common among several major retail banks, this formula reduces your penalty in large blocks every twelve months. For example, on a three-year policy, the penalty remains at 100% throughout your first year, drops to 66.6% in year two, drops to 33.3% in year three, and disappears completely once you pass the third anniversary.
• Monthly pro-rata: Some lenders calculate the reduction incrementally every single month across the term.
• Daily reducing: A handful of banks calculate the clawback down to the exact day the loan is discharged.

Because policies vary across lenders, checking your original loan agreement or speaking with your adviser before making any changes is always the best way to confirm your exact repayment formula.

The three-year versus four-year timeline

The duration of your clawback commitment depends entirely on which lender you drew down your mortgage with.

In New Zealand, banks generally fall into two broad camps:

• Three-year clawback lenders: The majority of mainstream trading banks apply a standard 36-month timeline.
• Four-year clawback lenders: Certain regional, non-bank, or specialist lenders require a slightly longer 48-month commitment before the cash contribution is fully yours to keep.

The real maths of refinancing: why cash isn't the whole story

Seeing a clawback bill on a settlement statement can feel like a bitter pill. But letting it trap you with an uncompetitive lender can sometimes cost you far more in wasted interest.

However, we need to be completely honest about the maths here.

How the trade-off works in the real world

Let’s look at a realistic scenario with a homeowner who has a $600,000 mortgage.

They are two years into a three-year clawback period, meaning they have 12 months left before the cash is completely theirs.

• The cost to leave early: Their current bank wants $2,000 of the original cash back, plus a solicitor will charge around $1,000 to handle the mortgage discharge and new registration. That is $3,000 in total friction to move.
• The new bank's offer: A competing bank offers a fresh $4,000 cashback, plus an interest rate that is 0.75% lower than what their existing bank is offering to refix.

Here is how an estimated scenario stacks up over those remaining 12 months:

The takeaway

That is how you evaluate a clawback: don't look at the cash in isolation. Look at the total cost of staying versus the total cost of moving over the time you have left.

A transparent look at adviser clawbacks

If you used a financial adviser or mortgage broker to arrange your initial home loan, there is another operational detail worth understanding.

Because mortgage advisers generally do not charge borrowers an upfront fee for standard residential lending, they are paid a commission directly by the bank after your mortgage settles.

However, if that loan is repaid or refinanced away within the first two years (typically 24 to 28 months), the bank claws back that commission from the adviser.

To cover the considerable administrative work, compliance reviews, and time invested in preparing your original mortgage, most advisory firms include a 'clawback recovery fee' within their terms of engagement. This fee is usually calculated on an hourly basis and capped at a clear, documented maximum.

How to manage this smoothly

Most borrowers never end up paying this fee. Because bank clawback policies typically span three to four years, most homeowners wait until the bank's clawback has reduced significantly before looking to move. By that point, the adviser's two-year window has often already expired.

If you are considering refinancing within the first two or three years, the most straightforward approach is to get in touch with the adviser who structured your original loan. If they manage your refinance to the new bank, they will almost always waive any recovery costs associated with the initial mortgage.

Making an informed decision

Balancing clawbacks, potential fixed-rate break costs, legal conveyancing fees, and new bank incentives is a straightforward mathematical exercise when you have all the figures laid out side by side.

At Home Loan Factory, we run these net-benefit calculations every week. We look at your current clawback, estimate any break fees, factor in legal costs, and compare them against the best cashback offers and interest rates in across our lender panel today so you know exactly where you stand.

Frequently asked questions

What is a mortgage cashback clawback?

A clawback is a contractual term applied by a lender requiring you to repay a portion of your initial cash incentive if you repay, refinance, or discharge your mortgage before an agreed period (usually three to four years) has passed.

Is a clawback calculated by month or by year?

While some lenders calculate clawbacks on a monthly pro-rata or daily schedule, several major New Zealand trading banks apply an annual step-down approach. Under this structure, your repayment amount stays fixed for twelve-month blocks and reduces on the anniversary date of your settlement.

Is a clawback different from a fixed-rate break fee?

Yes. A clawback is the repayment of an unearned cash contribution. A break fee (or early repayment adjustment) is a completely separate bank cost charged if you exit a fixed interest rate contract before its maturity date while wholesale market rates have dropped. If you refinance mid-term, you may encounter both.

Should I stay with my bank just to avoid paying a clawback?

Not necessarily. While paying a clawback requires upfront funds on settlement day, the fresh cash contribution and lower interest rates offered by a new bank will often outweigh the cost of the clawback, resulting in a positive net financial outcome over the life of your next fixed term.
