Mortgage Cashback Offers NZ 2026: Every Bank Compared

What a mortgage cashback actually is

A cashback (banks call it a “cash contribution”) is a lump sum paid into your account shortly after your new loan settles. It exists because winning a new mortgage customer is worth years of interest margin to a bank, so they compete upfront. Cashbacks apply to new purchases and to refinances — switching banks is the most common way Kiwis collect one.

How much do NZ banks pay in 2026?

Offers move constantly and are usually negotiated per-deal rather than advertised, but the shape of the market is stable:

• Percentage-based offers typically run from about 0.1% up to around 1% of the loan value, with the average settling near 0.7%. Aggressive campaigns have advertised more.
• Fixed-dollar offers for first home buyers are common — several thousand dollars on minimum loan sizes.
• Larger, cleaner loans get better offers. An 80%-LVR PAYE borrower with a $700k loan has far more negotiating power than a 95%-LVR borrower with a $300k loan.

Because offers are negotiated, two customers at the same bank can receive different cash. This is exactly where a broker earns their keep: we ask multiple banks to compete on both rate and cash for your scenario.

The clawback — read this before you take the money

Every cashback comes with a condition: stay with the bank for a set period, usually two to four years. Repay the loan or refinance away inside that window and the bank claws back the contribution — some pro-rata it, others recover the full amount. If you're planning to sell or restructure soon, a big cashback can turn into a debt.

Refinance maths: is switching for cash worth it?

A genuine refinance comparison nets everything off:

The cash is the headline, but the interest-rate saving over the next few years is usually the real prize. We run this calculation for clients before recommending any switch — sometimes the answer is “stay and renegotiate”, and your existing bank will often sharpen its pricing when it knows a broker is involved.

How to get the best cashback

1. Get your file in order — clean statements, stable income, LVR at or below 80% if possible.
2. Have a broker put your scenario to several banks at once; competitive tension raises offers.
3. Negotiate rate first, cash second — never accept a fat cashback that hides a soft rate.
4. Check the clawback period fits your plans before signing.

Frequently asked questions

Do all NZ banks offer mortgage cashbacks?

Most main banks pay cash contributions on new lending and refinances, but offers vary by campaign, loan size, and LVR, and most are negotiated rather than advertised. A broker can tell you what's realistic for your scenario this month.

Is a mortgage cashback taxable in NZ?

For ordinary owner-occupiers a cash contribution is generally treated as a discount on borrowing costs rather than income, but tax treatment can differ for investors and businesses — check with your accountant.

Can I get a cashback when refinancing to a new bank?

Yes — refinances are the classic cashback scenario. Just net off legal fees, any break fees, and any clawback your current bank will charge before deciding.

What happens to my cashback if I sell my house early?

If you repay the loan inside the clawback window (typically 2–4 years), the bank can recover some or all of the contribution. Ask for the clawback terms in writing before you commit.
