Cash-Out Refinancing in NZ: How Releasing Equity Works

What it means in New Zealand

You owe $400,000 on a home worth $900,000. You refinance to a $500,000 loan and receive $100,000. That's a cash-out refinance. Kiwi lenders call it releasing equity, and it can be done by moving to a new lender or by borrowing more from the one you have, which is a mortgage top-ups.

How much you can release

Two limits apply, and the lower one wins.

Equity. For a home you live in, most lending is capped at 80% of the property's value. In the example above, 80% of $900,000 is $720,000, so the ceiling would be $320,000 of extra borrowing. Borrowing above 80% is restricted by the Reserve Bank's loan-to-value rules and usually costs more. Rental properties have a lower cap.Affordability. The lender tests whether you can repay the whole new loan at a rate higher than the one you'll actually pay, and applies the Reserve Bank's debt-to-income limits. Plenty of people have the equity and fall short here.

Lenders ask what the money is for

This surprises people. Lenders want a purpose and may ask for evidence, such as a builder's quote or the statements of debts being repaid. Purposes they're generally comfortable with include renovations, a deposit on another property, a vehicle, and consolidating other debts. They're wary of funding business losses, speculative investments, or living costs with no plan to repay.

Being specific helps. "$60,000 for a new roof and bathroom, quote attached" gets approved faster than "some spare funds".

The catch: you're borrowing over a long time

Mortgage money is cheap compared with car finance or a credit card. But if you add $40,000 for a car to a loan with 25 years left, you pay interest on that car for 25 years. Our usual advice is to put the new borrowing in its own loan split and repay it over a term that matches what you bought. Five years for a car, perhaps ten for a renovation.
