What is car loan refinancing?

The one-sentence version

A car loan refinance is a new loan that pays off your old one. The new lender settles your existing loan directly, your old contract ends, and from then on you make repayments to the new lender under the new terms. You keep the car the whole time.

People refinance houses constantly. Car loans work the same way, they're just talked about less. The loan you signed on a car yard on a Saturday afternoon is not necessarily the loan you'd sign today with time to compare.

Why people refinance a car loan

Four reasons cover almost everyone:

• The original loan was expensive. Dealer-arranged finance is convenient, and convenience has a price: the rate on the yard isn't always the rate your file deserves. If your loan started life next to a "sign here today" conversation, it's a strong candidate for a re-check.
• Your situation improved. Lenders price the person you were when you applied. If your credit history has grown, your income is steadier, or old defaults have aged off your file, a new lender assesses the person you are now.
• The repayments don't fit anymore. Refinancing can stretch the remaining balance over a longer term to lower each payment (you'll usually pay more in total: that's the trade), or shorten the term to be done sooner.
• The loan has expensive passengers. Add-on insurance, payment-protection products, and fees that were bundled in at signing can be left behind when the loan is replaced. Our guide to red flags in your current loan covers what to look for.

What actually changes, and what doesn't

Stays the same	Changes
Your car, your keys, your daily life	Who you repay
The amount you still owe (plus any break fee)	The cost built into the loan
Your obligation to insure the car	The repayment amount and/or the term
The car as security for the loan	The security registration on the PPSR: old one released, new one registered

That last row happens behind the scenes: car loans in NZ are secured, and the security interest is recorded on the Personal Property Securities Register. The lenders handle the swap. If you want the detail, it's in Secured loans and the PPSR.

The maths that decides whether it's worth it

A refinance makes sense when the total cost of the new loan, including any break fee on the old one, comes in under the total cost of staying put. Three numbers drive it:

1. What you still owe (the balance being refinanced),
2. What you're paying (your current repayment), and
3. How long you have left (the remaining term).

Those three numbers contain your loan's whole future: multiply the repayment by the number of payments left and you can see exactly what staying put costs. A new loan on the same balance and term, priced lower, costs less each week, and the gap compounds over the years remaining. The savings calculator does this arithmetic for you and shows the picture under 1%, 2%, and 3%-lower scenarios. It's an illustration, not a quote (the real numbers come from a lender assessing your actual file), but it tells you whether the question is worth asking.

What a refinance costs

Three possible costs, all knowable in advance:

• A break fee on your current loan. Some NZ loan contracts charge an early-repayment fee; many charge little or nothing. It's in your contract, and your lender must tell you the payout figure if you ask. Here's how to find yours.
• An establishment fee on the new loan. Lenders typically charge one; it's disclosed up front in the offer, so it's in the comparison before you sign anything.
• Our service: nothing. Leverage is free to use. The lender pays us a referral fee when a loan settles, and that fee doesn't change the rate you're offered. If you don't switch, nobody pays anything.

Where Leverage fits

You could ring six lenders yourself, fill in six applications, and compare six offers. Refinancing through Leverage compresses that: one two-minute application, one soft check to start, and your file goes to a panel of approved NZ lenders. We bring back the strongest offer so you can weigh it against staying put, with the break fee, if any, already in the picture. If the offer doesn't beat your current loan, keeping your loan is a perfectly good outcome and you've lost nothing finding out.

Leverage Finance is a lead-generation referral service, not a lender. All lending decisions, rates, and terms are determined by the lender assessing your application. Nothing on this page is financial advice. It's general information about how refinancing works.
