Car finance in New Zealand: the complete, plain-English guide
Car finance in NZ isn't complicated once someone explains it straight. You borrow to buy a car, usually secured against the car itself, and repay it with interest over a set term. The catch is that where you get that finance, and how you shop for it, can change what you pay by thousands. Here's everything that matters, in plain English.
How car finance actually works
A car loan is money you borrow to buy a vehicle, repaid in regular instalments over a term, usually one to seven years, with interest on top. Most car finance in New Zealand is secured against the car, which means the lender can repossess it if you stop paying. Because there's security, secured car loans usually carry lower rates than an unsecured personal loan.
Three numbers decide what you actually pay: the amount you borrow, the interest rate, and the term. A longer term lowers the weekly payment but costs more in total interest. Our repayment calculator lets you feel that trade-off in a few seconds.
Where to get it: dealer, bank, or broker
There are three main routes, and the difference between them is where a lot of people quietly lose money.
- Dealer finance. Arranged right there at the yard. Convenient, and sometimes there's a genuine promotional rate. But dealers can also add a margin to your interest rate for arranging the loan, and bad-credit customers get marked up the most.
- A bank or personal loan. Often the cheapest option if you have good credit and time to apply. Less flexible on imperfect credit.
- A broker or referral service. Compares several lenders for you. The good ones save you money and hard credit checks; the point is you're not stuck with whatever the dealer offers.
Fair Finance is the third kind. We're not a lender and not a dealer. We compare our lender panel and pass you the fairest rate they'll offer, with one soft credit check instead of five hard ones.
What affects your interest rate
- Your credit history. Stronger credit, lower rate. See bad credit car finance if yours is imperfect.
- Your deposit. More deposit, less risk, usually a better rate.
- The car. Newer and more reliable is easier to finance than very old or high-kilometre.
- Secured vs unsecured. Secured against the car is generally cheaper.
- The lender. This is the big one people miss: two lenders can price the same file completely differently.
What you'll need to apply
For most lenders, you'll need to be a New Zealand resident aged 18 or over, with proof of income (payslips, or three months of bank statements if you're self-employed or on casual income), ID and a driver licence, and the details of the car you're after. A deposit strengthens your application but isn't always required.
Your rights as a borrower
Consumer credit in New Zealand is regulated under the Credit Contracts and Consumer Finance Act (CCCFA). As of 1 July 2026, the Financial Markets Authority (FMA) is the conduct regulator for consumer credit. Lenders must lend responsibly, disclose the full cost clearly, and not mislead you. If a deal feels rushed, hidden, or too good to be true, that's your cue to slow down. You can read your rights at consumerprotection.govt.nz.

Common questions
What's the difference between dealer finance, a bank loan and a broker?
Dealer finance is arranged at the yard and is convenient, but the rate can be padded for arranging it. A bank or personal loan can be cheaper if you have good credit and the patience to apply. A broker or referral service compares multiple lenders for you. Fair Finance is a referral service: we compare our panel and pass you the fairest rate, without the dealer markup.
What interest rate should I expect on a car loan in NZ?
It depends heavily on your credit, deposit, the car, and whether the loan is secured. Rates commonly start around 9.95% p.a. for stronger applicants and rise from there. Bad credit means a higher rate, but how much higher varies a lot between lenders, which is why comparing pays off.
What do I need to apply for car finance?
Generally: you're a New Zealand resident aged 18 or over, with proof of income (payslips, or three months of bank statements if self-employed), ID and a driver licence, and details of the car. A deposit helps but isn't always required.
What is a secured car loan?
A secured loan uses the car itself as security, so the lender can repossess it if you default. Secured loans usually have lower rates than unsecured personal loans. Most car finance in NZ is secured against the vehicle.
Does applying for car finance affect my credit score?
A hard credit check can lower your score slightly, and several in a short time can add up. A soft check, like the single one Fair Finance runs across its panel, doesn't affect your score at all.
