Getting a car loan at 18 in New Zealand

The short answer

At 18 you are old enough to borrow for a car in New Zealand with most lenders. Under 18, the picture is different: Consumer Protection says contracts with under-18s can be challenged unless the contract was fair and reasonable, so lenders mostly will not go there. Once you turn 18, the question moves from your age to your situation.

Three things decide it: income you can prove, a licence the lender will accept, and a loan you can afford. The fourth, credit history, is usually blank at 18, and that is not a mark against you. Lenders treat “no file” differently to “bad file”. Our first car finance guide gives the wider view. This page is about the specific problems of being 18.

What lenders look for at 18

Income and how long you have had it

Lenders want to see pay arriving regularly. A full-time job of a few months with payslips is far easier than casual shifts or a job that has just started. Some lenders publish an income minimum, and the figures we saw were in the range of $350 to $400 a week after tax. Others do not state one. Whatever the number, the real test is whether the repayment leaves you enough for rent, food, fuel and the other costs of running a car.

Part-time or casual work can still count. Bank statements showing a steady pattern over three months help a lot.

Your licence

Lender rules differ. One lender states that it accepts a full or restricted licence. Another lender’s guide says a valid learner licence is enough, but others will want more. Ask first. Your licence stage also affects how you can use the car:

• On a restricted licence you can drive alone between 5am and 10pm, and between 10pm and 5am only with a supervisor in the front seat.
• You can generally not carry passengers unless a supervisor is with you, with set exceptions such as a spouse or partner or children in your care.
• NZTA has announced changes to the learner and restricted stages from 25 January 2027, so check the NZTA site for the rules that apply to you.

If your friends are the reason you want a car, a restricted licence limits that.

Your deposit

At 18 a deposit does more work than almost anything else. It shrinks the loan, lowers the repayment and shows you can save. Even $1,000 to $2,000 changes how a lender reads you. If you have none, see no deposit car finance, and know it will cost more.

The car itself

For a secured loan the car is the security. Lenders look at its age, value and condition. One lender we looked at wants the car’s value to cover at least 70% of the amount borrowed, and a current warrant of fitness and registration. A very old or very cheap car can fall under a lender’s minimum loan size, and some lenders have a floor of several thousand dollars.

Your credit file

You probably have a thin file. If you have had a phone plan, a store account or buy-now-pay-later, check your free reports from Centrix, Equifax and Experian (formerly illion), because missed payments on any of them show up. See what credit score you need for how to read them.

A guarantor or joint borrower

If your income is modest or short, a parent or another adult with a good record can apply with you or act as guarantor. This often turns a decline into a yes. It also puts them on the hook if you stop paying, and it can show on their credit file. They should read the contract and be happy to carry that risk. Joint and guarantor car finance explains the difference.

A worked example (illustrative numbers only)

Say you want an $8,000 car and have $1,500 saved. You borrow $6,500.

• At an illustrative 14% over three years, repayments come to about $222 a month, or about $51 a week. You repay roughly $7,980 in total, so about $1,480 is interest.
• Stretch it to four years and the weekly cost drops, to about $41, but the interest climbs to about $2,000. Low weekly numbers cost more in total.
• Now add the running costs. Registration, a warrant of fitness, insurance, fuel and servicing can add up to a lot more per week than people expect. Insurance for young drivers can be high, so get quotes before you commit.

These are made-up numbers to show how it works. Real rates depend on the lender and your situation, and rates for a first-time borrower are often higher than for someone with a long record. Use the repayment calculator, then read the real cost of owning a car.

Alternatives that cost less

• Save longer. Six more months of saving can mean a smaller loan and a better rate.
• Buy cheaper. A reliable older car bought outright costs far less over time than a newer car on a loan.
• Buy with family help. A family loan on written terms avoids the interest. Put the terms in writing.
• Try a low-cost community loan. If you have a low income, Good Shepherd NZ’s Good Loans are no-interest, and some other microfinance lenders exist. Eligibility rules apply.

Red flags

• Dealer finance with a very low weekly figure and a large final payment. Ask for the total cost.
• Pressure to sign on the day. Take the contract home.
• Add-ons you did not ask for. Extended warranties and insurance bundled into the loan raise the cost.
• A promise of approval before anyone has looked at your income. Lenders must check that you can afford the repayments before lending. Be wary of anyone who skips that.
• A car with money owing on it. Run a PPSR check first.

Mistakes we see at 18

• Applying at several lenders in a week. Each hard check is a mark on a file that is still thin. Do one soft check first, and apply only where you have a realistic chance.
• Choosing the car before the budget. Fall in love with a car first and the loan has to stretch to fit it. Fix the weekly ceiling, then shop.
• Forgetting insurance. Many lenders require the car to be insured with them noted as an interested party. A quote on the exact car, with your age and licence stage, can change which car makes sense.
• Counting on overtime or shifts that are not rostered. Lenders use steady pay, so borrow against that and treat extra hours as a bonus.
• Letting a parent sign without a conversation. A guarantor is not a formality. Agree in advance what happens if a payment is missed, and keep them updated.
• Skipping the pre-purchase check. A used car from a private seller has no dealer behind it. A mechanical inspection and a PPSR check are cheap against a $6,000 mistake.

Being 18 with a loan that is paid on time is also how you build the credit file you do not have yet. A small loan, repaid steadily, usually helps your next application. A loan that goes into arrears at 19 can follow you for years.

What the application will ask you

Expect an application form to ask more than your age. You will usually be asked to confirm you are over 18 and have regular income, your licence type (learner, restricted or full), and whether you expect big changes to your finances in the next year. It will ask for your address and employer, and many forms ask for the previous ones if you have been at the current ones for under three years. It will also ask you to list what you already owe, including phone plans, buy-now-pay-later accounts and any fines, and some lenders check for unpaid fines.

Ask for a free copy of your credit file before you apply, and if it shows a debt you do not recognise, sort it out first. Sorted suggests checking a few months ahead so there is time to fix errors. If a parent or other adult is joining as a co-borrower, remember that they share liability for the whole loan, so they should read the contract with you.

How Fair Finance helps

Fair Finance is a referral service, not a lender. One application and one soft credit check go to a panel of approved New Zealand lenders, so you can see where you stand without a hard check at each. The lender makes its own decision, case by case. We are paid by the lender only if a loan settles, and that never changes your rate. If a smaller loan or a cheaper car is the better move, we will say so.
