Car finance, explained.
Straightforward guides to how car finance actually works in New Zealand. No jargon, no sales pitch, just the mechanics: how a loan is structured, how the rate is set, and what the paperwork means before anyone signs anything.
The basics
How car finance works in NZ
What actually happens between walking into a yard and making the last payment on a New Zealand car loan.

Dealer finance vs bank vs broker
A dealer, a bank and a broker will each sell you much the same secured loan. What differs is who sees your application, and what else is being negotiated at the same time.
Read the guideThe basics
Secured vs unsecured car loans
Whether the lender holds your car as security is the one difference, and it sets the rate, the risk and the paperwork.
Read the guideRates
Fixed vs floating car loan rates
Nearly every car loan here is fixed for the whole term, which is why you can know the weekly cost before you sign anything.

Car loan deposit explained
Every dollar you put down is a dollar that never accrues interest, and it moves your rate, your total cost and your equity all at once.

CCCFA car lending rules
The consumer-credit rules sitting behind every New Zealand car loan application, in plain English, as education rather than advice.

Balloon payments and residual value
A balloon parks a chunk of the loan at the end of the term. Your weekly payment drops, and a lump sum waits for you at the finish.

Trade-in vs private sale
Trading in or selling privately splits the same job very differently, and the split matters most when there's still a loan on the car.

Financing a car vs paying cash
Cash costs you interest you never pay. Finance costs you a buffer you get to keep. Both are defensible, and the numbers only settle half of it.

What lenders check on a car loan
Every check a lender runs is working toward two questions the law makes it answer. Can you afford this, and does it suit you.

How to refinance a car loan
When refinancing an existing car loan actually lowers what you pay, and where the maths quietly works against it.
Read the guideWhy these guides exist
Understand the loan before you take it.
Most people arrange car finance a handful of times in their life, often years apart, and usually under time pressure with a car already picked out. That is exactly the situation in which a weak understanding of how the loan works costs money. A rate that looks fine in isolation can carry heavy fees. A longer term that lowers the weekly payment can quietly add thousands in total interest. A dealer number offered at the desk can look competitive without a benchmark to compare it against.
These guides are here to close that gap. Each one takes a single part of the car-finance picture and explains it in plain New Zealand terms, using realistic figures and the actual rules that apply here (the CCCFA responsible-lending framework, the FMA's oversight of financial conduct, and the way credit reporting works through Centrix, Equifax, and Experian). They are educational, not advice. Nothing here tells any particular reader what to do, because the right answer depends on the borrower, the car, and the budget. What the guides do is describe how the mechanics work, so a lender's quote or a calculator result makes sense in context.
The set covers the foundations first: what a car loan is, how it differs from an unsecured personal loan, and how the interest rate is actually built. From there the guides branch into the choices that change the total cost, such as the size of a deposit, the length of the term, and where the finance comes from. Read them in any order. Each stands on its own, and each links through to the calculator so any figure mentioned can be tested against a real purchase price.
Know the mechanics? Run the numbers.
Every guide links back to the calculator. A price, a rate and a term, and the weekly cost is there. When you are ready, our finance partner compares NZ lenders for a formal estimate.
