NZ Car Loans Compared: The Rate Is Only Half the Cost
Harmoney starts at 7.99% p.a., while bank rates reach 13.90%. Fees, loan terms and credit rules can change the real cost.
Quick Picks
Best overall: Harmoney Car Loan for borrowers with clean credit who want a low starting rate and a soft quote check.
Best specialist lender: UDC Personal Vehicle Finance for buyers who prefer secured vehicle finance from a dedicated lender.
Best for imperfect credit: Instant Finance when bank approval is unlikely and speed matters more than the lowest rate.
Car finance ranges from 7.99% to 29.95% p.a. across these listings. That spread matters: on NZ$20,000 over five years, the difference between a low-rate offer and a high-risk rate can run into thousands of dollars before fees.
Rates and terms shown are representative. Your actual rate depends on your credit profile and circumstances. This is not financial advice — always read the lender's terms before applying.

Lowest rates: the gap is real, but approval is selective
The cheapest advertised rates sit with online and specialist lenders, not the major banks. That does not mean every applicant receives the headline figure. Credit history, vehicle type, loan amount and term can all move the final rate.
One useful detail is easy to miss: Harmoney's quote check is described as not affecting your credit score. That lets a strong applicant test pricing before committing to a hard application. A low rate is valuable, but only if the lender's eligibility rules fit your file.
Harmoney Car Loan
Harmoney has the lowest listed starting rate at 7.99% p.a., plus a soft quote check that does not affect your credit score. The loan is unsecured, so the car is not used as security, and terms run for three, five or seven years. That flexibility comes with a sharp warning: rates can reach 24.99%, and applicants need NZ or Australian citizenship with no defaults on their credit file. Best for a borrower with clean credit who wants to compare a likely rate online before a full application.
UDC Finance Car Loan
UDC starts at 8.55% p.a. and focuses specifically on vehicle finance, rather than offering a general personal loan. Its one-to-five-year terms suit buyers who want the debt cleared quickly, although the shorter maximum term can mean higher repayments than a seven-year bank loan. The final rate depends on the vehicle and your credit profile. Best for a buyer financing a qualifying car who prefers a specialist lender and can handle a repayment term of five years or less.
Harmoney wins on the headline rate, while UDC offers a more vehicle-specific structure. MTF sits between them on price, but its dealer-only route changes the application experience: you generally encounter the lender through a broker or dealership rather than shopping independently online.
MTF Finance Car Loan
MTF Finance advertises rates from 8.95% p.a., below every major-bank rate in this comparison. The lender's nationwide broker and dealer network can make it convenient at the point of purchase, but that is also the limitation: you do not get the same direct shopping process as Harmoney. Fees may apply, and the rate depends on your credit profile. Best for a good-credit buyer already purchasing through a participating dealer who wants a non-bank rate checked during the sale.
AA Money Car Loan
AA Money quotes a 9.40% to 12.15% p.a. range and accepts both new and used vehicles, with a minimum loan of NZ$5,000 and terms up to 60 months. The upper end of that range is still below ANZ's 13.90% standard rate, but the five-year cap can make monthly repayments heavier than a seven-year alternative. Best for a buyer borrowing at least NZ$5,000 who wants a recognised brand and a clear online application for a new or used car.
AA Money gives up some rate certainty in exchange for a range, while MTF puts more of the process in the dealer's hands. Both can beat the big banks, but neither removes the need to ask about establishment, broker or administration fees. A lower advertised rate can lose its edge once upfront costs are added.
Bank loans: simpler pricing, higher starting cost
The major-bank offers are easier to understand. Westpac lists 12.90% p.a., ASB 12.95% and ANZ 13.90%, with fixed repayments and familiar banking infrastructure. The price of that simplicity is substantial: ANZ's starting rate is 5.91 percentage points above Harmoney's advertised starting rate.
Bank eligibility also matters. Westpac and ASB require existing customers according to the supplied listings, narrowing access before credit assessment even begins.
Westpac Car Loan
Westpac's 12.90% p.a. fixed rate is the lowest of the big four bank offers listed here, and there are no early repayment fees. The five-year maximum term is shorter than ANZ or ASB, so repayments may be higher even when the rate is lower. The supplied Westpac page currently returns a page-not-found message, so applicants should verify the live product terms directly before relying on the listing. Best for an existing Westpac customer who wants a fixed bank loan and plans to repay within five years.
ASB Car Loan
ASB's 12.95% p.a. fixed rate is only 0.05 percentage points above Westpac's listed rate, but ASB allows terms up to seven years. That can reduce the required monthly payment, although a longer term usually means paying interest for longer. The listing says borrowers must be ASB customers and cannot choose a risk-based rate. Best for an ASB customer who values predictable repayments and needs up to seven years to keep the monthly amount manageable.
ANZ Car Loan
ANZ charges a single fixed rate of 13.90% p.a. on personal loans, with borrowing from NZ$3,000 to NZ$50,000 and terms up to seven years. There is no application fee or early repayment fee, which helps offset some of the higher interest cost, but the rate is not risk-based: a strong borrower does not receive a cheaper tier. Best for an ANZ customer borrowing NZ$3,000–NZ$50,000 who prioritises a fee-free application structure over the lowest available rate.
The bank group is not automatically poor value. A borrower who repays early may benefit from no early repayment fees, and a seven-year term can prevent an unaffordable monthly bill. Still, a longer term should not be used to disguise a loan that only works on paper. Compare the total repayment, not just the instalment.
Speed and credit access: paying more can be the wrong kind of convenience
Instant Finance is the outlier. Its rates begin at 9.95% p.a. but can reach 29.95%, with an establishment fee of NZ$100–NZ$220 and a NZ$3 administration fee per instalment. That is a very different proposition from Harmoney's low-rate offer, even though both advertise online applications.
The reason to consider it is access. The listing specifically says it accepts borrowers with imperfect credit and offers quick online approval. For someone who would otherwise be unable to buy a necessary vehicle, approval can have practical value. The maths still needs to be severe: a long 84-month term can make the payment look smaller while extending the interest bill.
Instant Finance Car Loan
Instant Finance is the clearest access-first lender in the list, offering fixed rates from 9.95% to 29.95% and loans from NZ$2,000 to NZ$50,000. The establishment fee and NZ$3 per-instalment administration fee need to be included in the total cost, not treated as minor extras. An 84-month maximum term may lower the scheduled payment but can keep the debt running for seven years. Best for a borrower with imperfect credit who needs a vehicle and has checked that the higher rate still fits their income.
That access comes with the widest pricing risk in the comparison. A borrower who qualifies for Harmoney, UDC or MTF should price those first; Instant Finance makes more sense after cheaper routes have been ruled out, not before.
What should you choose?
Choose Harmoney if you have clean credit, no defaults and want to see an online quote without affecting your credit score. Its 7.99% starting rate is the strongest headline figure here, but ask for the actual rate rather than assuming you will receive it.
Choose UDC if the vehicle itself is central to the finance and you can manage a one-to-five-year term. Choose MTF if you are buying through a dealer and have good credit, but confirm every fee before accepting the broker-arranged offer.
Choose AA Money for a NZ$5,000-plus new or used vehicle loan with a five-year limit. Choose Westpac or ASB if you already bank there and prefer fixed repayments, with Westpac slightly cheaper on the listed rate and ASB offering the longer maximum term.
Choose ANZ for a simple fixed loan with no application or early repayment fee, not because it has the lowest rate. Choose Instant Finance only when flexible credit criteria and quick approval outweigh the possibility of a rate as high as 29.95%.
