Green Finance
New Zealand's major banks offer preferential home loan top-up rates for EV purchases. Borrow at rates as low as 0–1% p.a. — a fraction of standard personal loan rates — simply by topping up your existing mortgage.

How it works
These aren't personal loans — they're structured as top-ups to your existing home loan. Because they're secured against your property, banks can offer dramatically lower interest rates than standard car finance.
The loan is added to your mortgage, meaning rates sit at 0–1% p.a. rather than the 12–18% typical of personal car loans.
All four banks support battery EVs (BEVs) and plug-in hybrids (PHEVs). Some also extend eligibility to heat pumps and solar.
The top-up rate is fixed for the agreed term (3–5 years), giving you certainty over repayments while you enjoy running cost savings.

Eligibility
You must already have a mortgage with the lender you're applying to. These products are not available to new-to-bank customers.
The EV must be a new or used battery electric vehicle (BEV) or plug-in hybrid (PHEV). Standard hybrids (HEVs) without a plug are typically not eligible.
You'll need a sale and purchase agreement or dealer invoice confirming the vehicle details and purchase price.
The top-up increases your mortgage balance. Your bank will assess your current LVR and serviceability as part of a standard top-up application.
If your mortgage is with Kiwibank, a non-bank lender, or you don't own a home yet, standard vehicle finance is still available. Talk to a mortgage broker or ask us about alternative options — we work with buyers in all situations.
Working with EV Quest
Getting your green loan sorted before you choose a car puts you in the strongest position. Here's how the process typically works when you buy through us.
Contact your bank's home loan team and request a green loan top-up pre-approval. This confirms your borrowing limit before you commit to a vehicle.
Once you know your budget, browse our current inventory or lodge a custom order for a specific make and model. We source primarily from Japan and will give you a full vehicle report.
For vehicles in transit, a refundable deposit holds your vehicle. We provide all purchase documentation your bank will need to finalise the top-up.
Once your bank approves and releases the funds, settlement is completed and your EV is yours. The top-up simply adds to your existing mortgage balance.
