The short answer
How each one stacks up
| Petrol | Hybrid | Diesel | Electric | |
|---|---|---|---|---|
| Best suited to | Low kilometres, tight budgets | Town and commuting, stop-start traffic | Long distances, towing, utes and SUVs | Home charging, predictable daily distances |
| Running costs | Highest fuel use per km | Low fuel use; no road user charges | Cheaper fuel, plus $76 per 1,000 km RUC | Cheapest energy at home, plus $76 per 1,000 km RUC |
| Watch for | Older engines' servicing history | Battery health on older cars | Short trips clogging the diesel particulate filter | Battery state of health and real-world range |
| Resale | Steady and predictable | Strong for popular models | Strong for utes and towing SUVs | Depends heavily on battery health |
RUC rates from MoneyHub. A plug-in petrol hybrid pays a reduced $38 per 1,000 km, because it also pays fuel tax at the pump.
How do road user charges affect the choice?
Road user charges (RUC) are how diesels, EVs and plug-in hybrids pay for the roads, by the kilometre instead of at the pump. EVs have paid them since 1 April 2024.
A regular hybrid like an Aqua or Prius pays none, because its fuel tax is already in the petrol price. That's a big part of why hybrids work so well for town drivers.
At 11,500 km a year, $76 per 1,000 km comes to around $900 in RUC. That narrows the gap between an EV and a hybrid. If you drive a lot, it narrows it further, so do the sums on your own kilometres.
The questions a carfinder asks you
We don't start with the fuel type. We start with how the car will actually get used.
- How far do you drive in a typical week? Mostly under 50 km a day points toward hybrid or EV. Regular long trips point toward diesel or a hybrid.
- Where does the car sleep at night? A garage or driveway with power makes an EV practical. Street parking makes it harder.
- Do you tow anything? A boat, caravan or trailer narrows it quickly toward diesel.
- How long will you keep it? The longer you keep it, the more running costs matter and the less the purchase price does.
- What's the budget, all in? Price, plus insurance, servicing and a few years of running costs.

Not sure which one suits you?
Answer a few questions about how you drive. A carfinder will pick 3 cars that fit, with why each one made the list.
What to check before you commit
Each type has one thing worth checking above everything else.
Hybrid: the battery. Hybrid batteries typically last 8 to 12 years. On an older car, get a battery health test. A replacement for a small hybrid runs from about $900 reconditioned to $4,000 new.
Diesel: how it's been driven. Diesels with a particulate filter need regular longer runs to keep it clear. A diesel that's only done school runs can come with a filter bill.
Electric: the battery's state of health. Ask for a report showing remaining capacity, and check the real-world range against your longest regular trip, with room to spare in winter.
Petrol: the basics. Service history, how it drives, and whether it's on the stolen cars list. The Toyota Aqua article covers that last one.
The short version
- Mostly town driving: start with a hybrid
- Long distances or towing: start with a diesel
- Home charging and predictable trips: look hard at an EV
- Low kilometres and a tight budget: petrol is fine
Common questions
How long do hybrid batteries last?
Typically 8 to 12 years, depending on use and climate. On an older hybrid, a battery health test tells you how much life is left before you buy.
Is a used EV a risk because of the battery?
It can be, which is why the battery's state of health matters more than the odometer. A report on remaining capacity tells you whether the range will still suit you in a few years.
How do road user charges affect diesels and EVs?
Both pay $76 per 1,000 km for light vehicles. Plug-in petrol hybrids pay $38. Regular hybrids and petrol cars pay none, because their road tax is in the fuel price.
Is a hybrid worth it in NZ?
For most town and commuting drivers, yes. The fuel savings are biggest in stop-start traffic, and there are no road user charges.
Can a carfinder help me decide between two?
Yes. Tell us the two you're weighing up and how you drive. We'll tell you which one suits you better, and why.
