Road user charges (RUC) explained for NZ drivers

Updated 4 Oct 2026

Road user charges (RUC) are how some vehicles pay towards New Zealand's roads instead of paying tax in the price of fuel. If you own a diesel, an EV or a plug-in hybrid, you buy RUC in advance for the distance you drive. If you own a petrol car, you pay fuel tax at the pump, though the Government plans to change that. Here's how it works.

In this guide

Who pays RUC

According to NZTA, you pay RUC if your vehicle:

  • weighs more than 3,500kg, whatever fuel it uses, or
  • weighs 3,500kg or less and is powered by diesel, electricity or any other fuel that isn't taxed at the source.

Some vehicles are exempt. NZTA's RUC exemptions page lists them, including some very light EVs.

The rate depends on the vehicle type and weight. NZTA publishes current RUC rates and transaction fees, along with a RUC calculator. Check there for current rates rather than relying on figures you see elsewhere.

Petrol vehicles

Most petrol cars, utes and vans don't pay RUC. Instead, fuel excise duty is included in the price of petrol, so you pay as you fill up. Standard petrol hybrids that can't be plugged in are treated the same way.

That may change. See the move to electronic RUC below.

Diesel vehicles

Diesel isn't taxed at the pump in the same way, so all diesel vehicles pay RUC, including light diesel cars, utes and vans. This is worth remembering when you compare a diesel's running costs with a petrol one: the fuel looks cheaper, but you pay RUC on top.

Heavy vehicles over 3,500kg pay RUC whatever their fuel, have higher rates, and need a hubodometer or approved electronic system to record distance.

EVs and plug-in hybrids

Light EVs and plug-in hybrids have paid RUC since 1 April 2024. NZTA's About RUC page explains:

  • Battery EVs, plug-in diesel hybrids and diesel hybrids pay the standard rate.
  • Plug-in petrol hybrids pay a lower rate, because they also pay fuel tax on the petrol they use.
  • Standard petrol hybrids that can't be plugged in don't pay RUC.

If you're thinking of buying one, our guide to buying a used EV or hybrid covers battery health and charging as well.

Buying and displaying RUC

NZTA's page on buying a RUC licence sets out how it works:

  • You pre-pay for distance in units of 1,000km, before you drive it.
  • You must buy a new licence before you've driven all the distance on your current one.
  • You can buy RUC online (up to six licences at a time), in the NZTA app, or from an agent. An administration fee applies to each licence.
  • Light vehicle licences (3,500kg or less) don't expire; they run until the odometer reaches the end distance.
  • Display the licence inside the windscreen on the passenger side, with the plate number visible from outside. If you buy online, you'll get a temporary label to print while the real one is posted.

You can check your current end distance online or in the NZTA app. NZTA may send reminders if it has your email address, and it can invoice you if you fall behind. For example, the odometer reading taken at a WoF shows whether you've driven past the distance you've paid for.

Some operators use eRUC, an electronic system that records distance and automates buying.

Buying or selling a RUC vehicle

RUC catches out a lot of private buyers and sellers. NZTA says:

  • Buyers: check the maximum distance on the RUC label against the odometer before you buy. If the licence isn't current, you can become responsible for the distance that hasn't been paid for, and NZTA won't get involved in a dispute between buyer and seller. You can check RUC online with NZTA's expiry check.
  • Sellers: it's against the law to sell a RUC vehicle without a current licence. RUC belongs to the vehicle and can't be transferred to another vehicle or refunded, so it's reasonable to factor unused distance into your price.

NZTA's buying a vehicle page also covers rego and WoF; see our guide to WoF, CoF and rego.

The move to electronic RUC

The Government plans to replace petrol tax with electronic road user charges for all vehicles. NZTA's page on replacing fuel tax with RUC says the changes would bring electronic licences, more ways to record distance, and post-pay or monthly billing.

At the time of writing, NZTA says no date has been set for moving all light vehicles onto RUC, and that the Minister expects legislation to be passed in 2026. Nothing changes for petrol car owners until the rules do, so check NZTA for updates rather than acting on rumours.

Frequently asked questions

Do petrol cars pay RUC?

Not at the moment. Petrol cars pay fuel excise duty in the price of petrol. The Government plans to move all vehicles onto electronic RUC, but no date has been set for light vehicles.

How much does RUC cost?

It depends on the vehicle type and weight, and rates change. Check NZTA's RUC rates page or its RUC calculator for the current figure for your vehicle.

What happens if I run out of RUC?

You must buy RUC before you use up your current licence. If you fall behind, NZTA can send you an invoice for the distance you haven't paid for, so keep an eye on your end distance.

Can I get a refund for unused RUC when I sell?

No. RUC stays with the vehicle and can't be refunded or transferred, so agree a price that reflects any unused distance.
