Road user charges (RUC): who has to pay, and what it costs
RUC is a fuel question, not just a "trucks and diesel" one — plug-in hybrids and EVs are in scope too, with their own split rates. Here's who's liable, how it's bought, and today's figures, direct from NZTA.

Who has to pay RUC
- ✓ Every vehicle over 3500kg GVM (gross vehicle mass), regardless of fuel.
- ✓ Every diesel-powered vehicle, regardless of weight.
- ✓ Since 1 April 2024: battery-electric and plug-in hybrid vehicles 3500kg or under too — NZTA's own words are that RUC applies to a vehicle "powered by: diesel, electricity, another fuel that's not taxed at source."
- ✓ A vehicle 3500kg or under that only uses petrol, CNG or LPG does not pay RUC — it pays fuel excise duty (FED) at the pump instead.
There's one real carve-out worth naming precisely: NZTA's own wording is "You don't have to pay RUC for an electric vehicle if it weighs 1000kg or less (very light electric vehicles), or over 3500kg (heavy electric vehicles)." So a light EV's actual RUC-liable window sits between those two weights, not "any EV, full stop."
How it actually works
RUC is bought in advance, by distance, not by the calendar. You buy a licence for your next block of kilometres, and the label shows the furthest distance the vehicle can travel on it — checked against the odometer, not a date. NZTA is explicit about the consequence of letting that run out: "If the licence isn't current, you become legally responsible for paying for any distance the vehicle has travelled without a licence." There's no fixed "expiry date" the way a WOF or rego has one — it runs out by the kilometre, whenever that happens to land.
What it costs (current, indicative)
| Vehicle | Rate | Source |
|---|---|---|
| Diesel, battery EV, or a diesel plug-in hybrid | $76.00 per 1,000km | NZTA |
| A petrol plug-in hybrid | $38.00 per 1,000km | NZTA |
| Admin fee — online or NZTA app | $12.44 per licence | NZTA |
| Admin fee — counter sales at an agent | $13.71 per licence | NZTA |

The petrol/diesel split on plug-in hybrids catches people out: a plug-in hybrid isn't one rate, it's two, and which one applies depends on the other fuel it burns — a petrol plug-in hybrid gets the reduced $38.00 rate because it's already paying fuel excise duty on its petrol, while a diesel plug-in hybrid pays the same full $76.00 rate as any other diesel vehicle. On top of the admin fee above, a separate transaction fee applies per licence too, and that also varies by how you buy it.
These figures are a snapshot, not a fixed price. NZTA reviews RUC rates periodically — confirm the current figure at nzta.govt.nz before you buy.

FAQ
Who has to pay road user charges in NZ?
Every vehicle over 3500kg GVM, regardless of fuel. For lighter vehicles (3500kg or under): every diesel vehicle, and — since 1 April 2024 — battery-electric and plug-in hybrid vehicles too, unless a specific exemption applies.
Do petrol cars pay RUC?
No. A vehicle 3500kg or under that only uses petrol, CNG or LPG doesn't pay RUC — it pays through fuel excise duty at the pump instead, which is why petrol vehicles aren't RUC-liable.
Do electric vehicles pay RUC?
Most do, since 1 April 2024 — but there's a weight carve-out. NZTA's own wording: "You don't have to pay RUC for an electric vehicle if it weighs 1000kg or less (very light electric vehicles), or over 3500kg (heavy electric vehicles)." So an EV's RUC-liable window is roughly 1000kg to 3500kg.
How much is RUC per 1,000km right now?
As of August 2026: $76.00 per 1,000km for diesel vehicles, battery electric vehicles and diesel plug-in hybrids. Plus an administration fee that differs by how you buy it — currently $12.44 online or via the NZTA app, $13.71 at an agent counter. Rates are reviewed periodically, so check nzta.govt.nz for the current figure before you buy.
Is a plug-in hybrid's RUC rate the same as a full EV's?
Not always — it depends on the plug-in hybrid's other fuel. A diesel plug-in hybrid pays the full $76.00 per 1,000km rate, the same as any other diesel vehicle. A petrol plug-in hybrid pays a reduced $38.00 per 1,000km, because it already pays fuel excise duty on the petrol it burns.
