EV road user charges are going up: what you'll actually pay
The NZ Angle
New Zealand has charged road user charges on light electric vehicles since 2024, when the government ended the RUC exemption that had been in place since 2009. From 1 August, NZTA is lifting the rate for light EVs from $76 per 1,000km to $82 per 1,000km. For plug-in hybrids like the Aqua PHEV and Outlander PHEV, the rate is calculated differently because they also burn petrol, which already carries a fuel excise levy baked into the pump price. The practical upshot is that a Leaf owner doing 15,000km a year will now pay $1,230 in RUCs annually, up from $1,140. That is a $90 increase year on year, not ruinous, but real money when you factor in that the Clean Car Discount ended in 2023 and there is no longer a subsidy cushioning the cost of going electric. Canterbury buyers doing higher annual kilometres, which is common when you are commuting from Rolleston or Rangiora into the city, feel this more than most. The RUC system requires you to pre-purchase distance in blocks, and unused distance does not expire, so buying ahead of a rate rise is a straightforward way to lock in the lower rate.
NZTA's revised RUC rates for light electric vehicles take effect 1 August. Here's what Leaf and Aqua PHEV owners will pay, how to buy ahead, and whether EVs still make sense.
NZTA confirmed the new RUC rates for light electric vehicles in late June, with the increase taking effect 1 August. The rate moves from $76 to $82 per 1,000km for battery electric vehicles. Plug-in hybrids are rated differently and sit at $53 per 1,000km for their electric component, though owners still pay fuel excise on the petrol they burn.
To put that in plain terms: a Nissan Leaf owner doing 18,000km a year will pay $1,476 annually in RUCs under the new rate, versus $1,368 under the old one. The difference is $108. Over three years, that is $324 extra compared with what you would have paid if the rate had stayed put.
How to buy ahead of the rate rise
RUC licences are bought in advance through NZTA's online portal or at any AA centre. You pre-purchase a block of kilometres, and the licence is tied to your odometer. Critically, unused kilometres carry over. There is no expiry.
If your Leaf currently has, say, 3,000km remaining on its RUC licence, you can log in before 1 August and purchase another block at the current $76 rate. That distance sits in reserve until you need it. The only limit is practical: you cannot stockpile 100,000km of licences at the old rate because the system requires your current odometer reading to match what is on the licence. You can buy ahead, but only in a way that your actual mileage makes plausible. In practice, most owners can realistically lock in 10,000 to 15,000km at the current rate before the deadline.
For plug-in hybrid owners on the $53 rate, the same logic applies. Check your remaining distance this week and top up if you are running low.
What EVs now cost to run against a comparable petrol car
The comparison that matters for most buyers is a 2018 to 2020 Nissan Leaf against something like a 2018 Toyota Corolla hybrid or a naturally aspirated hatchback in the same $18,000 to $24,000 bracket.
A Leaf doing 15,000km a year at $82 per 1,000km pays $1,230 in RUCs. Home charging at average residential electricity rates around 30 cents per kWh, and assuming the Leaf's real-world consumption of roughly 18 kWh per 100km, adds about $810 in power costs. Total running cost for energy plus RUCs: around $2,040 a year.
A 2018 Corolla hybrid doing the same distance at, say, 5.0L/100km and petrol at $2.70 a litre costs roughly $2,025 in fuel. No RUCs on top because petrol excise covers it. That is nearly identical.
A non-hybrid petrol Corolla at 7.0L/100km uses about $2,835 in fuel over 15,000km. The Leaf still wins there by a meaningful margin.
The honest caveat is that battery condition matters enormously in a used Leaf. A 2018 40kWh Leaf with a healthy battery will do fine. A 2015 24kWh example with degraded cells will cost you more in charging time, frustration, and possibly a battery replacement that runs $5,000 to $10,000 through a specialist. Check the battery health report before you buy. A good seller will have one.
Servicing costs on a Leaf are genuinely low. No oil changes, no timing chain, no exhaust work. Budget around $300 to $400 a year for a WoF, brake fluid, cabin filter, and tyre rotation. Tyres are standard 215/50R17 on most variants and are not exotic.
The Aqua PHEV is a different proposition. It is more expensive to buy, $22,000 to $28,000 for a tidy 2018 to 2020 example, and running costs sit between a full EV and a petrol car depending on how much of your driving you do on electric range. If you are mostly doing short urban trips and charging at home each night, the economics are good. If you are regularly driving Christchurch to Timaru and back without charging, you are essentially running a small petrol car with a heavier kerbweight.
Whether the numbers still stack up
The RUC increase does not fundamentally change the case for buying a used EV in 2025. The rate has gone up, but it was always going to. When the exemption ended in 2024, the government signalled this was a temporary introductory rate. Buyers who factored that in are not surprised. Buyers who assumed $76 forever are feeling the pinch.
For a Canterbury buyer doing genuine kilometres, the Leaf is still cheaper to run than a comparable petrol car at current fuel prices, even after the rate rise. That gap narrows if petrol drops below $2.40 a litre, or widens if it creeps back toward $3.00. At current rates, the maths favour the EV for anyone doing more than about 12,000km a year.
What the RUC increase does affect is the break-even point on purchase price. If you are paying a $4,000 to $6,000 premium for a Leaf over an equivalent petrol hatchback, you now need slightly more kilometres to recover that difference through fuel savings. At 15,000km a year, you are still there inside two years. At 8,000km a year, it is a much closer call.
Buy ahead if you can before 1 August. After that, just factor $82 per 1,000km into your sums and go from there.
