What Kiwi EV owners are actually paying in RUCs now

The RUC-free ride for light EVs ended on 31 December 2025. Here is what owners are paying mid-2026 and whether an EV still makes financial sense against a petrol or hybrid alternative.

The exemption ran longer than most expected. Light EVs in New Zealand had been free of road user charges since 2009, a policy that survived three changes of government and outlasted the Clean Car Discount, which was scrapped in December 2023. When the current government confirmed the exemption would end on 31 December 2025, it gave buyers roughly eighteen months of notice. Now that date has passed, the real-world cost picture has shifted, and it is worth being honest about what that means.

From 1 January 2026, light EVs pay $76 per 1,000km in RUCs. That is the same rate applied to light diesel vehicles. Buy 1,000km of RUC licence and hand over $76. It does not sound dramatic until you run the annual numbers. At 14,000km, you are paying $1,064 a year. At 20,000km, a figure not unusual for someone commuting from Rolleston or Rangiora into Christchurch, it is $1,520. Those are real dollars leaving your account before you have paid a cent for electricity, insurance, or tyres.

What an EV still costs to run

Charging costs vary significantly depending on whether you are doing most of it at home on overnight rates or relying on public fast chargers. A rough home-charging figure for a Nissan Leaf 40kWh is around $4 to $6 per 100km at standard residential power rates, maybe less on a low night rate. Call it $700 to $850 a year for that 14,000km driver. Add the $1,064 in RUCs and you are at roughly $1,750 to $1,900 in fuel-equivalent running costs.

A comparable petrol car, say a 2018 Toyota Corolla hatch or a 2019 Honda Fit doing the same 14,000km at 6.5L/100km, costs around $2,275 to $2,730 a year in petrol at $2.50 to $3.00 per litre. The EV is still cheaper, but the gap has narrowed. A year ago that gap was wider by roughly $1,000, because EV owners were paying nothing in RUCs while petrol buyers were paying fuel excise embedded in every litre.

The hybrid comparison is where it gets closer still. A 2019 Toyota Aqua at 14,000km might use 3.8 to 4.2L/100km in mixed driving, which comes to around $1,330 to $1,760 in petrol annually, no RUCs required, no home charger installation cost, no concern about apartment charging logistics. The Aqua is also sitting at $13,000 to $17,000 in the current used market, well below a tidy Nissan Leaf 40kWh at $18,000 to $24,000 or a BYD Atto 3 pushing $28,000 to $34,000.

The purchase price still does a lot of work

The EV case has always depended on how long you keep the car. Running cost savings compound over time, but only if the purchase premium is not too large. With RUCs now in play, the annual saving over a petrol equivalent has dropped from roughly $1,800 to $2,500 a year down to something closer to $500 to $800 for a moderate-mileage driver. At that rate, recovering a $5,000 to $8,000 purchase premium takes seven to fifteen years. That is a long time in a car that may need a battery assessment or replacement somewhere in that window.

Leaf batteries have held up better than the early narrative suggested, but a high-mileage 2016 or 2017 Leaf with 24kWh pack and twelve bars showing should be bought cautiously. Real-world range on an older pack in a Canterbury winter, with the heater running, can be 120 to 140km. For urban use that is fine. For anything regional, you are planning around chargers.

The 40kWh Leaf from 2018 onwards is a more sensible used buy, and 62kWh examples from 2019 to 2020 are starting to appear in the $25,000 to $30,000 range. These are better propositions. Parts availability is reasonable through local specialists, and the mechanical simplicity of an EV drivetrain means servicing costs stay low, typically $150 to $250 a year for brake fluid, cabin filter, and a general check.

Does it still stack up?

For a high-mileage driver doing 20,000km or more a year in a house with off-peak power and a home charger already installed, the EV still wins on running costs even after RUCs. The sums still favour it, just less dramatically than they did twelve months ago.

For someone doing 10,000 to 12,000km annually, the financial case is now marginal at best. A well-chosen petrol hybrid, a 2020 Toyota Prius or a Note e-Power, matches or beats the EV on total annual cost once RUCs are included, costs less to buy, and involves zero infrastructure thinking.

The EV is not a bad choice in 2026. It is just no longer a straightforward one. The maths requires more work than the sales pitch suggests, and buyers owe it to themselves to do that work before signing anything.
