Buy RUC
You buy RUC online through NZTA, or in person at an agent, and you are buying a block of distance in advance rather than settling a bill. The number that decides whether the purchase is right is your current odometer reading — get that wrong and you either throw away distance you paid for or leave a gap you will be invoiced for later.
Buying RUC takes a couple of minutes and almost all of the risk sits in one field: the odometer reading. Everything else — how many blocks, which channel, which card — is reversible or trivial. The reading is what defines where your new licence starts, and a wrong reading quietly costs you either money or legal cover.
Before you start, have these
You need the vehicle's plate number, its current odometer reading in kilometres, and a way to pay. If you are buying for a heavy vehicle you also need to know the RUC vehicle type and the weight you are licensing it at, because those determine the rate rather than being looked up for you.
Go and read the odometer. Not the reading you remember, not the one on the last licence — walk out and look at the dash. This sounds patronising until you meet someone who bought a licence starting 400 km behind where their vehicle actually was.
- Check where your current licence ends
Your last RUC licence has an end reading. That is the number the new licence should pick up from. Checking your RUC position tells you what NZTA currently has recorded against the vehicle.
- Read the odometer now
In kilometres, whole numbers, ignoring the trip meter. If the vehicle is already past the end reading of the last licence, note the difference — that distance has to be bought too.
- Decide how far ahead you are buying
RUC sells in blocks of 1,000 km. Buying more blocks at once means one transaction fee instead of several, but ties up money in distance you have not driven.
- Buy it and keep the confirmation
Save the receipt or licence document somewhere you can find it. It is your evidence of the start and end readings if a later assessment disagrees with you.
Where you can buy it
The main channel is NZTA's own online transaction service, reached from its road user charges section. NZTA also documents the full set of purchase options on its RUC licences page.
In person, RUC is sold at appointed agents. That network overlaps with — but is not identical to — the places that renew your rego, so the sensible move is to check the agent handles RUC before driving over. Vehicle licensing agents explains how that network is organised and where NZTA publishes its own list.
Some fuel companies, telematics providers and fleet services also sell RUC or manage it on your behalf, particularly for businesses running several diesel vehicles. The licence is still issued by NZTA underneath; you are paying someone to handle the admin and the reminders.
The mistakes that actually cost people money
Entering a reading below the true one. Your licence then starts behind the vehicle, so part of what you just bought covers distance you already drove. You lose the difference and you are still short at the other end.
Entering a reading above the true one. You have created a gap between where your last licence ended and where the new one starts. Distance driven in that gap is unpurchased, and NZTA can assess it whenever it surfaces.
Buying against the wrong vehicle. If you own more than one diesel, the plate number field is doing real work. RUC attaches to a vehicle, not to you, so buying 3,000 km against the ute does nothing for the van.
Assuming a reminder will come. RUC is not like a rego reminder tied to a fixed date. Whether you get a prompt depends on how you bought and what contact details NZTA holds. Treat the responsibility as yours.
There is no grace period built into the distance. The moment your odometer passes the end reading on your current licence, further distance is unpurchased. It does not stop the vehicle, it does not flag on the dashboard, and it accumulates silently until an inspection or a transaction exposes it.
Buying for a vehicle you just bought
RUC stays with the vehicle. If the previous owner left unused distance on the licence, you inherit the benefit of it — and if they left unpurchased distance, you can inherit that argument too, which is why checking the RUC position before you hand over money matters. The seller's word is not evidence.
Working out how much to buy
If you know roughly how far you drive in a year, the arithmetic is simple, but the rate you multiply by depends on your vehicle. RUC rates and cost explains how the rate is arrived at for light diesel, fully electric and plug-in hybrid vehicles, and for the weight-and-axle classifications that apply to heavy vehicles. NZTA also publishes an official calculator if you would rather have the sum done for you.
Once you understand the rate, the rest of the RUC system — refunds, assessments, what happens when you sell — is covered in our RUC overview.
