This calculator estimates the road user charges (RUC) refund you can claim from NZTA Waka Kotahi for distance your vehicle covered off public roads, such as a farm, private land, a private road or driveway, or genuine off-road and forestry use. Because RUC only funds the public road network, kilometres travelled off public roads are not liable for the charge, and NZTA refunds the RUC already paid on that distance once you can show accurate records. You enter the off-road kilometres you want to claim, note what the distance relates to for your own records, and choose your RUC rate from the $76 per 1,000 km light diesel and EV preset, the $38 plug-in hybrid preset, or a custom rate, plus any NZTA processing fee if you know it. The calculator returns the RUC rate used, your estimated refund after any fee, and the refund before the fee, alongside a breakdown of the distance, rate, 1,000 km blocks and fee, plus a table comparing refunds at 1,000, 2,000, 3,000, 5,000 and 10,000 off-road kilometres. Use it to gauge whether a claim is worth submitting and check the numbers before you apply. You will still need a logbook or similar evidence of the off-road distance, and claims are generally subject to a minimum amount and a two-year time limit, so treat these figures as indicative only, pending NZTA's verification.

Summary:Enter your off-road distance above.
Honesty note: RUC refunds are claimed from NZTA Waka Kotahi and conditions apply. You must keep records, such as a logbook of off-road distance, and be able to verify them if asked. There is generally a minimum claimable distance and a time limit (claims must usually be made within two years of paying for the RUC licence). NZTA may deduct any applicable processing fee from your refund, and the amount paid depends on the current rules and your verified records. This is an estimate, not advice. See the NZTA RUC refund information before you apply.
What Is a RUC Off-Road Refund?
Road user charges (RUC) pay for New Zealand's public road network, so you only need to pay them for distance driven on public roads. If your RUC vehicle (a light diesel, electric vehicle, plug-in hybrid, or heavy vehicle) travels off public roads, that distance is not subject to RUC. You can apply to NZTA Waka Kotahi for a refund of the RUC you paid on that off-road distance. This commonly applies to farmers, foresters, and contractors whose vehicles spend time on paddocks, private land, private roads, or off-road, but anyone who can show genuine off-road travel may be able to claim.
How the Refund Is Calculated
The calculation is straightforward: divide your off-road distance by 1,000 and multiply by the RUC rate you paid. NZTA may then deduct an applicable processing fee.
Refund = (off-road km / 1,000) x RUC rate, less any NZTA fee
Worked Example
Suppose a farmer paid RUC at the standard light diesel rate of $76 per 1,000 km and recorded 3,000 km of genuine off-road travel on the farm over the period, with no processing fee entered. The refund works out as:
Off-road distance: 3,000 km
RUC rate: $76.00 per 1,000 km
Blocks: 3,000 / 1,000 = 3.00
Refund before fee: 3.00 x $76.00 = $228.00
Processing fee deducted: $0.00
Estimated refund: $228.00
These are the calculator's default figures. Change the off-road distance, the RUC rate, or the fee to match your own situation.
Current RUC Rates Used
Vehicle Type
RUC Rate (per 1,000 km)
Light diesel (under 3,500 kg)
$76.00
Battery electric vehicle (BEV)
$76.00
Plug-in hybrid, petrol (PHEV)
$38.00
Heavy vehicles (over 3,500 kg)
Variable by weight and axles
All rates are GST-inclusive and are bought in 1,000 km blocks. If you paid a heavy vehicle rate or a rate that differs from the presets, choose the custom option and enter the exact rate from your RUC licence so the refund matches what you actually paid.
How to Apply for a RUC Refund
Keep accurate records of off-road distance, ideally a logbook noting dates, locations, and kilometres
Work out the off-road distance you are claiming for each affected RUC licence
Complete the NZTA RUC refund form (available at nzta.govt.nz) for off-road or private-road travel
Submit your records and any supporting evidence with the claim
NZTA assesses the claim, deducts any applicable fee, and pays the refund
Minimum Claims and Time Limits
There is generally a minimum claimable distance, so very small claims may not be worth processing once any fee is taken into account. Claims must usually be made within two years of the date you paid for the relevant RUC licence, so it pays to claim regularly rather than letting eligible distance build up beyond the limit. Keep your logbook, invoices, and odometer notes in case NZTA asks to verify the off-road distance before paying.
