Heavy Vehicle RUC Calculator NZ
This calculator works out how much road user charges (RUC) will cost each year for a truck or heavy vehicle in New Zealand. RUC funds road maintenance for vehicles that do not pay fuel excise, and for heavy vehicles the rate depends on your RUC vehicle type, a number NZTA sets from your vehicle's weight and axle configuration. Choose from common preset types (Type 1, 2, 6, 14 and 19) with their current rate per 1,000 km, or select "Other" and enter your own rate straight from your RUC licence if your type is not listed. Then enter your estimated annual driving distance, how you buy RUC (online or through an agent, each with a different admin fee), and the block size you purchase each time. The calculator returns your RUC rate, total annual RUC cost including admin fees, your effective cost per kilometre, and total admin fees for the year, plus a detailed cost breakdown, a table comparing costs across different annual distances, and a plain-language summary. Use it to budget commercial vehicle running costs, see how larger purchase blocks reduce admin fees, or check what a heavier RUC type would cost you. Because NZTA assigns many more RUC types than the presets shown here, always confirm your exact type and rate from your licence or the official NZTA rate table. Figures are indicative estimates only.

How Heavy Vehicle RUC Works in New Zealand
Road user charges (RUC) are how New Zealand collects road maintenance funding from vehicles that do not pay (or pay less) fuel excise duty, including all diesel vehicles. Petrol vehicles pay through fuel excise of about 70 cents per litre included in the pump price, so they do not buy RUC. For heavy vehicles, the amount you pay is not a single flat rate. Instead it is set by your RUC vehicle type, a number that combines your vehicle's gross weight and its axle configuration. Heavier vehicles and configurations that load the road more heavily are assigned a higher rate per 1,000 km.
Common Heavy RUC Vehicle Types
The presets in this calculator are a small selection of verified NZTA types to illustrate the range. There are many more types than these. Always confirm your own type and rate from your RUC licence or the official NZTA table.
| RUC Type | Description | Rate (per 1,000 km, incl GST) |
|---|---|---|
| Type 1 | Light vehicle (up to 3,500 kg) | $76.00 |
| Type 2 | 6,001-9,000 kg | $126.00 |
| Type 6 | 12,001-18,000 kg | $356.00 |
| Type 14 | Heavier configuration | $435.00 |
| Type 19 | Heavier configuration | $389.00 |
| Other types | Many more by weight and axles | See NZTA table / your licence |
If your type is not listed, choose "Other - enter my rate" in the calculator and type the exact rate from your RUC licence. This keeps your annual estimate accurate for any RUC vehicle type NZTA has assigned.
Where to Find Your RUC Type and Rate
Your RUC vehicle type number is printed on your current RUC licence (the label you display). You can also look it up in the full RUC rates table on the NZTA Waka Kotahi website, which lists every type with its weight band, axle arrangement, and current rate. If you operate a mixed fleet, each vehicle can sit in a different RUC type, so check each licence individually.
Admin Fees and Block Sizes
An administration fee applies every time you buy a RUC licence, no matter how many kilometres are on that purchase. The fee is $12.44 (including GST) online or via the NZTA app, and $13.71 at an agent counter. Because the fee is per transaction, larger blocks lower your effective cost per kilometre. On a high-rate heavy vehicle the distance charge dominates, so admin fees are a small part of the total, but spreading them across larger blocks still trims the cost. RUC is sold in 1,000 km blocks with no maximum.
Worked Example
Take a Type 6 truck (12,001-18,000 kg) at $356.00 per 1,000 km, driving 50,000 km a year, buying RUC online in 10,000 km blocks. The distance charge is 50 blocks x $356.00 = $17,800.00. At 10,000 km per purchase that is 5 transactions, so admin fees are 5 x $12.44 = $62.20. The total annual RUC is $17,862.20, which works out to about 35.72 cents per kilometre once admin is included. These are the calculator's default figures above.
Heavy Electric Vehicles
Heavy electric vehicles over 3,500 kg are not required to pay RUC yet. They become liable from 1 July 2027, after which they will pay under the RUC vehicle type that matches their weight and axle configuration, the same as heavy diesel trucks do today. Heavy diesel vehicles already pay RUC now.
Future Changes
The government has announced plans to move all vehicles to RUC and remove petrol excise duty over time, with the system also opening up to private collection under amendments to the Road User Charges Act 2012. The details, including pricing and timing, have not been finalised (announced around 2027). Until then, the current system of pre-purchasing distance in 1,000 km blocks by RUC vehicle type continues to apply.

This calculator provides indicative estimates only. Heavy vehicle RUC is set by your specific RUC vehicle type (weight plus axle configuration), and there are many more types than the presets shown here. Confirm the exact type and rate from your RUC licence or the official NZTA rate table, and use the custom rate option for any type not listed. Check nzta.govt.nz for current rates and to purchase RUC.
