There are controls on the weight and axle loads of vehicles. This is to ensure safety is maintained through proper use of New Zealand’s road network.
If your vehicle exceeds the axle mass limits set out in the rule, you need to apply for a specialist vehicle permit. Permits are only able to be issued for route(s) that are suitable and safe for your vehicle and load.
To be eligible to apply for a specialist vehicle permit your vehicle must meet the following criteria:
Has no more than two rear axles, and four axles in total
Is a single unit (ie no heavy trailer)
The total mass does not exceed the total mass limits(external link) noted in the rule.
You can apply for a specialist vehicle permit by submitting an application to the road controlling authority of the road network you want to use, or through the online permit portal. You will also need to apply for a specialist vehicle road user charges (RUC) licence (see below for more information).
Permits are issued at the discretion of road controlling authorities.
Download the application form for a specialist vehicle permit or find it on the heavy vehicle permit portal. Please note that applications to Waka Kotahi NZ Transport Agency must be made through the permit portal.
Specialist vehicles operating at higher axle mass limits under permit are required to carry RUC licences covering the extra weight allowed (and reflecting impact to the road network). This ensures there is a level playing field for everyone in terms of weight limits and paying a fair contribution to the cost of maintaining New Zealand’s road network.
The rates are available on the specialist vehicle RUC application form.

A public transport service bus is a passenger service vehicle operating in a public transport service that is identified in or under a regional public transport plan as defined in the Land Transport Management Act 2003.
2-axle public transport services buses do not require permits for axle weights up to 9000 kg.
Other public transport service buses, and 2-axle buses over 9000kg axle weights, should use increased axle mass limits under permit.
