In this section you can find all the relevant information about high-productivity motor vehicles (HPMVs), including how to apply for a permit, commonly asked questions, and maps that show which routes have been approved so far.
If you want to carry divisible loads, such as logs, milk powder or freight, more productively, you may be able to operate on an HPMV permit.

In September 2011 and May 2014, Waka Kotahi NZ Transport Agency and the Ministry of Transport completed a monitoring, evaluation and review of the implementation of the Vehicle Dimensions and Mass Rule.
The review considered the economic impact, impact on infrastructure, impact on safety, operator experience, RCA feedback, Commercial Vehicle Investigation Unit (Police) feedback, and ongoing reporting frameworks.

One of the key changes in the amended rule is to allow divisible loads to go over 44 tonnes and have longer than current ‘as-of-right’ lengths, but only with a permit and only on roads approved as suitable for such trucks. The as-of-right weight limit for trucks is unchanged at 44 tonnes – the total length limit for most combinations is still 20 metres.
There is also a change in the as-of-right lengths for some trucks that have been operating under an overlength permit, such as logging trucks. Those trucks can now be 22 metres as of right.
The permit systems for indivisible overweight and overdimension loads are unchanged

HPMV permits will be approved for suitable vehicles carrying divisible loads of economic importance. Permitted vehicles must also be able to travel on routes that are suitable for the vehicle and load being approved.
As well as ensuring that your vehicle and its load comply with the dimensions requirements in the Land Transport Rule: Vehicle Dimensions and Mass Rule 2016, you must also check the route you intend to operate on to ensure compliance with section 2.1 (1) of the rule, to make sure your vehicle and its load is manoeuvrable, fits safely on the road and interacts safely with other road users. Failure to meet this requirement can result in an infringement note being issued.
