Guidance for operators

The full HPMV network map shows the routes that are suitable for high productivity motor vehicles (HPMVs) carrying the maximum loads available under a permit.

The map is intended to give operators guidance on where bridges can safely support full HPMV mass limits. It does not mean that HPMVs cannot travel under a permit on roads that are not on the map, but the permit may specify lower mass limits for those roads.

The full HPMV network map differs from the 50MAX network map. If you intend to operate on both networks, you need to familiarise yourself with the differences between the two networks and understand how they apply to your permit. If you are in doubt, please refer to volume 1 of the VDAM permitting manual (external link)  for more information, or contact your regional permit issuing officer (external link) .

Users of this map

The road transport industry, permitting staff at the Transport Agency and their consultants, road controlling authorities, and the NZ Police Commercial Vehicle Safety Team.

Changes to the map

As more roads and bridges are being strengthened, the full HPMV network map will be updated to include more routes. We suggest you come back here from time to time.

Frequently asked questions

What is full HPMV?

Full HPMV refers to the HPMV mass limits in the VDAM Rule schedule 3, parts 3 and 4. It applies to the maximum axle mass limits as well as the maximum total mass limits that are available under an HPMV permit. 

If my route is not on the map, can I still get a permit?

Yes, you can still apply for an HPMV permit if your route is not (or only partially) on the full HPMV network map. But the axle mass and total mass limits on the permit are likely to be less than the full HPMV limits. 

What vehicle designs suit full HPMV?

In general, you will need a truck and trailer or B-train combination with at least 8 axles that is capable of carrying full HPMV loads within its design certifications (such as GVM and GCM). Your vehicle must also have the axle types, tyres and axle spacings set out in schedule 3, parts 3 and 4 of the VDAM Rule.

Will my 50MAX truck be suitable for full HPMV?

Many 50MAX vehicle designs are capable of taking higher loads. If you hold a permit for 50MAX, then it is likely your vehicle will be suitable for full HPMV. You will need to apply for a new permit. 

Will I need a vehicle attributes check?

Yes.  Before you apply for an HPMV permit, you will need to obtain a completed and signed HPMV attributes check sheet from an approved heavy vehicle specialist certifier.

When completing the HPMV attributes check sheet, certifiers assess whether a vehicle is technically capable of carrying a heavier load within its certifications. They check that a vehicle meets a number of requirements including gross vehicle mass.

If you cannot locate a certifier near you, please check with your regional permit issuing officer (external link)

What if my truck configuration doesn’t meet the requirements for full HPMV?

You may still be eligible for an HPMV permit, but with lower mass limits than full HPMV. For details see Chapter D2: Vehicle requirements for HPMV higher mass permits in volume 1 of the VDAM permitting manual (external link) .

You can also apply for a feasibility assessment on the Heavy Vehicle Permit Portal (external link) by selecting the Feasibility option on the HPMV permit application form. We will undertake a feasibility study of your vehicle combination, your load and the route you want to travel on and let you know whether you can get a permit. Please note that a feasibility application may take more time to process.
