Are you having work completed on your vehicle?

The heavy vehicle specialist certifiers (HVSC) document below contains a list of heavy vehicle specialist certifiers in New Zealand and this list will be updated regularly.

If you wish to make modifications to your bus, truck, trailer or other heavy vehicle that change part or all of its structure or layout, you need to use a heavy vehicle specialist certifier to oversee your work.

For more about this, see our page about modifying heavy vehicles.

If you're applying to become a HVS certifier, read our guide to becoming a heavy vehicle specialist certifier.
