Heavy Vehicle Certification Categories
There are different certification categories and each individual certifying engineer must pass examination in a category or categories before being authorised to certify heavy vehicles for that particular type of work. See below for a list of heavy vehicle certification categories and the work involved in each.
When you know the certification category related to the component and/or task you need, you can visit the Waka Kotahi (NZTA) website here for a comprehensive list of Heavy Vehicle Specialist Certifiers (HVSC) authorised to conduct this work.
