The Manufacturer Certification process involves an Inspecting Organisation (IO) and a Vehicle Inspector (VI) who will both be covered by Notices of Appointment and will have responsibilities directly to the NZTA. Each of these roles is vital and interdependent. A local manufacturing certifier IO cannot certify a heavy vehicle while a local manufacturing certifier VI can only certify a heavy vehicle within the requirements of the VIRM and Memos if s/he is in the employ of a manufacturing certifier IO and the NZTA has a record of this employment. See complete memo HV_Info_Bulletin_78.pdf

The advantage for the certifiers is that they will be able to carry out a greater range of work without requiring the direct input of a HV Specialist Certifier. It is envisioned that the range of work which will be able to be done by Manufacturing Certifiers under this process without direct input of a HV Specialist Certifier will increase over time.

The TTMF has developed and now manages the assessment course on behalf of NZTA. Completing these modules successfully is a prerequisite to the new IOVI regime Those companies who complete the course can apply for approval with NZTA to become an IOVI.
