As a pre-requisite for any endorsement you must already hold a current full Class 1 driver's license. The operator must have held the appropriate full class of license for at least two years in the Gross Vehicle Mass (GVM) for which the endorsement is required.
Once you’ve completed this course, you can take your endorsement certificate to a licencing agency like AA, VTNZ or VINZ and complete the paperwork to get it added to your driver’s licence.
