The Class 2 load pilot licence is the starter level for load piloting in NZ.
To first gain the licence, you need to download the Pilot Guide book from here to read and understand it: https://www.nzta.govt.nz/resources/load-pilot-driver-code/
Then book in for the class 2 pilot test here: https://nzta.aspeqexams.com/home
Just select exam schedule and then the specialisation is “Heavy Haulage”. You need to register and then you can book in test at a place close to you. The cost is $138 incl GST.
Aspeq have provided a user guide about how to register and book in for the test. View/Download User Guide
A video guide has also been produced that provides guidance about how the test will be conducted. View Video Guide
Note that while the test is "open book" you cannot take in the NZTA Course Guide Book - however one will be provided at the test venue.
There is an option to sit and pass NZQA Unit Standard 1768 for class 2 piloting, but this is usually once you have gained some competency with load piloting.
