Do I need to use a logbook when driver guiding?

Yes, if you are a driver guide you need to comply with the Work Time and Logbook Rules. They set out how the limits to the work time hours for a driver of a vehicle that requires a Class 2, 3, 4, or 5 licence, or is used in a transport service (other than a rental service), or carries goods for hire or reward, are to be administered.

Please read the factsheet of NZ Transport Agency. and the Work Time & Logbook requirements.
