Stationary vehicle infringement notice?

As much as it sucks.....your vehicle has to be a TSL registered vehicle to stop in a loading zone. Unless you have the sticker in your windscreen, then your toast.

Win some lose some! If you are time rich and cash poor try writing a letter to see if they let you off. Otherwise the easiest and lowest cost option is to pay up and move on.

From the Road User Rule definitions -

goods vehicle means a motor vehicle that is—
(a) designed exclusively or principally for the carriage of goods; or
(b) used for the collection or delivery of goods in the course of trade

and also from the RUR -

6.16Parking on loading zone
(1) A driver or person in charge of a vehicle must not stop, stand, or park the vehicle on any part of a roadway reserved by a road controlling authority as a loading zone—
(a) if the vehicle does not belong to the class (if any) specified on the sign; or
(b) if the driver leaves the vehicle unattended for more than 5 minutes or any period longer than that specified on the sign; or
(c) if goods or passengers are not actually being loaded or unloaded from the vehicle.
(2) This clause applies only if the location of the loading zone is indicated by the road controlling authority by the installation of the appropriate parking signs and markings prescribed by Land Transport Rule 54002: Traffic Control Devices 2004.
(3) Nothing in subclause (1) permits a vehicle to be left unattended within a loading zone if the appropriate parking sign indicates that the vehicle must be attended at all times.

I'd write a letter and as long as it isn't shitty I would expect to get the ticket cancelled.
