Land Transport (Road User) Rule 2004, rule 11.1
If you ride a skateboard or a scooter (the small-wheeled, unpowered type of scooter) or use in-line skates, you have to follow these rules:
if you’re riding on the road, you have to keep as close as possible to the edge of the road
on the footpath, you must be careful and considerate and not be a hazard to others. You have to give way to pedestrians and people on mobility scooters.
Unlike cyclists, you don’t have to wear a helmet or use lights at night if you’re riding a skateboard or scooter.
