More charges have been laid after pedestrians were allegedly run down by a vehicle outside Auckland University's engineering school

The 20-year-old driver is due to make his first appearance in the Auckland District Court this morning.

Court documents show he is facing a charge of possessing a drug utensil, possessing four canisters of nitrous oxide, two charges of carelessly operating a vehicle, and a further three charges of operating a vehicle carelessly and causing injuries.

Police initially charged him with the three counts of careless driving causing injury when he was arrested on Tuesday.

He was bailed to his home address.
