Auckland Police are urging people to come forward with information about a man who was "acting aggressively" towards members of the public.
Police said he was confronting people around Britomart in Auckland City on Saturday night and into the early hours of Sunday.
"In one incident a group was confronted by the man in the vicinity of Tyler Street and Queen Street around 2:30am," a police spokesperson said.
"The man allegedly pulled a tyre iron from his trousers and started swinging it at the group, hitting at least one person."
The man also punched another person, police said, causing them to fall to the ground.
Anyone involved in one of these incidents or who's had similar experiences is encouraged to come forward and speak with police.
"This behaviour will not be tolerated by Police and we would like to hold this person accountable for their actions."
Information can be given by contacting the Auckland City Crime Squad on 09 302 6557 and quoting file number 220918/8757.
