Police Commissioner Peter Marshall spent last night on patrol in inner-city Auckland and says his staff are worried about the abuse of alcohol.
Mr Marshall joined Detective Sergeant Iain Chapman and two other Auckland Central police for the evening shift, which involved a walk around the Viaduct Harbour and downtown Auckland.
Mr Marshall said the inner-city area was a problem spot for staff at weekends.
"It's fair to say that there's real concern by police officers in terms of the alcohol situation around K' Rd and Queen St. I intend to see first-hand what the situation is like."
Residents near and on Queen St have complained of fighting and drunken and reckless behaviour by revellers in the early hours.
