Police are calling on the public to help identify people involved in a mass brawl on Auckland's Karangahape Road last month

The fight, which took place early on the 28th, involved about 50 people.

Police are investigating three serious assaults, with one person already arrested.

Detective Senior Sergeant Mark Greaves says they want help identifying two people, in newly released images.

One male was seen wearing black pants, a blue and black hunting and fishing jacket, and a black cap with white writing.

The second was wearing a white shirt and a beige hat.
