Police are investigating a “violent” melee in South Auckland that spilled onto a street, leaving a person knocked unconscious after being struck in the head with a weapon. Emergency services were called to an Ōtāhuhu address around 10.52pm on Tuesday. Police said the parties involved are “all known to each other”. “A fight began after a disagreement at a Hauiti Rd address,” Detective Senior Sergeant Mike Hayward, of Counties Manukau West CIB, said. “This fighting spilled out onto the road, and two people were chased down the road. “One of the two alleged aggressors got into a vehicle and drove down Hauiti Rd. “A short time later, this vehicle collided into two parked vehicles on Hokonui Rd.” A section of Hokonui Rd in Ōtāhuhu was cordoned off on Tuesday night.
