Several police investigations are underway in Auckland after separate weekend incidents that claimed the life of a man and put two others in hospital.
One man died after a fight in west Auckland, another was stabbed in the central city and a third man was found unconscious in Pukekohe.
Police are treating the death of Connor Morris in Massey as a homicide after a fight between two groups on Don Buck Road last night.
The 26-year-old died on the way to hospital; a post mortem has confirmed he had a head injury.
Police believe a weapon was used but say they're not sure what that was. They say up to 30 people are witnesses to the fight.
Police say the attack was random and there's nothing to suggest the fight was the result of gang tensions.
Police say they have arrested a man they were seeking in relation to a stabbing in central Auckland.
Officers were called to the old Auckland Railway Station on Te Taou Crescent just before 3pm on Saturday, where a man had been stabbed in the rib area. He was taken to hospital in a serious condition.
Police say Bensemann Vakauta, a 22-year-old they described as extremely violent in warnings to the public not to approach him, has been located and is now in custody.
Early Saturday morning, a man was found unconscious on the side of a road in Pukekohe.
The 24-year-old is critically ill and the police are trying to piece together what happened to him.
