Northland police are appealing for witnesses to a second altercation that occurred before a man was allegedly killed in the Bay of Islands.
Police said 22-year-old Okaihau man Bram Willems died after being stabbed last Thursday night in Ōpua and a 14-year-old boy has been charged with his murder.
Earlier this week police appealed for a woman who had witnessed an altercation in Kawakawa's main street earlier that night to come forward.
Police said the woman had now contacted police, but they were now aware of another alleged altercation also in Kawakawa a short time after the main street fight.
Detective Senior Sergeant Geoff McCarthy said officers conducting a homicide investigation over the death of Mr Willems are appealing for witnesses to the second altercation before his death.
