Five people have been arrested for what police say was the random killing of a Wanganui man two months ago.
Police raided four addresses at the same time on Tuesday morning in Wanganui and Patea.
Paul Kumeroa, 28, was walking home from a party at 9.30pm on 23 September when he was assaulted at Castlecliff - apparently for no reason. He died of head injuries in Wanganui Hospital.
Police earlier said his attackers were intoxicated and caused disturbances at parties across the city before and after the attack.
Two men, aged 22 and 17, and two women, aged 22 and 19, were arrested in the city and a man, 34, was arrested in Patea.
All are from Wanganui and all are jointly charged with murder.
The five appeared in court on Tuesday afternoon and were granted interim name suppression.
Police hope people who have been reluctant to speak up will do so now that murder charges have been laid.
Mr Kumeroa is survived by a partner of 11 years and a son, aged 18 months.
