One person has died after the serious incident at a Hoani Street, Northcote address in Christchurch on 18 February.
Police were called to the property about 9.30pm after an altercation during which four people were injured, one of whom was in a critical condition.
“Sadly, that person has now died in hospital”, said Detective Inspector Nicola Reeves.
“Our thoughts are with their family, who are no doubt devastated. We will continue to provide them with support at this difficult time.
“Police can confirm that the individuals involved were associated with two separate gangs, however our investigation to date indicates this was not a gang-motivated attack. This appears to be an isolated incident between specific individuals.
“We want to be absolutely clear that any form of retaliation will not be tolerated.
“Anyone considering taking matters into their own hands should expect an immediate and firm response.
“We understand incidents like this can be unsettling to our community, and want to reassure you that there is no information to suggest any ongoing risk to the wider public.
“Our teams are maintaining a visible presence and continue to work closely with specialist units, intelligence staff, and community partners to ensure your safety.
“Further charges will now be considered against the three men who were arrested in relation to the incident.”
The three men, aged 19, 31 and 40, have been remanded in custody and are next due to appear in Christchurch District Court on 17 March.
