A person has died in hospital following an alleged home invasion in Christchurch last week.
Four people were injured in the incident on Hoani St in Northcote on February 18, including one who was left fighting for their life.
That person has since died, police said in a statement on Thursday evening.
“Our thoughts are with their family, who are no doubt devastated,” said detective inspector Nicola Reeves.
Three men aged 19, 31 and 40 were earlier charged with aggravated wounding and aggravated robbery.
Reeves said further charges were being considered following the person’s death.
Those involved were linked to two separate gangs, Reeves confirmed, however the incident was not suspected to be a gang-motivated attack.
“This appears to be an isolated incident between specific individuals.”
Retaliation would not be tolerated, Reeves added.
“Anyone considering taking matters into their own hands should expect an immediate and firm response.”
A local resident previously described how “all hell broke loose” after the altercation, which allegedly involved Mongrel Mob and Black Power members.
A gun was allegedly fired and a machete wielded during an ambush as one of the groups returned home, Stuff understands.
Reeves acknowledged the incident would have been distressing to the Northcote community, but said there was nothing 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.”
