An incident that left four people injured, one critically, in Christchurch is believed to involve rival gangs Black Power and Mongrel Mob.
Emergency services were called to an address, understood to be a Kāinga Ora home, on Hoani St in Northcote about 9.30pm on Wednesday.
One person has life-threatening injuries, and another was seriously hurt.
The two others had minor or moderate injuries, police said.
RNZ understands the incident is believed to involve members of rival gangs Black Power and Mongrel Mob.
An RNZ reporter at the scene last night was told by police that there had been reports of shots being fired.
"The community can be assured that police are working at speed to identify and locate those involved.
"Police believe the parties involved are known to each other and the risk to wider public is minimal."
One resident said they heard yelling before police arrived last night.
Another said he woke up to see police cars lighting up the street and officers with guns.
Armed police were still stationed at cordons on Hoani St this morning with a manhunt underway.
Hill said there would be more officers in the Northcote area today "as we work to resolve this incident as swiftly as possible".
A scene examination is underway at the property.
Police are appealing to anyone in the area who may have witnessed anything last night to contact them. They can be contacted on 105 using file number 260218/3391.
