A 57-year-old man has died after a stabbing on Taumatamakuku Cres near Moerewa, in the Far North, last night.
When police were called to the scene about 8.45pm they found a man had been critically injured. He died shortly afterwards.
Detective Senior Sergeant Rhys Johnston, who is heading the investigation, said a 47-year-old woman who was still at the address had been taken into police custody.
Police were not seeking anyone else and there was no danger to the public. He would not say what the relationship between the two was.
The deceased's name would be released once all next of kin had been notified.
