Two people taken to hospital, one in serious condition, after incident in West Auckland

A person has been take to hospital in a serious condition after a large ambulance call-out in Auckland.

Four ambulances and a rapid response unit were deployed to Swanson Road in Rānui just before midday.

Crews treated two patients - one was taken to Auckland Hospital in the serious condition, and the other to North Shore Hospital in a moderate condition.

Around 1.30pm, a number of sirens could be heard again in the area - lasting more than five minutes.

Police said on arrival officers located one person with non-life-threatening stab wounds and a 23-year-old woman was taken into custody over the incident.

Detective Inspector Callum McNeill said a detective and frontline staff were present with that victim at the centre when a separate incident unfolded outside.

"Our officers have become aware of a commotion outside, where a person had been running away after being stabbed in the head," McNeill said.

"Officers have moved outside to ascertain what was taking place, when they have seen the offender that had been chasing the victim."

Police said the offender was allegedly carrying a knife when he lunged at both officers, knocking one officer over and striking his body armour at the same time.

The offender then ran off and stabbed another member of the public in the shoulder, who was waiting for a bus at the time.

"The offender, a 29-year-old man, was swiftly taken into custody by other police colleagues nearby as they were already on scene due to the earlier incident," McNeill said.

McNeill added that a detective has suffered grazing injuries, and the other officer was not injured.

"The victims from the second event are in hospital with serious, but not life-threatening injuries," he said.

"This was an extremely concerning event, and I can reassure the wider community that our enquiries suggest that we are dealing with two separate and isolated incidents."

'He got hurt'

Shaneel Ranjay, from The Fading Hub barber, said he went outside to see an injured man and another man running off being chased by police.

"He got hurt," he told RNZ.

Ranjay said he saw the man with a knife in his hand.

He said he later learnt there had been an earlier stabbing at the rear of the neighbouring medical centre, Local Doctors Rānui.

Ranjay said he was told the staff at the doctors' clinic were told to evacuate because of that stabbing out the back.

He said the clinic remained closed.

A nearby primary school, Rānui Primary, posted on its Facebook page at 2.20pm about the incident.

"There was an incident at Rānui Medical Centre today," the post said.

"It is SAFE now but the road has been blocked and there will be traffic."

It said staff from Rānui Action Project would be at the corner of the school to guide students.

"If you would like to pick your children up please ring office and arrange for them to stay in the office until you come."
