Workers shocked at death of colleague after stabbing, car attack in Mangere Bridge

Workers at an Auckland packaging company are mourning the death of a colleague after a stabbing and car attack at the company's property on Thursday in Mangere Bridge.

A homicide investigation has been opened into the incident, which happened at paper company Oji Fibre Solutions on Mahunga Dr on Thursday afternoon after one woman was stabbed and two others were run down.

The 32-year-old woman who died had been hit by the car.

Witnesses told Newshub all the victims worked at the factory, but they believe only one of them was targeted by the offender.

Witness Darrell Patton said the aftermath was chaos.

"We came out and had a look and it was just a bit crazy," he said.

"They cordoned off the road and more police cars and fire engines and all that came."

The woman who was stabbed and the other man run down have now been discharged from hospital.

A 46-year-old man has been charged with attemped murder and appeared at Manukau District Court on Friday.

The name of the accused will remain a secret for now but only because his lawyer appealed the judge's decision to make it public.

He will reappear at the High Court in Auckland next month and police won't rule out laying further charges.

In a statement, Oji Fibre Solutions says it's shocked and wants to make sure it looks after its people and does the best it can to assist police.

It closed its factory on Friday as it's currently being treated as a crime scene.
