A woman with stab wounds ran onto the road carrying a baby and screaming for help this afternoon, a witness has described.
Streets surrounding Willis Rd, Papakura are closed after a stabbing there about 12.25pm.
Daljinder Pangly told the Herald he was outside a nearby dairy when he saw an Asian woman in her 30s running towards him screaming for help and carrying a baby.
"She just ran out and was asking for help and I was outside the shop and I just ran to her and got the baby from her arms.
"She was very badly injured but the baby was fine."
He said the woman has stab wounds on her face, head, hands and back, but the baby was uninjured.
"She was kind of unconscious but she was responding until the ambulance arrived, so we just kept talking to her."
Pangly said other bystanders also rushed to the woman and used nappies from the dairy to try and stem the bleeding.
"I held the baby from her first, then someone else took the baby form me and I was helping he lady. Two or three ladies came and were helping, too."
In a statement, police said the 31-year-old woman was taken to Middlemore Hospital in a critical condition. Her condition was later downgraded to serious and her injuries are not believe to be life-threatening.
A 16-year-old boy was also taken to hospital with moderate injuries.
The scene was cordoned off for a time and motorists were asked to avoid Willis and Kelvin Rds and Sheehan Ave.
There was no risk to the public, the statement said.
A man known to the victim has been charged with assault.
