A mum with children in her car was left bleeding after plunging onto a soccer field following a crash on Auckland’s North Shore.

The incident happened at 8.45am today, a resident who witnessed the aftermath said.

Emergency services were seen at Ashley Reserve in Long Bay where a car had smashed into the fence.

Three people were taken to hospital for treatment, St John Ambulance confirmed.

A car smashed through a fence and onto a soccer field following a crash in Long Bay, Auckland this morning.

Resident Mark Hughes, who was walking his dog at the time, told the Herald he saw at least three police cars, half a dozen officers, two ambulances and a fire truck at the playing field.

“A car had dropped about five metres down the bank after coming off the road on to the soccer field.

“A neighbour who was also there had assisted the occupants of the car, a mother with her little kids.

“She told him, as she was driving up Ashley Ave, another car was coming out of Cavali Rd and had collided with hers.

 “And her car swerved off-road. She had a bloody nose, and the kids were fine. All airbags had been deployed.”

Hughes said the other car was being towed away.

“It was a small car, driven by a student.

 “Police have been taking photos and trying to cut the fence to remove the car.”

St John Ambulance spokesperson said three people had been transported to North Shore Hospital following the crash.

Two people suffered moderate injuries and a third had a minor injury.

The spokesperson said three vehicles were sent to the scene - one rapid response unit and two ambulances.

A police spokesperson said they were notified of a crash involving two vehicles around the intersection of Ashley Ave and Cavalli Rd, Long Bay, around 8.31am.

No serious injuries had been reported and there appeared to be no blockages, they said.
