A six-year-old girl suffered two broken legs when she was crushed between a vehicle and a fencepost in a farm accident near Ashburton.
Rescuers have praised the quick actions of the girl's mother for preventing the young girl from suffering worse injuries.
The girl suffered multiple fractures to both legs after being pinned between a vehicle and a fence post on the Maronan property about 2pm on Sunday, a Westpac Rescue Helicopter spokesman said.
"She was standing beside the gate as her mum was driving through it. It was wet under the tyres and the heavy trailer on the back of the four-wheel-drive pushed it over to the side."
The young girl was in the wrong place, at the wrong time, as the vehicle started sliding.
