A Picton man has chest injuries after a logging chain snapped and smashed through the cab of a digger he was driving.
The forestry worker, 22, was working with a team in the North Bank area near Renwick when the accident happened about noon, Nelson Marlborough rescue helicopter pilot Tim Douglas-Clifford said.
The man was using a digger when the chain snapped and hit him in the chest, Douglas-Clifford said.
The helicopter landed on a nearby logging track in muddy, wet conditions.
An intensive care paramedic treated the man at the scene. It took about 40 minutes for him to be stabilised so he could be transported, Douglas-Clifford said.
He was flown to the emergency department at Nelson Hospital with chest injuries and was in a stable condition.
A WorkSafe New Zealand spokesman said WorkSafe was investigating the accident.
