A young man has suffered critical injuries after being trapped inside the roll cage of his small dump truck at work near Riverhead, northwest of Auckland, this morning.
A St John spokeswoman said two ambulances, a rescue helicopter and Fire and Emergency Service crews attended.
"A male in his late 20s has been transported to Auckland Hospital in a critical condition," she said.
Waitemata Senior Sergeant Ian Byrne said emergency services were called to the area, near Helensville, about 9.30am.
