A man who died at Matatoki Quarry today is believed to have been hit by a truck.
Emergency services were called to Matatoki Quarry Rd, near Kopu, just after 1pm.
The Westpac Rescue Helicopter spokesman said on arrival at the scene the crew doctor went to help ambulance paramedics and was told the man was dead.
Because the death occurred in a workplace, the matter was being dealt with by Work Safe New Zealand, police said.
Work Safe said an inspector was on the way to the scene but they had no further details.
