Drivers' crash deaths 'a terrible coincidence'

Both drivers who died in a crash south of Oamaru on Monday worked for the same company in what the chief executive has called a "terrible coincidence".

A large truck and trailer collided with a car in Alma at 9am on Monday, leaving both drivers dead.

The truck was carrying coal for Hilton Haulage, but the company has confirmed the second driver was travelling privately on their rostered day off.

Chief executive Dylan Fitzgerald said it was a "terrible tragedy for the families involved and the Hilton Haulage team".

"We are all shocked by this terrible coincidence and our deepest sympathies go to both families during this time."

It was unable to comment on any possible causes of the accident, but would fully support the police in their investigations, he said.

An internal investigation would also be conducted.
