The person killed in yesterday's fiery truck crash on State Highway 1 was an employee of Winstone Aggregates.
On Friday morning both lanes of Auckland's SH1 on the Bombay Hills were closed after a truck travelling southbound reportedly rolled and caught fire near the Beaver Rd off-ramp.
A spokesperson from Fletcher Buildings said police told them yesterday that one of their Winstone Aggregates colleagues had died in the single-vehicle crash.
"The details are still being established and we are awaiting further information from police," they said.
They said their first priority was to support the driver's family.
"Our thoughts are also with the Winstone's team who have lost a colleague and friend," they said.
"This has shocked and saddened people across Fletcher Building and our deepest sympathies are with our colleague's family, friends and teammates for their loss."
A spokesperson from WorkSafe also confirmed they had been notified, and could provide more details next week.
Police said the circumstances of the crash were still under investigation, and they could not yet release the name of the person who died.
The highway was closed n Friday afternoon after the 11.40am crash.
Nearby residents described hearing a "huge explosion" and seeing a massive plume of smoke.
"And then explosion sounds twice again. It was so loud and there was smoke everywhere," a witness said.
Police said yesterday the person had died at the scene.
