Police were liaising with the crash victim's family last night, which included help from Victim Support.
The man's name wouldn't be released until all of his family were notified of the accident.
Hawke's Bay Road Policing Sergeant Kevin Stewart said the crash happened at a time when there was high traffic on Meeanee Rd. "It was just before rush hour. There were a lot of vehicles on the road. Meeanee Rd is a main thoroughfare which a lot of people use to get to and from work."
It was a "sizeable operation" to close the road in the wake of the crash, involving traffic police and civilian contractors.
Central Fire Communications shift manager Jan Wills said that two fire crews from Napier had attended the crash scene.
Meeanee Rd was closed from Willowbank Ave to Napier St, while Tannery Rd was closed where it meets Burness Rd. The road closure lasted about three hours. Mr Stewart said the truck driver had been with Emmerson Transport for some time and was considered experienced.
Yesterday's crash pushed the 2014 road toll for Gisborne and Hawke's Bay to 15.
There have been 248 fatal crashes on the country's roads this year.
