A fatal crash involving a truck and a pedestrian between Paraparaumu and Paekakariki caused delays for motorists heading south to Wellington City this morning.
Inspector Chris Tate said the incident happened about 3am, 500 metres north of the rail crossing entrance to Queen Elizabeth Park in the southbound lanes.
Police have named the victim as 46-year-old Rodney Thompson, who lived in the area.
Early indications suggested Thompson had been attempting to hitchhike in dark clothing at the time he was struck, a police statement said.
"Police understand that several motorists saw the man on the side of road and one may have had a near miss but did not contact police."
The truck driver was shaken by the incident and was taking time at home.
Tate said both lanes of the highway were cleared by 7am.
A fire truck attended to clean up the scene before the highway was reopened.
The police serious crash unit conducted an investigation from 3-7am at the scene.
Margaret Lewis from Paraparaumu Beach works at Wellington Airport and was on her way to work about 4am when she was stopped at a roadblock.
"I was turned round by police. There were two trucks in front of me but they could not be turned round because of the dividing wall on the highway."
