Northern Irishman John-Paul Nelson died after crashing head-on into a Timaru-based freight truck carrying offal near Hinds on Monday night.
The 30-year-old's ute flipped onto its roof and the Hilton Haulage truck jack-knifed in the smash on State Highway 1.
Sergeant Bryan Ennis said the agricultural worker, who had been in New Zealand since November 2013 and lived in Mid-Canterbury, crossed the centre line and ploughed into the southbound truck and trailer unit.
Offal was strewn across the road, which the freight company cleared in the hours after the crash.
Police were yet to determine the cause of the crash, Ennis said.
The Hilton Haulage truck driver, a man in his 30s, suffered bruised knees in the accident.
Four fire crews from Ashburton and Hinds attended the accident.
Meanwhile, police yesterday named the dairy farmer killed in a crash north of Winton in Southland early on Monday.
Stefan Zeestraten, 24, of Centre Bush, died when his four-wheel-drive vehicle left the road and slammed into a power pole.
Western Southland area response manager Senior Sergeant Cynthia Fairley said emergency services responded to the crash in Limehills-Browns Rd about 3am.
"It appears the vehicle had crossed on to the wrong side of the road and impacted on a concrete power pole before coming to rest in the ditch," Fairley said.
The power pole was dislodged at the base but remained upright because of the wires.
Zeestraten, an Otapiri dairy farmer, was trapped in the vehicle but was found dead, she said.
The serious crash investigator had forensically mapped the scene and the investigation was continuing, Fairley said. Fairfax NZ
