Police are appealing for witnesses after a man was found deceased on State Highway 1, 13km south of Waipu on Saturday.
Emergency services were called about 8.50am yesterday to the scene, between the Waipu Gorge Rd and SH12 turnoffs.
Detective Sergeant Dave Wilkinson said the Serious Crash Unit attended andindications suggest the man was likely struck by a vehicle.
Police are now appealing for anyone who may have witnessed an incident on this stretch of road to come forward.
"We are particularly interested in speaking with anyone who was in the area of Brynderwyn Summit and Artillery Rd, between 7pm and 10pm on Friday evening," Wilkinson said.
