A female pedestrian died when she was hit by a truck at the intersection of London St and SH3 in Wanganui last night.
Firefighters who attended the scene said it was unclear what she was doing on the road, as the nearby walkway was fenced off.
Emergency services were called to the scene at 11.10pm.
Witness Christopher Cape was getting petrol at the Gull Service Station near the intersection when he heard the truck driving up the bypass and coming to a stop before it reached the merge section.
"I saw it drive reasonably slowly up and then it stopped, and I thought, 'good grief, that's odd'," Mr Cape said.
