Detective Kevin Kirkman, of Oamaru, confirmed the fatal crash occurred near Iona Home and the Galleon Family Complex.
"We would like to hear if anyone saw anything or recorded it, or has dashcam footage," Det Kirkman said.
It was believed a woman slipped on to the road before being hit by a vehicle.
