A 44-year-old man was struck by a car and killed as he walked south along the Waikato Expressway.
Why he left his car in the southbound lane and proceeded to walk off in the distance remained unclear, Waikato road policing manager Senior Sergeant Pete van de Wetering said.
The man had stopped his vehicle just north of the Horotiu off-ramp about 7.30pm last night, he said, and was walking near the fog line when he was fatally struck.
One motorist approaching the man from behind had managed to swerve and avoid him, however a second vehicle didn't see him until it was too late.
"We don't know why the car had stopped, it may have run out of fuel or something, but he's left his car and he's walking on the expressway. Two vehicles have approached him from behind. The driver of the first vehicle has swerved to miss him after seeing him at the last minute.
