A woman ran over her partner several times with a car in front of stunned onlookers at Hamilton shops before fleeing from police and crashing into the Waikato River today.
The man suffered serious injuries when he was hit by the car, Acting Detective Inspector Ross McKay said.
The incident began just before midday.
"At this time a male pedestrian has been run over by a car driven by his 44-year-old female partner at the Ohaupo Rd shops by the intersection with Normandy Ave,'' he said.
"The driver was described by witnesses as driving over the victim a number of times before fleeing, leaving the man with serious injuries.''
