Two cherry orchard workers were killed and two others critically injured when the car in which they were returning home after work collided with a courier van.
The sedan carrying two men and three women - understood to be Chinese and Taiwanese nationals - crashed on State Highway 6 near Cromwell about 5.45pm on Thursday.
Two other people were killed in separate South Island crashes yesterday. A 57-year-old woman died after a car struck a power pole in Southland and a truck driver died when his logging truck rolled down a bank in North Canterbury.
