The driver of a campervan mistook a "notorious" King Country intersection for a roundabout and was hit by a truck, killing his wife, says a witness.
The Canadian couple and their adult daughter - on a month-long holiday - had just spent four hours on a caving adventure and were at the intersection of Waitomo Caves Rd and State Highway 3 on their way to Tongariro when the crash happened just before 2pm yesterday.
The 59-year-old mother in the front passenger seat died. Her husband, 52, and daughter, 24, suffered minor injuries and were taken to Te Kuiti Hospital.
King Country locals say the intersection, 10km north of Te Kuiti near Waitomo, is notorious for crashes.
Sergeant Warren Shaw said the campervan driver made a right turn directly into the path of the northbound truck-and-trailer unit, which had the right of way.
