A driver has died after their car collided with a truck north of Hamilton overnight.
Emergency services were called to State Highway 1, Ngaruawahia about 11pm after a car and a truck collided.
Police said the car has then veered off into a roadside drain, while the truck came to rest on its side.
The sole occupant of the car died, while the driver of the truck suffered moderate injuries.
Both lanes were closed for a period overnight but have since reopened.
The accident was one of two fatal crashes in Waikato last night.
Earlier, one person died and another was injured following a two-car crash at Peacockes Rd, Tamahere, just south of Hamilton, about 8pm.
The Waikato Police Serious Crash Unit is investigating the cause of the crash.
