A man has lost his wife after crashing into a truck in the King Country overnight.
The 33-year-old driver survived the head-on collision that killed his 27-year-old wife.
She was sitting in the front passenger seat as the pair travelled home through the Waikato on Monday night.
A car and truck crashed at the intersection of State Highway 3 and Awatane Rd.
As they headed northbound not far from Otorohanga, it appeared the driver failed to take a corner and crossed the centreline on State Highway 3, Waikato police Senior Sergeant Will Loughrin said.
Their vehicle crashed head-on with a heavy haulage truck and trailer travelling southbound, at the intersection of Awatane Rd at 11.11pm.
The woman died at the scene.
Her husband was initially trapped in the driver's seat and had to be cut out by firefighters from Otorohanga, Fire and Emergency northern communications shift manager Daniel Nicholson said.
The man was taken into the care of ambulance and transported to Waikato Hospital in a serious condition.
The truck driver was uninjured.
SH3 was closed between Te Awamutu and Otorohanga while a serious crash investigation was undertaken.
By 7.15am on Tuesday it had reopened.
