A man who died after crashing his car into a tree in the Waikato was not wearing a seatbelt, police say.
Waikato road policing manager Inspector Freda Grace said police were searching for a stolen car near Ngaruawahia when they came across the single vehicle crash shortly after 4am today.
"It appears the male driver and sole occupant of a northbound car has lost control on Great South Rd, near the intersection with Havelock Rd, and collided with a tree.
"The driver, who was not wearing a seatbelt, was found alive but in an unconscious state and died a short time later in an ambulance."
Mrs Grace said work was currently underway to formally identify the man and notify his family.
