A Hamilton man says he must have fallen asleep after celebrating his birthday before veering off the road and crashing head-on into a car, killing its passenger.
Justine Anderson was sitting in the front seat of her partner, Nick Horwood's Nissan Skyline, when Girish Mahadev Kale's vehicle abruptly swerved into the southbound lane they were travelling in.
Miss Anderson, 24, died of her injuries at the scene.
In the Hamilton District Court today, Kale, 42, pleaded guilty to one charge of careless driving causing the death of Miss Anderson and careless driving causing injury to his pregnant wife, Anagha Kale, after the crash on December 5, last year at Karapiro.
Miss Anderson, a former Cambridge High School student, and Mr Horwood had been visiting her family in Cambridge and were on their way back to Tauranga when the crash occurred.
