The circumstances surrounding an accident which claimed the life of a 4-week-old baby boy, and caused only minor injuries to others in the car, will be investigated by a coroner.
The baby was travelling with his mother, father and two older siblings on State Highway 1, between Pareora and Timaru yesterday, when their car collided with a four-wheel-drive about 12.30pm.
All five members were taken to Timaru Hospital. The baby died at about 11.30 last night.
His two older siblings - a 2-year-old and 4-year-old - his mother, 27, and his 28-year-old father were discharged yesterday.
Waimate police Senior Sergeant Mike van der Heyden said an initial scene examination indicated all family members were wearing restraints - however police arrived after the family had been removed from their car.
