Police say unrestrained youngster was sitting on mother's lap and overcrowding, speed and two bald tyres likely to have contributed to crash on rural road near Te Kuiti yesterday.
A baby who was unrestrained on his mother's lap when the car they were travelling in hit a bank yesterday has died.
Waikato district road policing manager Freda Grace confirmed this morning that police found the baby's car seat in the boot of the car but there was no room for it to be set up as the car was overloaded with passengers.
Four adults and a 3-year-old were all wearing seatbelts and properly restrained when the car crossed the centre line and hit a bank on State Highway 4 at Kopaki, Waikato around 8.30am yesterday.
"The baby was airlifted to Auckland's Starship Hospital with critical injuries following the crash but passed away early this morning," Mrs Grace said.
