A second child has died after a crash on Desert Rd, north of Waiouru on Good Friday.
Senior Sergeant Fane Troy, Bay of Plenty Road Policing, said one child died at the scene.
The second child died in Starship Hospital today as a result of injuries suffered in the crash, Troy said.
Another victim remains in a critical condition in Waikato Hospital.
Both children were correctly restrained in car seats.
The death brings the Easter weekend road toll to three, which was one more person than the total number of road deaths for the holiday last year.
Police said two cars and two truck and trailer units collided about 3.30pm between Waipakihi Rd and Rangipo Intake Rd.
Fire crews helped free victim from their vehicles.
Police remind travellers heading home from their Easter break to be patient, and watch their following distances.
A disregard for authority could be why those attending court are thumbing their noses.
