The Easter holiday road toll stands at six, four more than last year's total.

Among those killed were two children in a crash between two cars and two truck-trailer units on the Desert Road on Friday.

The crash happened in the south-bound lane on Friday afternoon and forced the road's closure. Police said both of the children were correctly restrained in car seats.

The parents of the two children are in a stable condition in Waikato Hospital.

Another person was killed on Good Friday in the Bay of Plenty at Tirohanga near Opotiki.

On Saturday a person died in Rotorua following a crash between a car and a motorcyclist.

Two more people were killed overnight in a head-on smash on State Highway 10, near Kerikeri. Two others from that crash were taken to the Bay of Islands Hospital.

The holiday period ended at 6am today.
