"This is an absolute tragedy for a number of families and the community as a whole.
"All the youths are local to the area and our thoughts are with the family and friends of all those involved.''
Police officers are now investigating the circumstances of the crash and are calling for any witnesses of a white Toyota Wish vehicle in the Ngaruawahia area - between 5pm to 6.15pm - to come forward.
Police want to hear from anyone who might have seen a Toyota Wish similar to this one after the Ngaruawahia crash.
"It is too early to determine what may have caused the crash as there may well be a number of contributing factors,'' Ambler said.
"While our thoughts are with the families of those involved, Police are urging drivers to exercise caution on the roads, to drive to the conditions and to ensure people behind the wheel know their limits."
