The death would be the 13th on Western Bay of Plenty roads this year. It was the eighth death nationally for this school holiday period.
A red and yellow cover was placed on top of the red car where the deceased person lay, just 300 metres from Kaimai School.
Emergency services swept sawdust across the road at the crash site to absorb the petrol which had leaked from the cars.
Members of the public helped direct traffic around the scene where car parts and glass lay scattered across the road.
Just before 5pm, the road was completely closed to motorists while the Serious Crash Unit investigated. It was reopened about 90 minutes later.
A Police Media Team spokeswoman said the name and age of the deceased person would be released when next of kin had been informed.
"That could be any time, sometimes it takes less than a day, sometimes up to a week," she said.
Kaimai School Principal Dane Robertson said it was not the first crash outside the school and he feared it would not be the last either.
Mr Robertson said he had previously campaigned to have the speed limits outside the school slowed at the start and end of the school day, like they were for schools in urban areas.
"The fact the road has not been changed [for safety], leaves me speechless. I feel like I am beating my head against a wall.
"This crash happened [at] 3.30pm on Friday afternoon, that's not far off school finishing time and it's not the first accident within 300m of the school.
"I thought to myself, were there any staff leaving the school and on their way home? We have students who live in the area. Were they or their parents in it? It brings it close to home, as all accidents do."
Mr Robertson said it always played on the back of his mind there would be another crash and having the speed limit changed remained a high priority for the school, he said.
