A Cook Island primary school damaged in a fire on Sunday local time is resuming classes at a nearby school.
On its facebook page, the Avatea Primary School in Rarotonga says it lost nine rooms in the blaze including the arts store room and library.
It says thousands of dollars worth of books, computers and teaching resources have been destroyed, including drum sets and costumes.
The neighbouring Nikao Maori school is hosting the Avatea students in their classrooms and library.
The New Zealand Fire Service is helping the investigation and Cook Islands Rescue Fire Service Chief, Nga Jessie, says the investigations are almost complete.
He says the cause of the fires is not known but if they were set deliberately, the case would be handled by the police.
