UNICEF's field office chief in Vanuatu says children displaced by the volcanic eruption on Ambae are in urgent need of support.
Andrew Parker says children are one of the groups most at risk during disasters.
He says more than 3000 school aged children will need to be re-enrolled in primary and secondary schools on Maewo, Pentecost and Santo.
Mr Parker says the 1000 secondary students were given priority by government with some coming to end of year exams and have been housed in boarding schools in neighbouring islands.
He says the 2000 younger primary students are to be absorbed by schools in and around the evacuation centres.
However he told Dominic Godfrey many of these schools are being used to house the displaced.
