Some of the evacuees who fled the Manaro volcano are now being sheltered on the two islands, while the vast majority are on the big island, Santo.
UNICEF's country representative, Andrew Parker, said supplies are still being distributed to the islands and the evacuees are doing alright.
"Students that are relocating from Ambae into Maewo are certainly being supported with personal hygiene kits, and blankets, mosquito nets, and lights and so on," he said.
