A Red Cross worker in Niue says the immediate priority there is to ensure those people left homeless have enough food.
Douglas Clark from the Red Cross is leading a team to assess damage to the island.
He says it appears at least two hundred people have been left homeless and need food.
"Essentially these two or three hundred people, have no, apart from the two or days' worth of food which they've got, that can be salvaged, there is essentially no food for these people."
Douglas Clark says it will take about a week to assess the full extent of the damage.
But he says its already clear an enormous amount of work and aid money will be needed to rebuild Alofi and the infrastructure that was lost in the cyclone.
