A New Zealand Air Force Hercules on Rarotonga is currently being loaded with relief supplies for the cyclone battered northern Cook Islands and is expected to fly out this afternoon.
The Hercules arrived in Rarotonga earlier this week with equipment such as cherry pickers to aid the clean up from the three cyclones which hit the southern Cooks in February.
But, it has been pressed into service to get emergency supplies to Pukapuka and Nassau.
The New Zealand Aid Minister, Marion Hobbs, says while many houses have suffered extensive damage, the food and water shortage is more pressing.
"It is not so much that the houses have been damaged but that the contents of the houses have been taken out, so that the supplies going out on the Hercules are tinned food, coffee, biscuits,and fresh water, blankets, chainsaws, tarpaulins, clothes and medical supplies."
The plane has to land at Penryhn and an interisland ship will deliver the supplies to Pukapuka and Nassau - that will involve a two day voyage.
