The Vanuatu authorities say water in the capital, Port Vila, is up and running again and all roads on the island of Efate will be cleared by Saturday.
The spokesperson of the National Disaster Management Office, Benjamin Shing, says roads in Port Vila will be cleared by today of all the debris from Cyclone Pam.
Mr Shing says on Tanna, which suffered a direct hit by the cyclone, many key roads have been cleared.
He says it was fortunate a Chinese company had recently sent heavy equipment to the island for a project.
"We used all their heavy machinery, they have cleared all the roads - from Lenakel all the way to the airport, from Isangel all the way to the airport, and they also cleared from the airport, from Whitegrass all the way to Whitesands and the hospital area. So they have cleared all those roads, which is quite fortunate."
The National Disaster Management Office spokesperson, Benjamin Shing, says however the crews are at risk of running out of fuel.
