The New Caledonian Army Forces were quick to act, sending a patrol plane last Friday to look at the extent of the damage in Vanuatu.
On Sunday the territory's forces arrived on the cargo ship D'Entrecasteaux in the capital Port Vila.
A supply ship is also delivering supplies from Port Vila to Tanna and other islands.
The ship will assist in road clearance, provide drinking water and give medical response.
General of the Army Forces of New Caledonia Valerie Putz says the structural damage on Tanna Island has been fairly minimal.
