Secretary So'oletaua Motuliki told RNZ Pacific from Port Vila last Thursday they were seeking funds to enable them to make the Games trip.
Motuliki said funding would be necessary especially if the Vanuatu Amateur Sports Association and National Olympic Committee (VASANOC) has to make the call on what sports teams might have to be left out.
This is because VASANOC might be restrained financially to send a full Vanuatu squad to the Games.
"The initial budget, unfortunately, is not what was observed initially," she said.
