The federation is due to announce its 23-player squad list tomorrow.
A larger playing party is currently training at the VFF Teouma Academy.
Team Manager, George Amos, said the unit is well prepared for the group matches being held in the second half of March against Tahiti, Solomon Islands and the Cook Islands.
