Osea Kolinisau will lead the Olympic and World Series champions' squad, which includes fellow gold medallists Jasa Veremalua and Samisoni Viriviri.
Fiji Rugby Union CEO John O'Connor said even with some players overseas there is still a huge pool of talent available in Fiji.
"I am happy that we have been able to identify these players and bring them into camp to prepare them for the Oceania 7s," he said.
"They have shown a lot of progress in the two weeks of camp which proves their selection into the team."
