RED Rock and Yamacia are among the top teams that will participate in the SPS Nakoronubu 7s at the Ba Market ground on Saturday.
The day-long tournament has attracted a total of 32 teams.
The purpose of hosting the tournament is to generate funds to upgrade the gymnasium for the Sorokoba and Sasa clubs which are part of the Ba Rugby Union.
Tournament organiser Solo Vakanawa said they realised the need for a proper gymnasium for weight training in order to strengthen the upper body of the players.
Vakanawa said the tournament was sanctioned by the Fiji Rugby Union.
"The cup winner will receive $2000," he said.
"The cup runner-up will get $800. There will be eight pools in total.
"The winner of the pool will go into the cup competition, the runner-up goes into the plate competition while the third placed team goes into the bowls competition."
Vio, Sorokoba and Speedwing are the other known 7s clubs registered for the tournament.
The plate winner will receive $600 while the runner-up will get $300. The bowl winner will collect $300 while the runner-up will receive $100.
