Suva Volleyball Association secretary Sam Rabuku said yesterday's tournament was the build-up for the Battle of the Powerhouses which will be held this Saturday at the FMF Gymnasium in Laucala Bay.
"Despite unfavourable conditions this (yesterday) morning, the Suva volleyball games committee continued with the games," Rabuku said.
"The games were delayed but the turnout was outstanding.
"A total of 16 teams in the men and five in the women took part."
Rabuku said the Battle of the Powerhouses competition between Suva and Raiwai was building up into an exciting clash.
"Looking at (yesterday's) games, the upcoming Battle of the Powerhouses will be an event not to be missed," he said.
"The tournament was just a feature of what to expect this Saturday so hope to see a lot of Raiwai, Suva and volleyball supporters there."
The Raiwai men's team won the major tournaments last year.
