COLO North thumped Colo East 20-5 to secure its first B Division win at Garvey Park, Tavua yesterday.
The side was in top form scoring four tries to one to record a bonus point win.
Colo North which comprised teams from Waikubukubu, Nadarivatu and surrounding areas outsmarted the West team which featured players from Bukuya and the surrounding villages.
Tournament official Joeli Tubu said the game was physical and exciting as both teams were desperate for a win.
He said Colo North played structured rugby and fully utilised its possession to win the game.
"Colo West had no answer to counter their opposition and managed to score only try," he said.
"The game also exposed some wonderful talents as both teams were desperate to win the game."
Tubu said Colo North would be tested when it batted against the in-form Ra outfit in their next pool game.
Ra will first play against Colo West before battling against Colo North next week to determine the winner from their pool.
