FIJI rugby under-20 reigning champion Nadi is aiming to maintain their status in this year's Skipper Tuna competition.
The side had successfully won all their three games and are on track to defend their title.
This weekend the jetsetters will be tested by first timers Vatukoula in one of the feature games of the week.
Nadi manager Jeff Tamata said defending the title would be tough.
He said players had been urged not to underestimate the miners.
"We know that this is the first time for Vatukoula to feature its U20 team and we will not treat them lightly," said Tamata.
"We will take all games as it comes and the boys know what is required of them.
"Our aim this season is to defend our title and we will give our best in all the games."
Tamata said the side would feature six players from last year's winning team.
Nadi is second on the points table behind arch rival Nadroga after three rounds of competition. The side beat Naitasiri 10-0 in the first game, thumped Northland 27-9 in the second game before outclassing Ovalau 29-14.
