Maika Sivo and Viliame Kikau both scored a try each for the Panthers as they thrashed the PNG Hunters 42-18 to win the Intrust Super State Championship.
The competition is the second grade in the NRL.
Kikau has automatically earned his spot in the Vodafone Fiji Bati for the World Cup after playing nine NRL first grade games for the Panthers this year.
Sivo on the other hand is likely to feature for the Overseas Bati against the Fiji Residents in the Battle of the Bati this Saturday.
Fiji National Rugby League CEO Timoci Naleba says the Bati selection criteria require an automatic selection for any player who has played more than eight games in the NRL first grade.
The Battle of the Bati will be at 3pm Saturday at the ANZ Stadium.
Meanwhile the Kangaroos and the PNG Kumuls will play the Vodafone Fiji Bati at the ANZ Stadium next Saturday.
