Fiji captain Kevin Naiqama won't back down from a threat made by the country's World Cup heroes to boycott any planned Tests until a pay dispute is resolved as he intervenes to try and ensure money is released to the squad.

The popular Tigers centre has been forced to become involved in negotiations to recover $125,000 in prizemoney on top of daily allowances still allegedly owing to players from the World Cup semi-finalists, which has taken the gloss off Fiji's remarkable run in last year's tournament.

But Naiqama has also demanded that unless the Fiji National Rugby League's leadership step down at next month's AGM its current stars will refuse to make themselves available for selection in international fixtures.

It is understood the FNRL has belatedly started to release Fiji's World Cup funds to Rugby League International Federation intermediary Tas Baitieri, but the players are still awaiting payment after stunning New Zealand in the quarter-finals and surging into a final four showdown with Australia.
