MANU Samoa can bid for the Southern Hemisphere's 15th Super rugby spot.
When formally made, the bid could signal the end of the Pacific Islands Rugby Alliance.
The Samoa Rugby Union has made it clear it wants to do away with the Pacific Islanders tours.
Samoa prefers playing Tests on its own, saying that is the best way for island nations to build their rugby union base.
PIRA chairman Keni Dakuidreketi yesterday confirmed Samoa had spoken about a possible withdrawal.
"The body that looks after the combined team is Pacific Rugby Limited, on which the three unions are equal shareholders of," Dakuidreketi said.
"Samoa has expressed its desire to disengage from the PRL."
Dakuidreketi, the Fiji Rugby Union acting chief executive, said a decision would be made soon.
Samoa Rugby Union chief executive Peter Schuster referred all queries to Dakuidreketi.
The South Africa, New Zealand and Australia Rugby Unions have invited Samoa to bid for the 15th Super rugby franchise.
But SANZAR has made no such offer to Fiji and Tonga.
The Samoan Rugby Union had been provided with the expression of interest document so that it can consider whether it wishes to mount a bid.
SANZAR has written to Argentina, Canada, Fiji, Japan, USA and Tonga and advised that, while SANZAR is not considering them as potential expansion locations for the 15th team, it sees the change in the competition format from 2011 as a first step in positioning Super Rugby to allow for future opportunities.
Schuster said they had decided not to bid for it as yet but could consider it in the future.
Dakuidreketi said Samoa's wanting to drop out of PIRA did not have anything to do with the bidding invite.
"My understanding is that they have expressed interest through a consultant they have hired to be part of the bid," Dakuidreketi said.
