Taumalolo switched allegiances to Tonga in the days leading up to the World Cup squad announcement, with three others following suit.
Blair believes Taumalolo should've owned up to his decision to switch to Tonga for the Rugby League World Cup and called coach David Kidwell.
"Own up to what you want to do, I don't think texting someone the way to go about it and texting the coach or Shane is not the way to go about things. I think if you were man enough you'd come up make the phonecall and tell them."
He's also filthy with Warriors centre David Fusitua who is understood to have committed to Kidwell four hours before the announcement, then withdrawing.
"He's made a bit of a mockery of the game when it comes to making those decisions, to call up half an hour or an hour before the team is announced , when they're in the team, is quite heartbreaking."
Blair says they feel let down and it would take a lot of rebuilding to trust those players again in a Kiwis jumper, should they make themselves available in the future.
Some significant relationship rebuilding will be required if Jason Taumalolo wants to play for the Kiwis again in the future.
"When you play a game of football you rely a lot on trust and the brotherhood and trust, and at this stage it feels like we've been let down."
