The Warriors remain hopeful of playing games in New Zealand this year, despite the cancellation of their first scheduled homecoming match.
That fixture, set down for June 18 against the Penrith Panthers, was going to be their first game on home soil in more than 1000 days.
But the club reluctantly pulled the pin on Friday, in the wake of last week's government announcement about the phased reopening of New Zealand's borders.
"We've always made the right call based on the facts that are in place now," said Warriors chief executive George. "We can't speculate and the government have given us no confidence that transtasman sport can take place within that timeframe. So in the best interests of stability, our footy team and players we are withdrawing the game from New Zealand in June."
George told the Herald last month that he was already working on a 'plan B' for the five scheduled Mt Smart fixtures, given the ongoing uncertainty.
