Charles Piutau has been told by New Zealand Rugby he cannot play for the Blues next year.
The 23-year-old, who will take up a contract with Northern Ireland club Ulster halfway through 2016, wanted to play for the Blues before he left, and the struggling franchise was eager to take it up with New Zealand Rugby on his behalf.
In announcing his departure on a two-year deal, Piutau also expressed a wish to return to the Blues in a bid to represent the All Blacks again in the future.
He remains in the frame for this year's World Cup, but if he is not selected, New Zealand Rugby's response will leave a bad taste. It will also force him to consider other overseas offers before he moves to Belfast.
It is a decision by the national body which might prompt questions from the struggling franchise's supporters about how far it is prepared to be involved in the contracting of players while allowing the John Kirwan coaching saga to run. At the weekend, after a fortnight of reports about Kirwan's future and the revelations of an impasse at board level, New Zealand Rugby confirmed it would help mediate in the messy affair.
