The All Whites could be without several top players - including Winston Reid, Tommy Smith, Michael McGlinchey and Kosta Barbarouses - for at least two of three build-up matches before next month's World Cup qualifying matches.
New Zealand Football finalised their plans for the October window last week, announcing games against Mexican and American club sides (Queretaro and Chivas USA), as well as a match with Trinidad and Tobago, but they may not have their top side available.
Their first scheduled game, originally against Mexican club Queretaro is on October 9, outside the official Fifa window (October 11-15), so clubs don't have to release their players. There is also no obligation to release players for a game against a club side; Fifa rules apply only to sanctioned international matches.
Only the goodwill of the New Zealanders' respective club sides will allow many to be present for all three matches. It's asking a lot. Players will fly to the US, play two games in four days, then make a return trip to Trinidad and Tobago for a third game before returning to their clubs.
The Phoenix look likely to release their national players, despite it causing a headache for the first two rounds of the A-League. They'll have a depleted squad for the first round against the Roar and their All Whites will only arrive in Sydney 24-36 hours before the round two match against Western Sydney Wanderers on October 20.
