It is uncertain whether the Central Coast Mariners (McGlinchey) or the Melbourne Victory (Barbarouses) will agree, while the English and European clubs are likely to take some persuasion.
The planning and preparation building to November has left a lot to be desired.
NZF has known since July 2011 that it was likely they would face Concacaf opposition for the spot at the World Cup.
They've had 18 months to plan the build-up, as Fifa windows are locked in years in advance.
Given what is at stake, there was time to plan the best possible programme with no detail overlooked. That is where winning - and high performance - begins. Instead there has been a rushed, last-minute schedule thrown together, with players uncertain about what was happening until last week.
They are now expected to take on the might of Mexico (or Panama) with far from ideal preparation.
The OSN Cup in Saudi Arabia was a difficult assignment with trainings just after dawn and games late at night due to the heat. In between times players consigned to their hotel for security reasons.
International games are notoriously difficult to arrange but things needed to be locked in earlier, but NZF has seemed unwilling, or unable, to spend the money required. That reflects badly on the planning and leadership of chairman Frank Van Hattum and his board. Remember, NZF declared a surplus of $7.7 million after the 2010 calendar year and said there was a $2.5 million war chest for international football.
Now they are cutting corners ahead of the most significant week in four years.
It's a shame. With the likes of Marco Rojas and McGlinchey, the All Whites have a team with more attacking flair than the 2010 side, as well as the usual defensive solidity, albeit without Ryan Nelsen.
