"Determined to avoid similar situations, New Zealand Football high performance manager Fred de Jong said yesterday that wherever possible matches would be played only in Fifa windows at which time the players must make themselves available."
De Jong, haven't you noticed that players aren't coming back during FIFA windows?
My take on the article (reading between the lines of the bit you left out) was that they would try to avoid arranging games not during windows/over the summer break, on the understanding from the players that they would stop the pissing about and avoiding playing during FIFA windows.
"As a compromise, NZF will try to avoid scheduling friendly internationals outside the windows and, if possible, leave the European summer break free to allow players to take holidays."
