I'm having problems finding ANY reward seats available from LAX-RAR (and onward) when trying to book my miniRTW.

I've checked every day for weeks, and no seats seem to be open after July 7, 2013.

Does NZ only release seats for these segments a lot closer to the dates? I'm trying to find seats in mid November, but nada. For August all the way to the 330 day window.

Do they hold seats back for a long time? Am I missing something? Is this a difficult reward seat to book?

I've seen nothing in ANY class.
