Thinking of going next year - hopefully to support All Whites but keen to go anyway.
Trying to figure out a plan of attack for ticketing - the first round of ticket registration opens on 20 August and runs to 10 October. You register interest, specifying your preference (match, team or venue tickets), and then tickets are allocated randomly.

A decent explanation of how it works is here: http://www.grantland.com/blog/the-triangle/post/_/id/69307/so-you-want-to-buy-world-cup-tickets
My thinking is to register interest in single match tickets for the semi and final (shit's show of getting one I know but you never know).
Assuming the All Whites qualify it would be Russian roulette registering for a venue ticket before the draw in November i.e. in this first ticketing round (no one of course knows what group they would be in (except maybe Sepp)).
I could register for a team specific ticket for the All Whites but then, if they don't qualify, you’re stuck with tickets to follow Panama, Honduras or whoever.
If When the All Whites qualify a % of their group game tickets will be allocated to All White's supporters (no idea how that would work) so you should be able to pick up group game tickets from the NZ allocation - apparently, for this tournament, tickets are not being allocated to travel agents so you can't get them by buying travel packages.
I'd be interested in how others are thinking this through.
