I had the crowd at 200 for last year's one. Aucklanders didn't care about it enough to arrive hours in advance, somewhat understandably, and very few people were silly enough to fly up from Otago. This will likely be the biggest thing on Nelson's footballing calendar, so good decision IMO.
Edit: Related - Auckland must be the only side not to have players from their youth team last year not represent their squad this year. At least from the final, I can't see any player who has made an apperance this season in the game-day suad.
