I'm just worried that I'll book plane tickets to Christchurch and then have a possible warmup show announced on the north island. That would be, well, annoying!
Also I'd assume if there will be 2nd shows announced in all three cities then the 2nd show announced for Christchurch would in fact be the Saturday - the day before the one about to go on sale.
Do you think going to all shows is greedy? It would mean someone else in NZ misses out.. What to do?? I think I'll buy tickets to all shows and deal with problems as they arise.
