I heard an interesting theory on this saga the other day (from someone who seemed to really know their stuff). He said that all the grounds in NZ and aussie were talking to each other about the clean stadium issue. The aussies were having as much trouble as NZ in achieving this. The didn't see it as a huge problem because the RWC had demanded clean stadiums for the last world cup in england and hadn't got them, but had accepted it wasn't possible. NZ had therefore expected australia to tell the RWC they couldn't deliver clean stadium, just like NZ were going to do. At the last minute the aussies managed to pull together a deal and put forward their proposal and NZ were basically shafted by them. Would love to know how much of this is true, but given what has happened it wouldn't surprise me. I am sure there is more to this saga than we have heard so far.
