That wouldn't be too much of an issue, don't forget if skynews is involved, and there seems to be a bit of talk about a 2nd nz team from many ex-player kiwis (pros &cons) but still talk regardless which could draw potential owners, as opposed to only freddys talk regarding perth...
Auckland 2 works for a number of reasons, it can create a city based rivalry, (cross town) Auckland is already more rugbyleague minded than any of the other cities/regions of NZ, as NZ is all RU, so expanding that, then a possible nz3 elsewhere might take, if the Aucklands Rugba leg is successful, and it has the population to take on 2 teams, where any other area based in NZ, could barely scrape one, which is why we keep hearing of a Christchurch and Wellington split of games, for a potential "southern NZ" team, which im fine with, but im also seeing how practical having a shared city rival approach could work too, a new team in Auckland could be a great excuse to rebuild the stadium too, or let the warriors travel NZ, leaving the other team still having a presence in Auckland every fortnight, or not and having a game every week in the largest city in NZ
