I still look at what Auckland has with their 3 'stadium' and we are still 2 too many. How is a town with 1/3 the population going to work 2 of them (football specific or otherwise) especially when you still have the Basin. If everything goes to this new place except for Hurricanes, ABs and cricket, you'll be left with an stadium that may host 18 games a year. White Elephant!
I'm not convinced Auckland has two, too many. Maybe just one (and incidentally the location of all of them are significantly worse the Westpac or Petone in terms of ease of access). Isn't there actually some restriction on the number of events allowed at Eden Park per year? I don't think the Warriors would exist if Auckland only had Eden Park.
Also as an aside I don't see any problem with anyone from Westpac stadium giving us their point of view.
