i believe that was an option once, but they chose to go ahead with the venue at Kilbirnie
Think was the Kilbirnie type venue and was meant to be over the concourse, rather than 15,000 outdoor. The logical spot for an outdoor is across the road from the stadium where the logs are and a new log depot to go North of the ferry terminal. That move has already been mooted a number of times, albeit without the stadium. However no one is going to support that while they all have an investment in Westpac.
What it needs is Westpac to be flattened by a VERY localised earthquake or a run away train so you can build a 35k rectangular stadium with a 15k lower tier for smaller crowds.
Bu but what about the All Blacks? and the 7s? (for Wellington not for me. I don't care for either)
