"With Baseball NZ, we have looked at various sites - out west obviously, down in South Auckland, around the Penrose area, certainly Western Springs in the early days in the overall investigation into the regional stadium plans," Nesbit said.
"From a demographic perspective and a catchment location, I think it is fair to say Baseball NZ prefer to be based on the Shore. At various times, we have looked at opportunities maybe identifying a footprint in or around QBE or adjacent to that site.
"There is a lot of water to go under the bridge. The investigation is not just on existing stadium land but also adjacent pieces of land."
Basically the plan is for RFA to find the land on which the stadium could be constructed and then it would be up to baseball to largely fund the building on it.
Baseball New Zealand chief executive Ryan Flynn thinks they have the support needed to get it built.
"We have commitments from the World Baseball Softball Confederation, from Major League Baseball and other parties domestic and international, who have confirmed their support financially to help us get this over the line," he said.
Flynn is confident they can enter the league by 2019-20 but hasn't ruled out entering next year.
