Council cost-cutting could result in the Warriors shifting to Eden Park and speedway going to Mt Smart Stadium.
Regional Facilities Auckland is proposing moving speedway from Western Springs instead of upgrading the Warriors' home ground.
The Warriors would then move to Eden Park, to make better use of the city's biggest stadium.
Warriors CEO Wayne Scurrah says he only found out about the plan through the grapevine.
Scurrah says he needs more details and many factors need considering.
"What are they proposing, because we don't just play our games here at Mt Smart, but we're based here as well and in many ways the amount of time we spend training and preparing for matches are more important than the 12 we play in Auckland.''
He's uncertain about the viability.
"We need to know a little bit more. We've lived all of our lives at Mt Smart Stadium, since 1995, and we still remain committed to Mt Smart Stadium, so I guess we need to understand from the city what is the master plan of the stadium.''
The speedway contract with Western Springs ends in 2014, but the Warriors have six years on their tenancy of Mt Smart.
