The business owner asked councillors to get curious about what is in the gallery cupboards and set expectations for the Te Manawa Museums Trust, which runs the gallery, to display more of the collection and generate revenue.
"We've got an asset down there that's not being utilised well enough."
Monthly exhibitions would be ideal but may not be realistic given Te Manawa's current level of resources.
Per capita gallery visitor numbers were lower than other regions. "And that's because we just don't have enough energy and passion running in there."
Cr Vaughan Dennison said he attended the Wildlife Photographer of the Year exhibition and the art gallery seemed "quite barren".
Referring to Te Manawa chief executive Andy Lowe's use of the word tension in his 10-Year Plan submission, Dennison asked how Crowley would describe the relationship between the art society and Te Manawa.
Crowley said the committee is positive about the way it is moving forward and sees its role as to support Lowe and his team. The committee was only looking forward, not backwards. He thought tension related to allocation of resources as Te Manawa is stretched.
In his submission Lowe wrote: "We would like to make it clear that there will always be tension in working with the founding societies [art, museum, science] as we move into the future. The board and staff of Te Manawa will continue to work collaboratively to meet the aspirations of our societies where possible."
