Mr Crosby told the Bay of Plenty Times the role was necessary after changes to the Local Government Act gave mayors greater powers and more responsibility.
The changes meant mayors around the country were legally responsible for driving council plans and budgets and could be held individually accountable for key decisions.
Mayors from cities similar in size to Tauranga have backed the job, saying central government expected "far more" from mayors .
Hamilton Mayor Julie Hardaker said growing cities such as Hamilton and Tauranga changed rapidly and it was a huge job for city leaders to be across everything. She said mayors had to make good decisions quickly and needed the support of policy and communications specialists.
"This kind of support, which is really a chief of staff sort of role, is vital these days in fast-growing cities," she said.
Ms Hardaker said she had five people supporting the mayoral office.
Dunedin Mayor Dave Cull said there was a need for mayors to have policy and communications support.
Mr Cull said he did not have one person advising him like Mr Crosby but relied on a team of 10 policy and six communications managers. TCC has 2.7 strategic planners and two policy analysts in its strategy group and five communication staff.
"... If you choose to have one individual doing it, like Stuart is seeking, then that is up to the council but one thing is certain, mayors need this resource to do the job properly," Mr Cull said.
A Local Government NZ spokesperson said councils such as New Plymouth had hired policy advisers and some were setting up offices to deal with the extra work that came after changes to the act.
Applications for the role close at 9am today. Mr Crosby could not comment on how many people had applied or if there were Bay candidates.
