Mr Kircher confirmed on Monday he would nominate someone at tomorrow evening's inaugural council meeting, but he would not indicate which councillor was his preferred choice.
The Waitaki District Council website shows the inaugural council meeting will include the appointment of the deputy mayor among a host of other ''formalities'' including the inauguration of the new council.
''There will be important cultural elements to this year's inaugural council meeting, including a mihimihi by Ngai Tahu, the singing of the national anthem, a Pasifika cultural dance, and a Samoan lotu (prayer),'' the council website says.
Council chief executive Fergus Power would chair the meeting until Mr Kircher officially renewed his role as mayor, receiving his mayoral chains from a senior representative of Ngai Tahu, it said.
In the last triennium Melanie Tavendale served as deputy mayor. This year, for the second election in a row as the youngest successful candidate she finished at the top of councillor polls across all wards with 4268 votes.
