In June, Mr Geddes, who was first elected to the role in 2001, announced he would not be seeking re-election.
Speaking to the Queenstown Times last night, Mr Geddes said he was feeling "a little nostalgic" and there was "no question" he would miss his job "for a short time".
"I've tried to stay very much focused on being the mayor right up until 5pm [tonight].
"That's one of the reasons why Sally and I haven't made any firm plans as to what we do [next].
"I felt I really didn't want to get distracted from continuing to meet all the commitments that come with being the mayor ... but it would be foolish to say you weren't going to miss a role you've been in for nine years."
Despite openly admitting being "one of the most private people" before first being elected, he said what he would miss most was the contact with people.
"I'm going to go back to being a private person, but I think what I'll miss the most is the contact with the people - the staff, the other councillors, the media funnily enough ... the contact with the community associations, the volunteers."
At his last full council meeting this week, Mr Geddes became openly emotional while presenting a long service award to Cr Gillian Macleod - who also is not seeking re-election.
The moment "caught me by surprise", he said.
"Gillian and I came on to the 2001 council in exactly the same circumstances.
"Gillian has been a very positive member of council and can look back with a great deal of pride."
Cr Macleod had been involved in the district entrance study, urban design panel, waste minimisation strategy and community housing trust and had been a promoter of plan changes to drive a better quality of development in the district. She had also contributed to the Queenstown town centre strategy and several working parties, including the renewal of street-scapes, he said.
"As I was walking around the table to present her with her award, I was thinking about all of those things and when I got to her, I couldn't get it out.
"It was a bit emotional - but I told her all of it later."
Mr Geddes said he was "quite determined" to avoid commenting on decisions made by the next council.
"This role ... is difficult enough anyway without having people who have previously been in the position making comment from the outside."
But he did have some words of wisdom for the new mayor.
"I think the really important thing about being mayor is that you have be be able to command respect of every section of the community so that everybody is comfortable coming to sit down with you ... and they don't feel they're going to come into your office and not get a fair hearing.
"It's about being impartial and being able to take part in mediation, discussion and resolution."
Mr Geddes and his wife, Sally, who had been "very, very supportive" of him and had embraced her role as mayoress, would wait until Sunday to talk about their future plans, which could include an overseas holiday.
