"[There is] absolutely a positive attitude about where we're heading and I'd like to see that continue."
Meanwhile, after nine years on council and six as deputy mayor, Nigel Belsham said he will not run for council this year, preferring to focus on his growing business.
In light of Belsham choosing not to continue on council, Watson said there needed to be some thought about who the next mayor would be after his time.
"Part of my thinking is we need to absolutely go through a process of looking for my replacement."
He said it was essential whoever that was had a stint at being a councillor or another type of similar office.
Watson said there were enormous challenges with local government facing almost "any reform you want to mention".
Whether it was the Three Waters reforms, the Resource Management Act reform - there were some big changes happening in local government.
Belsham said his business BJW Motors was going through a significant growth period - taking on new staff and building a new workshop - and he needed to put his attention there.
"My focus has to be on the business."
He did not rule out coming back to local government in the future.
"I've enjoyed my time in local government and the changes the district has gone through over that nine-year period has been fantastic. I would like some more involvement but later on."
Belsham, who is a Central Ward councillor, said the district had in the last three to five years become massively more attractive to live in.
"I can take some heart the direction council has moved in has had some influence on that and also the attraction of housing growth and new building in our district is something I've taken away from my time on council."
Another Central Ward councillor, Fi Dalgety, said she was keen to run for a second term.
In the Southern Ward, councillor Brian Carter said he would throw his hat back in the ring for a second term.
"There are projects that have been started I wish to see finished off."
Fellow Southern Councillor Waru Panapa, based in Rātana, said he would not be standing, saying that he struggled with the "nitty gritty" of being a councillor.
He said he planned to focus his attention on mending rifts between the Rātana Church and the movement, which he said had a significant role to play in social and spiritual healing around the country.
Panapa said the new Māori Wards - Tiikeitia ki Uta (Inland) and Tiikeitia ki Tai (Coastal) - provided a crucial opportunity for Māori to become more involved in local government.
Southern Ward councillor Coral Raukawa could not be reached for comment.
