The Cadogan brothers are the latest mayors in the South to confirm they want to lead their districts for another term.
Central Otago Mayor Tim Cadogan said he had strived to bring the community and the council together and the public had become more engaged since he took on the role almost six years ago.
The population had grown by about 4500.
Covid-19 "threw everything into a tailspin" this term, but dire economic predictions had not come to pass and the district was facing a labour shortage, rather than high unemployment, he said.
Sweeping changes were happening as central government pursued reform of Three Waters, resource management and of the local government sector directly.
"Councils have never faced such a wave of reform and experience is needed to make sure we ride that wave as best we can, rather than have it break over us," Mr Cadogan said.
Older brother Bryan Cadogan is seeking a fifth term as Clutha mayor.
He agreed significant challenges loomed for local government and said he was well positioned to respond effectively in the best interests of the district.
He was not yet satisfied the Clutha district was all it could be and said he had more to give.
There had been population growth in his district, too, and he was proud of efforts made to get people into jobs.
Bryan Cadogan this week remained stuck in Australia with Covid-19.
He spoke yesterday of feeling tired and experiencing tightness in his chest and headaches.
He remained keen to fight for what was best for the district, he said.
Dunedin Mayor Aaron Hawkins, who has also had Covid-19, confirmed last weekend he wanted a second term.
Other incumbent mayors in the South intending to seek re-election include Tracy Hicks in Gore, Gary Kircher in Waitaki and Sir Tim Shadbolt in Invercargill.
Southland Mayor Gary Tong is to challenge Sir Tim for the Invercargill mayoralty.
Queenstown Mayor Jim Boult has not yet said if he will seek re-election.
