Background

Electoral system

The election was held using the Single Transferable Vote system. Voting took place by post and through the returning of completed voting papers to ballot boxes.

Campaign

One key election issue was the proposed landfill site at Smooth Hill. While the incumbent Mayor Jules Radich supported the Smooth Hill landfill site, mayoral candidate Andrew Simms and his Future Dunedin ticket opposed the new landfill site and campaigned on reversing the Council's decision to acquire the site for rubbish disposal.

Endorsements

On 17 June 2025, former Team Dunedin Councillors Andrew Whiley and Kevin Gilbert endorsed Sophie Barker as mayoral candidate. They along with fellow Team Dunedin councillor Brent Weatherall declined to endorse Jules Radich for a second term as Mayor of Dunedin.

Results

When progress results were released on the afternoon after voting closed, it was clear that Dunedin would get a new mayor, but it was unclear who that was going to be. Radich, the incumbent, had come fourth. Sophie Barker had a slim margin of 105 votes over Andrew Simms, with Lee Vandervis in third place.
With the release of the preliminary results Sophie Barker was confirmed as the winner, having a clear lead of 726 votes over Andrew Simms. Final results increased this to 898.
Overall turnout for the election was 45.47%, with 43,310 voting papers returned.
