The 2025 Otago Regional Council election was a local election held from 9 September to 11 October in the Otago region of New Zealand, as part of that year's regional council elections and other local elections held nation-wide.
Voters elected 12 regional councillors for the 2025âÂÂ2028 term of the Otago Regional Council. Postal voting and the single transferable vote system were used.
Following a representation review, the Otago Regional Council will be made up from 12 councillors elected from four constituencies for the 2025âÂÂ2028 term: Dunedin (five councillors), Dunstan (four councillors), Molyneux (two councillors) and Moeraki (one councillor). This will be one less councillor representing Dunedin and one more councillor representing Dunstan compared to the 2022âÂÂ2025 term.
The council also determined to switch from first past the post voting and instead hold this election using the single transferable vote (STV) method.
In late May 2025, the Green Party of Aotearoa New Zealand confirmed it would be running several candidates in the 2025 Otago Regional Council, Dunedin mayoral and Dunedin City Council elections. Incumbent Alan Somerville is standing on the party ticket and incumbent Elliot Weir is standing as a Green-endorsed independent.
In mid August 2025, the Vision Otago ticket was formed on a platform of reducing local government rates. Members of Vision Otago included former MP and councillor Hilary Calvert (Dunedin), Carmen Hope (Molyneux), Cr Michael Laws, Cr Gary Kelliher and Nicky Rhodes in the Dunstan ward.
The Dunedin constituency returned five councillors to the regional council.
The Dunstan constituency returned four councillors to the regional council.
The Moeraki constituency returned one councillor to the regional council.
The Molyneux constituency returned two councillors to the regional council.
