Southgate's Political Career in Hamilton Local Government
The landscape of local governance in Hamilton has been significantly shaped by the leadership of Southgate, whose career spans over two decades of public service. From her early days in regional administration to her tenure as the city's mayor, her trajectory reflects a persistent commitment to the Waikato region.
Early Career and Regional Leadership
Southgate began her journey in local government as a councillor on the Waikato Regional Council, a body responsible for environmental and regional planning. She served in this capacity from 2001 to 2016. Her leadership capabilities were recognized by her peers in 2013 when she was elected as the council chair, securing the support of eight out of fourteen councillors to defeat Bob Simcock.
The Path to the Mayoralty
The 2016 local elections marked a pivotal and highly competitive chapter in Southgate's career. Running for both mayor of Hamilton and a city councillor position, she faced off against Andrew King. The mayoral race was exceptionally tight; while the initial election-day margin was nine votes, a judicial recount—a legal process to verify vote totals—narrowed that gap to just six votes. Although she did not win the mayoralty at that time, she was successfully elected as a city councillor representing the East ward.
By the 2019 local elections, Southgate returned to the mayoral race. She secured victory with 33.74% of the vote, achieving a majority of 3,137 votes over Andrew King. A key point of contention during this campaign was King's proposal to rename Hamilton to Kirikiriroa, a move made despite public opinion. Following her victory, Geoff Taylor was appointed as her deputy mayor.

Continued Leadership and Retirement
Southgate's effectiveness in office led to her seeking a second term in the 2022 Hamilton mayoral election, which she successfully won. Her leadership provided stability and continuity for the city's administration through the early 2020s.
On 12 January 2025, Southgate officially confirmed that she would not be seeking a third mayoral term in the upcoming 2025 New Zealand local elections, marking the conclusion of her tenure as the city's chief executive.
