Ernest Eden George, known as Eden George, was born in New South Wales and came to New Zealand as a young man. He made his career in photography and was active in Auckland and Dunedin, but mainly in Christchurch. Entrepreneurial, combative and confrontational, he entered the political scene. In his early life, he stood at five elections to the New Zealand Parliament, but he came last at every occasion. Surprisingly, he was elected Mayor of Christchurch in 1892 without, unlike all his predecessors, having ever served as a councillor on Christchurch City Council before. He had a most difficult year, was soundly beaten at the next election and told councillors that they "should forget him, as he would forget them". Indeed, in 1906, his was the only photo of all the city's ex mayors that was not on display in the mayor's office.

The Mayor of Christchurch is the head of the municipal government of Christchurch, New Zealand, and presides over the Christchurch City Council. The mayor is directly elected using a First Past the Post electoral system. The current mayor, Phil Mauger, was elected in the 2022 mayoral election. The current deputy mayor is Pauline Cotter.
