Caversham was a parliamentary electorate in the city of Dunedin in the Otago region of New Zealand, from 1866 to 1908.
Fifteen additional South Island electorates were created, including Caversham, and the number of Members of Parliament was increased by 13 to 70.
Cantrell resigned in the following year, and the subsequent 1872 by-election was won by William Tolmie.
The 20 August 1875 by-election was won by Robert Stout, who contested the City of Dunedin electorate a few months later at the 1875–76.
Thomas Sidey won the 1901 by-election and held the seat until it was abolished in 1908, when he was elected for the Dunedin South electorate instead.
