Bruce was a rural parliamentary electorate in the Otago region of New Zealand, from 1861 to 1922. For part of the 1860s with the influx to Otago of gold-miners it was a multi-member constituency with two members.
In 1865 the Bruce electorate included Tokomairiro, Waihola, East Taieri, suburbs of Dunedin, Inch Clutha, Lawrence, Warepa and Pomahaka.
The Bruce electorate was formed in the 1860 electoral redistribution. It covered the rural area surrounding Dunedin that had previously been part of the Dunedin Country electorate. The Bruce electorate was a two-member constituency.
Charles Kettle and Thomas Gillies were the only two candidates for the newly constituted two-member electorate of Bruce. They were thus declared elected unopposed on 11 February 1861.
Kettle died on 5 June 1862.Edward Cargill succeeded him in the 1862 by-election.
Thomas Gillies resigned and the subsequent by-election was contested by William John Dyer and Arthur John Burns. On 8 April 1865, Burns and Dyer received 102 and 78 votes. Burns was thus declared elected.
Later in 1865, Edward Cargill resigned. The resulting second by-election in 1865, held on 26 July, was contested by James Macandrew and John Cargill. Macandrew and J. Cargill received 207 and 34 votes, and Macandrew was declared elected.
