The previous electoral redistribution was undertaken in 1875 for the 1875–76 election. In the six years since, New Zealand's European population had increased by 65%. In the 1881 electoral redistribution, the House of Representatives increased the number of European representatives to 91 (up from 84 since the 1875–76 election). The number of Māori electorates was held at four. The House further decided that electorates should not have more than one representative, which led to 35 new electorates being formed, including Dunedin East, and two electorates that had previously been abolished to be recreated. This necessitated a major disruption to existing boundaries.
