New Zealand supplementary elections

The New Zealand Constitution Act 1852 authorised the General Assembly to establish new electoral districts and to alter the boundaries of, or abolish, existing districts whenever this was deemed necessary. The rapid growth of New Zealand's European population in the early years of representative government (particularly in Otago) meant changes to electoral districts were implemented frequently, both at general elections, and on four occasions as supplementary elections within the lifetime of a parliament.

1859 supplementary election

The Electoral Districts Act 1858 established four new electorates; Marsden and Wairarapa in the North Island, and Cheviot and Wallace in the South Island. Elections were held from 7 November to 18 December 1859 during the term of the 2nd New Zealand Parliament and required redrawing of the electoral boundaries of Bay of Islands, Northern Division, Wairarapa and Hawke's Bay (renamed as County of Hawke), Wairau, Christchurch Country and Dunedin Country electorates.

Elections were held from 28 March to 14 April 1863. All electorates before and after changes returned two members, with each of the previous incumbents in City of Dunedin being assigned an incumbency in one of the Dunedin Suburbs electorates although Thomas Dick resigned before taking up his entitlement in Dunedin and Suburbs North.

1868 Māori election

Main article: First Māori elections

The Maori Representation Act 1867 established four electorates to represent the indigenous Māori population. The European (or General) electorates at the time only enfranchised adult males who were the owners of freehold or leasehold land, and as Māori land was generally communally owned under customary title this put them outside the definitions of the Constitution Act, and unable to register to vote. Elections to the four electorates; Eastern Maori, Northern Maori, Southern Maori and Western Maori were held on or around 15 April 1868.
