Through an amendment in the Electoral Act in 1965, the number of electorates in the South Island was fixed at 25, an increase of one since the 1962 electoral redistribution. It was accepted that through the more rapid population growth in the North Island, the number of its electorates would continue to increase, and to keep proportionality, three new electorates were allowed for in the 1967 electoral redistribution for the next election. In the North Island, five electorates were newly created and one electorate was reconstituted while three electorates were abolished. In the South Island, three electorates were newly created and one electorate was reconstituted while three electorates were abolished. The overall effect of the required changes was highly disruptive to existing electorates, with all but three electorates having their boundaries altered. These changes came into effect with the. Wigram is based around south-western Christchurch. The main suburbs in the seat are Spreydon, Hillmorton, Riccarton, Hornby and Sockburn. Following the 2013/2014 boundary review, it lost the suburb of Somerfield and parts of Hoon Hay to Port Hills. The electorate's name comes from the suburb of Wigram, and by extension the former Wigram Aerodrome, itself named after colonial businessman Sir Henry Wigram. The electorate shifted southwards at the 2020 redistribution, gaining Aidanfield and parts of Hornby South from and, but losing Avonhead to.
History
The electorate had previously existed from 1969 to 1978, when it was held by Mick Connelly for Labour. Wigram was one of the original sixty-five Mixed Member Proportional electorates created ahead of the 1996 election, when the number of South Island seats was reduced to sixteen. The formerly safe Labour seat of Sydenham lies at Wigram's core, and Labour's strong showing in the party vote in both 2002 and 2005, where the party won nearly half of all party votes cast, indicates that Wigram's political inclinations are left-leaning in nature. Its most well-known MP Jim Anderton was himself the Labour MP for Sydenham between 1984 and 1989, before he split from the party over its political directions and formed the NewLabour Party, which later merged into the Alliance; the Alliance disintegrated in 2002, but Anderton, by then the leader of the Progressive Party held off all challengers to easily hold the seat. In the, the seat reverted to Labour candidate Megan Woods after his retirement, but the National Party comfortably won the party vote. The chairman of the Canterbury-Westland branch of the National Party, Roger Bridge, stated in April 2014 that Woods had a low profile and the Wigram electorate was now "winnable". Woods won re-election in the with a more than a doubled majority.
