Christchurch City East was first created for the by the Representation Act 1870, which was passed to increase the number of general electorates to 74 from the 61 that were used at the . The Representation Act 1870 also disestablished some multi-member electorates, and the three-member
City of Christchurch electorate was split up, with one part of it forming the new Christchurch City East electorate. (a young engineer who only recently left
Canterbury College and who would become one of the founding members of the
Institution of Professional Engineers New Zealand), and
Frederick Cooke (a prominent member of the
Socialist Party). Davey was successful. The was contested by Davey (the incumbent), Charles Boxshall (who represented the
opposition, which at that point had not formed into a political party),
James McCombs (who was an
Independent Liberal, i.e. he was not part of a formal party), and Frederick Cooke (who had also contested the previous election standing for the Socialist Party). Davey was re-elected, with McCombs coming second. The
Second Ballot Act 1908 provided for second or
runoff ballots between the top two candidates where the top candidate did not get an absolute majority. As Davey had obtained 55.56% of the votes, a second ballot was not required in Christchurch East. This left three other candidates in the election: Henry Thacker (who had contested the previous election as an Independent Liberal, but with Davey's withdrawal contested as behalf of the Liberal Party), George Duncan Macfarlane (an auctioneer with no prior political experience who stood for the
Reform Party), and Hiram Hunter (who this time contested for the
Social Democratic Party, which was the successor to the original Labour Party). Thacker was successful and succeeded Davey.) and Hiram Hunter (who this time contested for the
Labour Party, which had been founded in 1916). Thacker served for two terms until 1922 and was Mayor of Christchurch until 1923. Thacker was defeated in the by
Tim Armstrong of the
Labour Party. The third candidate was W R Devereux, a land agent who stood for the Reform Party. Armstrong was challenged in by S W Richardson, who was the official candidate for the
United–Reform Coalition in 1935. Armstrong's death triggered the , which was held on 6 February. The by-election was contested by five candidates, including representatives from the Labour Party, the Labour breakaway party
Democratic Labour Party and the National Party. The election was won by the Labour candidate,
Mabel Howard, and started her long parliamentary career, which included her becoming the first female cabinet minister in 1947. Howard was confirmed later in
1943 in the general election, where her majority increased substantially (by over 17 percentage points). Dalziel maintained that she was not yet committed to standing, and only formally confirmed on 19 June that she will contest the mayoralty. She confirmed that she will resign from Parliament, thus triggering a
by-election in the Christchurch East electorate. Dalziel resigned before the official results were announced. The
by-election was since held on 30 November 2013 in the electorate. This was won by Labour's
Poto Williams in a convincing victory despite the view that significant population changes since the
2011 Christchurch earthquake made the allegiance to Labour less certain. Williams held Christchurch East in the against National's sitting list MP
Jo Hayes. Since Tim Armstrong's 1922 election win, the electorate (for as long as it has existed) has been held by Labour. ==Members of Parliament==
