In December 1887, the House of Representatives voted to reduce its membership from general electorates from 91 to 70. The 1890 electoral redistribution used the same 1886 census data used for the 1887 electoral redistribution. In addition, three-member electorates were introduced in the four main centres. This resulted in a major restructuring of electorates, and Palmerston was one of four electorates to be first created for the 1890 election. Palmerston North reached its current approximate size at the expense of the old Manawatu electorate in the lead up to the introduction of mixed-member proportional voting in 1996. The boundaries of the Palmerston North electorate were last adjusted in the 2007 redistribution, when the electorate became fully urban and covered all of the urbanised part of Palmerston North City, with the towns in its orbit such as Ashhurst and Linton becoming part of the neighbouring electorate of Rangitīkei. To counter the population loss on the Manawatu River's left bank, the section of the city on the right bank, including the suburb of Milson, was moved in at the same time. No boundary adjustments were undertaken in the subsequent 2013/14 redistribution. At the 2013 census, the Palmerston North electorate reported the highest share of those working in the retail trade industry ; those whose occupation was a community and personal service worker ; and those whose households used mains gas as a heating fuel. Among general electorates, Palmerston North had the second-highest share of those working in the education and training sector, and people affiliated with the Brethren religious denomination.
History
The electorate has been loyal to the Labour Party, not having elected a National MP since 1975, and having not re-elected a National MP since 1966. The first representative of the Palmerston electorate was James Wilson. Wilson previously represented the electorate until its abolition in 1890. In the, Wilson beat Frederick Pirani by 61 votes. In the, Wilson stood successfully in the Otaki electorate and Palmerston was won by Pirani, who was confirmed in and, but defeated in when he contested the electorate. In the 1899 election, Prime MinisterRichard Seddon expressed his opposition to Pirani by endorsing William Thomas Wood, who came second that year. Wood was the successful candidate in the 1902 election, and he was confirmed in. The was held under the Second Ballot Act, contested by three candidates. David Buick, Wood and W. Milverton received 2675, 2626 and 123 votes, respectively. As Buick did not receive an absolute majority, a second ballot was required. Buick standing for the Reform Party was again successful in the second round of voting and was thus elected. Buick was re-elected in and, but died in office on 18 November 1918 during the influenza epidemic. Jimmy Nash, the sitting Mayor of Palmerston North, won the resulting by-election on 19 December 1918. Nash was confirmed at the next five general elections, but was defeated in the by Joe Hodgens of the Labour Party in an election also contested by the then-mayor, Gus Mansford. Hodgens had previously contested the electorate in the and elections. He retired from the electorate at the 1946 election due to the deteriorating health of his wife. The was contested between Ormond Wilson for Labour and Mansford, whose relationship with the National Party was strained, since his 1935 election campaign had contributed to the defeat of Nash. Mansford failed to get nominated by the National Party for the and elections. So in 1946, the National Party decided not to stand a candidate, with Mansford running as an Independent. Wilson obtained a majority of 928 votes. Wilson lost the subsequent election in against Blair Tennent of the National Party. Tennent was confirmed at the subsequent election, but then lost against the Labour candidate, Philip Skoglund, in the. Skoglund contested the against Bill Brown of the National Party and was confirmed by the voters. However, in the, Brown beat Skoglund by the narrow majority of 123 votes. At the, Brown had a 772-vote majority to Skoglund. The was contested by Brown against Labour's Joe Walding, with Brown holding a 259-vote majority. Brown died in office on 16 October 1967 at a function in Kaiapoi. The resulting was contested by five candidates: Walding, Gordon Cruden, John O'Brien, Goldingham and P. J. Wedderspoon. Walding obtained a majority of 592 votes. Walding represented the Palmerston North electorate until the, when he was defeated by John Lithgow, and from to 1981. Six months prior to the, he announced his retirement from Parliament. The Labour nomination was hotly contested and Trevor de Cleene, a good friend of Walding, was the most experienced candidate who put his name forward for selection, and despite concerns about his often controversial nature, he was nominated by the party. The candidate put forward by National was his old foe Brian Elwood, with whom he had worked on the Palmerston North City Council for many years, and against whom he lost the mayoralty contest in 1974. Elwood and de Cleene received 8315 and 10425 votes, respectively, with de Cleene thus entering Parliament in 1981. De Cleene won the, called early by Robert Muldoon, with an increased majority over National's candidate, C G Singleton. In the, de Cleene raised his share of the vote to 56.2%, defeating National's Paul Curry. He did not seek re-election in the. Iain Lees-Galloway was selected by the Labour Party as successor to retiring MP Steve Maharey, who became Vice Chancellor of Massey University, in a contested Labour Party selection for the. Lees-Galloway defeated the National Party candidate, Malcolm Plimmer, with a majority of 1,117 votes. In the, Lees-Galloway was confirmed with an increased majority of 3,285 votes, defeating National's Leonie Hapeta. In the, Lees-Galloway was challenged by the Mayor of Palmerston North, Jono Naylor, but remained successful. Lees-Galloway had a decreased majority of 2,212 votes over Naylor. Naylor was the lowest-ranked National MP who entered Parliament via their list. Ian Lees-Galloway is to retire at the 2020 election and will be replaced by Tangi Utikere, the city's deputy mayor, as Labour candidate.
