# Waikato (New Zealand electorate)

Waikato is an electorate in the New Zealand Parliament. A Waikato electorate was first created in 1871 and an electorate by this name has existed from 1871 to 1963, 1969 to 1996, and 2008 to the present, though exact borders have often changed.
The Waikato electorate is represented by Tim van de Molen for the National Party, who has held the seat since the 2017 general election.

## Geography

The Waikato electorate, whose borders were last altered in 2020, is in the Waikato region and includes largely rural areas to the north and the west of the city of Hamilton. The Waikato River flows along near its southern boundary then travels north through the electorate. It includes small portions of the outskirts of Hamilton and Cambridge. Towns within the electorate include Morrinsville, Huntly, and Matamata, each of which have populations around 8,000.
In a piece for the 2020 election, journalist Tom Rowland described the area as "one of the country's most vital regions, home to farmers and agricultural industries that continue to hold New Zealand's economy steady in the wake of the Covid-19 pandemic". Rowland considered it to be a key area for future economic development, calling it "the key to activating the Golden Triangle between Auckland, Hamilton and Tauranga." He also noted that it was the birthplace of both Jacinda Ardern and Judith Collins, the Prime Minister and the Leader of the Opposition, respectively, at the 2020 election.

## History
### Creation and seat holders prior to 1938

The Waikato electorate was first contested in the 1871 election. James McPherson was elected, but he resigned the same year, on 20 December. William Jackson won the resulting 1872 by-election. Jackson retired at the end of the parliamentary term in 1875. Frederick Whitaker won 5 January 1876 election. In the 1879 election, Whitaker contested the Eden electorate but was beaten by Joseph Tole.
The Waikato electorate was won by John Blair Whyte in the 1879 election, who served for eleven years until 1890 when he retired. Whyte was appointed to the Legislative Council in the following year. John Bryce, who first became Member of the House of Representatives during the 4th Parliament, succeeded Whyte in the 1890 election, but he resigned in the following year. The resulting 1891 by-election was won by Edward Lake, who retired at the end of the parliamentary term in 1893.
The 1893 election was won by Alfred Cadman for the Liberal Party, who had been an MP in various electorates since 1881. At the next election in 1896, Cadman successfully contested the Ohinemuri electorate. The Waikato electorate was won by Frederic Lang in 1896, who represented the electorate until his defeat by the Liberal Party's Henry Greenslade in the 1905 election. Greenslade held the electorate until 1911, when he was defeated by the Reform candidate Alexander Young.
Young won subsequent elections in 1914 and 1919. In the 1922 election, he successfully contested the newly formed Hamilton electorate. Young was succeeded by the Liberal candidate Frederick Lye in the Waikato electorate in 1922. At the 1925 election, Lye was defeated by Reform's Daniel Stewart Reid. Lye in turn defeated Reid at the 1928 election, but this time standing for the United Party. The United–Reform Coalition was established just before the 1931 election and Lye was again successful. In the 1935 election, Lye was beaten by Robert Coulter of the Labour Party. Coulter served only one term in Waikato, as he was defeated by the National Party candidate Stan Goosman in the 1938 election.

### 1938 onward

Since 1938, the Waikato electorate (when it has existed) has always been held by a National Party member. This trend has lasted through 2020, when the seat was retained by National MP Tim van de Molen. Other electorates which covered parts of this region have also strongly supported National. The electorates of Piako, Matamata, and Karapiro were entirely National-held during their time as electorates, the Hamilton electorate was held by National from 1943 until it was dissolved in 1969, and the Waipa electorate was held by National from 1954 until its dissolution in 1996.
Goosman, who had taken Waikato in 1938, also won the 1943 election, but successfully contested the 1946 election in the newly formed Piako electorate. Goosman was succeeded in Waikato by Geoffrey Sim in 1946. Sim held the electorate until it was abolished in 1963, when he contested Piako instead.
The Waikato electorate was re-established in 1969 following the Electoral Act of 1965, which led to substantial changes in the number, shape, and size of electorates across the country. These changes came into effect with the 1969 election. The first representative was National's Lance Adams-Schneider, who had previously represented the Hamilton electorate. Adams-Schneider retired from Parliament in 1981 and became Ambassador of New Zealand to the United States in the following year. Adams-Schneider was succeeded by National's Simon Upton, who won the 1981 election and started his long parliamentary career with one term in Waikato. Upton contested the Raglan in the 1984 election and was succeeded by National's Rob Storey in Waikato. Storey held the electorate until it was abolished again in the electorate changes that came with the introduction of Mixed-member proportional voting in 1996.
The Waikato electorate was re-established in 2006 for the 2008 election.
Lindsay Tisch, who had been the MP for Piako since 2002, won Waikato at the 2008 election. Tisch retained his seat in the 2011 election and the 2014 election, but he announced he would not stand for the 2017 general election. The seat was won by Tim van de Molen, retaining it for the National Party, who won it again in 2020.
The most recent boundary changes to Waikato occurred in 2020, when more area was added in its north and its south, as well as areas just outside Hamilton and Cambridge.
Three of the five National Party members of parliament for Waikato were cabinet ministers.
