Rodney (New Zealand electorate)

Rodney was a New Zealand parliamentary electorate, returning one Member of Parliament to the House of Representatives. The last MP for Rodney was Mark Mitchell of the National Party. He held this position from 2011 until the electorate was replaced with Whangaparāoa in 2020. Mitchell stood for and won that seat.

Population centres
The 1941 New Zealand census had been postponed due to World War II, so the 1946 electoral redistribution had to take ten years of population growth and movements into account. The North Island gained a further two electorates from the South Island due to faster population growth. The abolition of the country quota through the Electoral Amendment Act, 1945 reduced the number and increased the size of rural electorates. None of the existing electorates remained unchanged, 27 electorates were abolished, 19 electorates were created for the first time, and eight former electorates were re-established, including Rodney.

The 1981 census had shown that the North Island had experienced further population growth, and three additional general seats were created through the 1983 electoral redistribution, bringing the total number of electorates to 95. The South Island had, for the first time, experienced a population loss, but its number of general electorates was fixed at 25 since the 1967 electoral redistribution. More of the South Island population was moving to Christchurch, and two electorates were abolished, while two electorates were recreated. In the North Island, six electorates were newly created, three electorates were recreated (including Rodney), and six electorates were abolished.

The 1987 electoral redistribution took the continued population growth in the North Island into account, and two additional general electorates were created, bringing the total number of electorates to 97. In the South Island, the shift of population to Christchurch had continued. Overall, three electorates were newly created, three electorates were recreated, and four electorates were abolished (including Rodney). All of those electorates were in the North Island. Changes in the South Island were restricted to boundary changes. These changes came into effect with the.

Rodney covers an area of the northern Auckland region from Warkworth in the north, south through the Hibiscus Coast to Auckland's northern urban fringe. High population growth in north and west Auckland has led to Rodney shrinking – Helensville and Kumeū were taken out in 1999, and the next major town to be removed was Wellsford after the 2006 census.

At the 2020 general election, Rodney was abolished, with the northern section around Warkworth being merged with most of Helensville into Kaipara ki Mahurangi, and the southern section becoming the bulk of the new Whangaparāoa electorate.

History
Rodney was first created for the and was represented by four MPs from 1871 to 1890: Harry Farnall 1871–1872 (resigned); John Sheehan 1872–1879 (elected for Thames in 1879); Seymour Thorne George 1879–1884 (retired); and William Pollock Moat 1884–1890 (retired).

Its first recreation was from the to 1978, and was recreated for a single term six years later for the.

Rodney was again recreated ahead of the change to mixed-member proportional (MMP) voting in 1996. Its original incarnation was coterminous with the district for which it is named – most of the old Albany seat minus its eponymous town, with a large section of Kaipara tacked onto the northern fringe. Both of these seats were held by National MPs – Lockwood Smith in Kaipara and then Deputy Prime Minister Don McKinnon in Albany. Smith won his party's nomination for what is a safe National seat and has held it until the, when he stood as a list candidate only. In the 1996 election, Mike Lee came second standing as an Independent.
