Rodney was a New Zealand parliamentary electorate, returning one Member of Parliament to the House of Representatives.

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.

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.

[9] Rodney was first created for the 1871 election 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).

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 2011 election, when he stood as a list candidate only.
