The 1966 New Zealand general election was a nationwide vote to determine the shape of the New Zealand Parliament's 35th term. It saw the governing National Party win a third consecutive term in office. It was also the first time since the 1943 election that a minor party won a seat in Parliament.

The National Party had established its second administration following the 1960 elections, and had been re-elected in the 1963 election. Keith Holyoake remained Prime Minister. The Labour Party experienced a leadership change shortly before the 1966 elections: Arnold Nordmeyer, who was closely associated with an unpopular previous Labour government, was replaced by the younger Norman Kirk. Labour remained disunited, however, with ongoing leadership problems undermining Kirk's position. Disagreement between unionists and non-unionists regarding economic policy also weakened the party.

One significant issue that divided National and Labour in the 1966 elections was the question of New Zealand's participation in the Vietnam War. Under National, New Zealand contributed a small number of troops, which Holyoake strongly defended during the election campaign. Labour, by contrast, made the recall of troops one of its key policies; former Labour leader Walter Nash was a particularly strong critic of the war. Nash believed that Labour's failure to win the election was because of its principled anti-Vietnam war policy, despite voters preferring Labour's economic policy to National's.^[1]

The date for the main 1966 elections was 26 November. 1,409,600 people were registered to vote. Turnout was 86.0%, a number relatively low for the time. The number of seats being contested was 80, a number which had been fixed since 1902. It was, however, the last election in which the number of seats was set at this level.
