The 1960 election had been won by the National Party, beginning New Zealand's second period of National government. Keith Holyoake, who had briefly been Prime Minister at the end of the first period, returned to office. The elderly leader of the Labour Party, Walter Nash, had agreed to step down following his government's defeat, but disliked the prospect of being succeeded by his Minister of Finance, Arnold Nordmeyer. Nash instead backed first Clarence (Gerry) Skinner and then, after Skinner's death, Fred Hackett. In the end, however, Nordmeyer was victorious. Nordmeyer, however, was unpopular with the general public, being remembered with hostility for the tax hikes in his so-called 'Black Budget'. Labour struggled to overcome this negative perception of its leader, and was only partially successful.
The date for the main 1963 elections was 30 November. 1,345,836 people were registered to vote, and turnout was 89.6%. This turnout was around average for the time. The number of seats being contested was 80, a number which had been fixed since 1902.
The 1963 election saw the governing National Party retain office by a ten-seat margin. It had previously held office by a twelve-seat margin. National won a total of forty-five seats, while the Labour Party won thirty-five. In the popular vote, National won 47.1% to Labour's 43.7%. The Social Credit Party won 7.9% of the vote, but no seats. Four of their candidates also missed the nomination deadline.
