The most significant issue in the 1951 elections was the growing industrial unrest of the time, particularly the ongoing dockworkers dispute. Holland condemned the strikers, calling the situation "industrial anarchy". The Labour Party, under Nash, attempted to take a moderate position in the dispute, but ended up displeasing both sides. Holland, seeking a mandate to respond strongly to the strike, called a snap election. Another issue was high inflation, which frustrated voters and without the strike, might have threatened Holland's government.
The date for the main 1951 elections was 1 September, and for the first time, elections to the four Maori seats were held on the same day. The 1951 elections were also the first under the new regulations which required elections to be held on a Saturday. 1,205,762 people were registered to vote, and turnout was 89.1%. The number of seats being contested was 80, a number which had been fixed since 1902.
The 1951 election saw the governing National Party re-elected with a twenty-seat margin, a substantial improvement on the twelve-seat margin it previously held. National won fifty seats compared with the Labour Party's thirty. The popular vote was closer, however, with National winning 54% to Labour's 46%. No seats were won by minor party candidates or by independents. This was the last New Zealand general election in which any party has ever captured a majority of the popular vote.
