The 1943 New Zealand general election was a nationwide vote to determine the shape of the New Zealand Parliament's 27th term. With the onset of World War II, elections were initially postponed, but it was eventually decided to hold a general election in September 1943, around two years after it would normally have occurred. The election saw the governing Labour Party re-elected by a comfortable margin, although the party nevertheless lost considerable ground to the expanding National Party.
