The New Zealand general election of 1925 was held 4 November (the Māori vote had taken place the previous day) to elect a total of 80 MPs to the 22nd session of the Parliament of New Zealand. A total number of 678,877 (90.02%) voters turned out to vote. In one seat (Bay of Plenty) there was only one candidate.
In 1922, registration as an elector was made compulsory for all those eligible (except Māori).
After the election both Labour and Liberals held 11 seats. A tie at 4,900 votes each in Lyttelton (between the Labour and Reform candidates) was eventually settled in Labour's favour on 13 March 1926. After winning the 15 April 1926 by-election in Eden, Labour became the official opposition.
^Melville Lyons was elected for the Reform Party, originally the votes were equal (4900), then a recount found for Lyons. But on appeal his election was declared void on 13 March 1926, and the previous holder, James McCombs, was restored as the electorate representative.
