The1941 New Zealand census had been postponed due to World War II, so the 1946 electoral redistribution had to take ten years of population growth and movements into account. TheNorth Island gained a further two electorates from theSouth Island due to faster population growth. The abolition of thecountry quota through theElectoral Amendment Act, 1945 reduced the number and increased the size of rural electorates. None of the existing electorates remained unchanged, 27 electorates were abolished, eight former electorates were re-established, and 19 electorates were created for the first time, including North Shore.[4]
The boundaries of the North Shore electorate were last adjusted for the first election held using themixed-member proportional (MMP) voting system in1996, when the number of general electorates decreased from 95 (1993) to 60 (1996), and the electorate expanded to the north into an area previously belonging toEast Coast Bays. No boundary adjustments were undertaken in the subsequent redistributions in 2002, 2007,[5] and 2013/14.[6] The 2025 Boundary Review saw the electorate gainWindsor Park fromEast Coast Bays.[7]
The seat has been contested at every election in New Zealand since1946, and except for a single victory by future Labour Attorney-GeneralMartyn Finlay in its first contest, has been safely held by the National Party ever since.
Members of Parliament elected from party lists in elections where that person also unsuccessfully contested the North Shore electorate. Unless otherwise stated, all MPs terms began and ended at general elections.
