Waitakere was a parliamentary electorate, returning one Member of Parliament to the New Zealand House of Representatives. The electorate was first formed for the and existed until , with breaks from 1969 to 1978 and from 1987 to 1993. The last MP for Waitakere was Paula Bennett of the National Party, who had held this position since the . Population centres The 1941 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. The North Island gained a further two electorates from the South Island due to faster population growth. The abolition of the country quota through the Electoral 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 Waitakere. Waitakere was based around the western suburbs of Auckland. Given the nature of population growth in greater Auckland, and the addition of three new seats in Auckland, the boundaries of Waitakere moved around at every electoral redistribution; in 1999, they were moved northwards as far as Helensville before being pulled back south three years later. In its last boundaries before abolition, the electorate included the Waitakere City suburbs of Henderson, Rānui and Swanson before heading west over the Waitākere Ranges to Piha. Waitakere was first abolished in the 1967 electoral redistribution, which resulted from the Electoral Act 1965 that fixed the number of South Island electorates at 25. As a result, three additional electorates were created in the North Island, and one additional in the South Island. One of those new electorates was , which took over most of Waitakere's area. These changes came into effect with the . Henderson existed for three electoral cycles and was abolished again through the 1977 electoral redistribution, when Waitakere was recreated; this came into effect with the . The 1987 electoral redistribution took the continued population growth in the North Island into account, and two additional general electorates were created, bringing the total number of electorates to 97. In the South Island, the shift of population to Christchurch had continued. Overall, three electorates were newly created, three electorates were recreated, and four electorates were abolished (including Waitakere). All of those electorates were in the North Island.
