Newmarket had a local government just like other suburbs of Auckland at that time. The Borough of Newmarket was constituted on 7 May 1885. Before this date the affairs of the district were administered by the Newmarket Highway District (established 26 December 1868) and the Newmarket Road Board (established 19 March 1883). Newmarket Borough Council was merged into Auckland City Council in 1989, then eventually merged into Auckland Council in 2010. During the time when Newmarket was governing itself, it had its own mayor.
