Hauraki is a former New Zealand parliamentary electorate, from 1928 to 1987 and 1993 to 1996. In the 1987 general election it was renamed Coromandel, the name that had been used from 1972 to 1981. In 1993 it reverted to Hauraki, but became Coromandel again for the first MMP election in 1996.
In the 1927 electoral redistribution, the North Island gained a further electorate from the South Island due to faster population growth. Five electorates were abolished, two former electorates were re-established, and three electorates, including Hauraki, were created for the first time. These changes came into effect with the 1928 election. In its original form, the electorate extended up the coast to Auckland. Settlements that fell into the Hauraki electorate were Howick, Papatoetoe, Mangere, Manurewa, Brookby, Meremere, Miranda, and Waitakaruru. In the 1937 electoral redistribution, the Hauraki electorate moved significantly south, losing all the South Auckland suburbs to the new Otahuhu electorate, and gaining Morrinsville.
In the 1946 electoral redistribution, the Hauraki electorate moved to the north-east, losing Morrinsville again, but gaining Paeroa and most of the Coromandel Peninsula, including Thames, Whitianga, and Coromandel township.
