The town and surrounding rural area has a population of 3,294 (2001 census), and is the centre of an administrative ward of Manukau which takes in much of the largely rural area to the east of the urban heart of the city.
Clevedon is located on the Wairoa River five kilometres from its estuary and outflow into the Tamaki Strait, an arm of the Hauraki Gulf. It is 14 kilometres from the centre of the city of Manukau, which lies to the northwest. To the south of Clevedon rise the rugged hills of the Hunua Ranges. Several popular beaches are located on the coast close to Clevedon, including Duders Beach and Kawakawa Bay. Between these two beaches lies the Duder Regional Park.
