Nadi (pronounced ˈnandi ; नदी) is the third-largest conurbation in Fiji. It is located on the western side of the main island of Viti Levu, and had a population of 42,284 at the most recent census, in 2007. A 2012 estimate showed that the population had grown to over 50,000. Nadi is multiracial with many of its inhabitants Asians, Indian or Indigenous Fijians, along with a large transient population of foreign tourists. Along with sugar cane production, tourism is a mainstay of the local economy. The Nadi region has Fiji's highest concentration of hotels and motels. With its large Indo-Fijian population, Nadi is a centre for Hinduism and in Fiji. It has the largest Hindu temple in the Southern hemisphere, and is a site for pilgrims called Sri Siva Subramaniya temple. Nadi International Airport, located 9 kilometres from Nadi, is the largest airport in Fiji. Thus, Nadi is the principal port of entry for air travelers to Fiji, even though it is on the opposite (western) side of the island of Viti Levu from the nation's capital and largest city, Suva. During World War II the US Navy built a base at Nadi as part of Naval Base Fiji. Nadi Township was established in 1947. About that time the colonial government of Fiji established offices on the higher grounds of Nadi. A few businesses were then established around the government offices to service them, and other business organisations from other parts of Fiji followed suit. Some concerned citizens of Nadi attempted to move the town centre to Martintar because the existing centre was prone to flooding, but this did not eventuate because the move Nadi Township had already developed strong roots in its existing location. Elective local government was introduced in 1967. Dr A. H. Sahu Khan was the first elected Chairman of the Nadi Township Board. With the introduction of the Local Government Act in 1972, the status of the Board was changed to a Town Council. H. M. Lodhia became the first Mayor of Nadi in 1972 and remained in office until December 1973.
