Auckland is New Zealand's largest city, with a population of just under 382,000 within the city boundary and 1.18 million in the greater Auckland area. This represents about one third of the population of the whole country. The city and suburbs cover an area of 60 square kilometres, with many of the suburbs having their own unique character. The city is built on a narrow isthmus between two harbours, the Waitemata to the East and the Manukau to the West. Water sports are a pastime enjoyed by a large number of Aucklanders and the city enjoys the reputation as being known as the 'City of Sails' due the number of yachts which sail in the harbours and the adjoining Hauraki Gulf.
