New Zealand’s chief metropolis enjoys the distinction of having the largest Polynesian community of any city in the world. And its 1.4 million citizens comprise 31 percent of the country’s entire population. The center of the city occupies an isthmus, just over a mile wide at its narrowest point, between Manukau Harbour on the Tasman Sea and Waitemata Harbour on the Pacific Ocean — one of the few major cities to have harbors on two significant bodies of water. Bridges span parts of both harbors, notably the Auckland Harbour Bridge, crossing Waitemata Harbour west of the Central Business District. Auckland is popularly known as the “City of Sails.” Its citizens own around 135,000 yachts and launches, more per capita than any other city in the world. Westhaven Marina is the largest in the entire Southern Hemisphere.
