Auckland is the largest city in New Zealand in a Metro area of over one million people. Positioned between the Pacific Ocean and the Tasman Sea the city has become known as the "City of Sails" because of the large number of pleasure craft. The Annual Auckland Regatta is one of the largest one day events of its kind in the world. The city is a magnet for New Zealanders and Pacific Islanders although 75% of the people are of British origin. Actually, the Auckland Urban Area is home to about a third of all New Zealanders.
