Wellington was originally designed by Captain William Mein Smith the first Surveyor General for Edward Wakefield's New Zealand Company in 1840. It has served as the nation's capital since 1865, the New Zealand Government and Parliament, the Supreme Court, and most of the public service are based in the city. Architectural sights include the Old Government Buildings—one of the largest wooden buildings in the world—as well as the iconic Beehive, the executive wing of Parliament Buildings. Wellington is also home to several of the largest and oldest cultural institutions in the nation, such as the National Archives, the National Library, the Museum of New Zealand Te Papa Tongarewa, and numerous theatres. It plays host to many artistic and cultural organisations, including the New Zealand Symphony Orchestra and Royal New Zealand Ballet. One of the world's most liveable cities, the 2016 Mercer Quality of Living Survey ranked Wellington 12th in the world, and was first in the world for both liveability and non-pollution by Deutsche Bank, from 2017 to 2018. Wellington's economy is primarily service-based, with an emphasis on finance, business services, and government. It is the centre of New Zealand's film and special effects industries, and increasingly a hub for information technology and innovation, with two public research universities. Wellington is one of New Zealand's chief seaports and serves both domestic and international shipping. The city is served by Wellington International Airport, the third busiest airport in the country. Wellington's transport network includes train and bus lines which reach as far as the Kapiti Coast and the Wairarapa, and ferries connect the city to the South Island.
