The Auckland metropolitan area, in the North Island of New Zealand, is the largest and most populous urban area in the country with over 1.4 million residents, 31 percent of the country's population. Demographic trends indicate that it will continue to grow faster than the rest of the country. Increasingly cosmopolitan, Auckland also has the largest Polynesian population of any city in the world, and has seen many people of Asian ethnicity move there in the last two decades. The 2009 Mercer Quality of Living Survey ranked Auckland 4th place in the world on its list. In Māori Auckland's name is Tāmaki-makau-rau, or the transliterated version of Auckland, Ākarana. Auckland lies between the Hauraki Gulf of the Pacific Ocean to the east, the low Hunua Ranges to the south-east, the Manukau Harbour to the south-west, and the Waitakere Ranges and smaller ranges to the west and north-west. The central part of the urban area occupies a narrow isthmus between the Manukau Harbour on the Tasman Sea and the Waitemata Harbour on the Pacific Ocean. It is one of the few cities in the world to have harbours on two separate major bodies of water.

Christchurch is the largest city in the South Island of New Zealand, and the country's second-largest urban area. It is one third the way down the South Island's east coast, just north of Banks Peninsula which itself, since 2006, lies within the formal limits of Christchurch. The city was named by the Canterbury Association, which settled the surrounding province of Canterbury. The name of Christchurch was agreed on at the first meeting of the association on 27 March 1848. It was suggested by John Robert Godley, who had attended Christ Church, Oxford. Some early writers called the town Christ Church, but it was recorded as Christchurch in the minutes of the management committee of the association.

Hamilton (Kirikiriroa in Māori) is the centre of New Zealand's fourth largest urban area, and Hamilton City is the country's seventh largest territorial authority. Hamilton is in the Waikato region of the North Island, approximately 130 km (80 mi) south of Auckland. It sits at a major road and rail nexus in the centre of the Waikato basin, on both banks of the Waikato River.
