Scenic view of

Christchurch is the largest city in the South Island and the second-largest city by urban area population in New Zealand. Christchurch has an urban population of 407,800, and a metropolitan population of 556,500. It is located in the Canterbury Region, near the centre of the east coast of the South Island, east of the Canterbury Plains. It is located near the southern end of Pegasus Bay, and is bounded to the east by the Pacific Ocean and to the south by the ancient volcanic complex of the Banks Peninsula. The Avon River / Ōtākaro winds through the centre of the city, with a large urban park along its banks. With the exception of the Port Hills, it is a relatively flat city, on an average about 20 m (66 ft) above sea level. Christchurch has a reputation for being an English city, with its architectural identity and nickname the 'Garden City' due to similarities with garden cities in England, but also has a historic Māori heritage. Christchurch has a temperate oceanic climate with moderate rainfall.
