The Canterbury Plains (Māori : Kā Pākihi-whakatekateka-a-Waitaha [1] ) are an area in New Zealand centred in the Mid Canterbury, to the south of the city of Christchurch in the Canterbury region. Their northern extremes are at the foot of the Hundalee Hills in the Hurunui District, and in the south they merge into the plains of North Otago beyond the Waitaki River. The smaller Amuri Plain forms a northern extension of the plains.
The Canterbury Plains were formed from Quaternary moraine gravels transported from the Southern Alps and deposited here during glacial periods in the late Pleistocene approximately 3 million to 10,000 years ago. [2] The alluvial gravels were then reworked as shingle fans of several of the larger rivers, notably the Waimakariri, the Rakaia, the Selwyn, and the Rangitata. Part of the Canterbury-Otago tussock grasslands, the land is suitable for moderately intensive livestock farming but is prone to droughts, especially when the prevailing wind is from the northwest. At these times, the weather phenomenon known as the Nor'west arch can be seen across much of the plain.
A major earthquake on 4 September 2010 revealed a previously unknown geological fault beneath the Canterbury Plains and created a surface rift that offset features by as much as four metres in places. [3]
The rivers of the Canterbury Plains have a distinctive braided appearance, which differentiates this area from the plains of North Otago to the south – beyond the Waitaki, the rivers typically have narrower, well-formed channels, rather than spreading across wide shingle depressions, as in Canterbury.
Most of the population of Canterbury lives in a series of large and small towns arranged northeast to southwest along the plains, connected by State Highway 1 and the Main South railway line. These include Christchurch, Ashburton and Timaru, and the smaller Kaiapoi, Dunsandel, Rakaia, Temuka, and Glenavy. Other towns on the plains include Rangiora, Leeston, Lincoln, Darfield, Geraldine, Methven and Waimate.
The extremely rare weevil Hadramphus tuberculatus is endemic to the plains.
Canterbury is a region of New Zealand, located in the central-eastern South Island. The region covers an area of 44,503.88 square kilometres (17,183.04 sq mi), making it the largest region in the country by area. It is home to a population of 694,400.
The South Island is the largest of the three major islands of New Zealand in surface area, the other being the smaller but more populous North Island and sparsely populated Stewart Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, to the south by the Foveaux Strait and Southern Ocean, and to the east by the Pacific Ocean. The South Island covers 150,437 square kilometres (58,084 sq mi), making it the world's 12th-largest island, constituting 56% of New Zealand's land area. At low altitudes, it has an oceanic climate. The major centres are Christchurch, with a metropolitan population of 521,881, and the smaller Dunedin. The economy relies on agriculture, fishing, tourism, and general manufacturing and services.
Otago is a region of New Zealand located in the southern half of the South Island administered by the Otago Regional Council. It has an area of approximately 32,000 square kilometres (12,000 sq mi), making it the country's second largest local government region. Its population was 257,200 in June 2024.
The Waimakariri River is one of the largest rivers in Canterbury, on the eastern coast of New Zealand's South Island. It flows for 151 kilometres (94 mi) in a generally southeastward direction from the Southern Alps across the Canterbury Plains to the Pacific Ocean.
Rakaia is a town sited on the southern banks of the Rakaia River on the Canterbury Plains in New Zealand's South Island, approximately 57 km south of Christchurch on State Highway 1 and the Main South Line. Immediately north of the township are New Zealand's longest road bridge and longest rail bridge, both of which cross the wide shingle beds of the braided river at this point. Both bridges are approximately 1,750 metres (5,740 ft) in length.
The Rakaia River is in the Canterbury Plains in New Zealand's South Island. The Rakaia River is one of the largest braided rivers in New Zealand. The Rakaia River has a mean flow of 203 cubic metres per second (7,200 cu ft/s) and a mean annual seven-day low flow of 87 m3/s (3,100 cu ft/s). In the 1850s, European settlers named it the Cholmondeley River, but this name lapsed into disuse. The name Rakaia comes from Māori "Ō Rakaia", meaning the place where people were arranged by ranks.
The Waimakariri Gorge is located on the Waimakariri River in inland Canterbury in the South Island of New Zealand.
The Rakaia Gorge is located on the Rakaia River in inland Canterbury in New Zealand's South Island.
The Main South Line, sometimes referred to as part of the South Island Main Trunk Railway, is a railway line that runs north and south from Lyttelton in New Zealand through Christchurch and along the east coast of the South Island to Invercargill via Dunedin. It is one of the most important railway lines in New Zealand and was one of the first to be built, with construction commencing in the 1860s. At Christchurch, it connects with the Main North Line to Picton, the other part of the South Island Main Trunk.
Kaitorete Spit is a long finger of land which extends along the coast of Canterbury in the South Island of New Zealand. It runs west from Banks Peninsula for 25 kilometres, and separates the shallow Lake Ellesmere / Te Waihora from the Pacific Ocean. It is technically a continuous barrier beach, though at its western end it tapers to a point less than 100 metres in width which is occasionally breached at high tide. The spit is noted for its isolation and for its pebbly beaches. At its eastern end is the small settlement of Birdlings Flat, and west of its narrowest point is the settlement of Taumutu.
The Canterbury Province was a province of New Zealand from 1853 until the abolition of provincial government in 1876. Its capital was Christchurch.
South Canterbury is the area of the Canterbury Region of the South Island of New Zealand bounded by the Rangitata River in the north and the Waitaki River to the south. The Pacific Ocean and ridge of the Southern Alps form natural boundaries to the east and west respectively. Though the exact boundaries of the region have never been formalised, the term is used for a variety of government agencies and other entities. It is one of four traditional sub-regions of Canterbury, along with Mid Canterbury, North Canterbury, and Christchurch city.
Mid Canterbury is a traditional, semi-official subregion of New Zealand's Canterbury Region extending inland from the Pacific coast to the Southern Alps. It is one of four traditional sub-regions of Canterbury, along with South Canterbury, North Canterbury, and Christchurch City.
Environment Canterbury, frequently abbreviated to ECan, is the promotional name for the Canterbury Regional Council. It is the regional council for Canterbury, the largest region in the South Island of New Zealand. It is part of New Zealand's structure of local government.
Canterbury in New Zealand is the portion of the South Island to the east of the Southern Alps / Kā Tiritiri o te Moana, from the Waiau Uwha River in the north, to the Waitaki River in the south.
The Canterbury–Otago tussock grasslands is an ecoregion of the South Island, New Zealand, part of the wider tussock grasslands of New Zealand.
State Highway 77 is a state highway in New Zealand going through the inland parts of Central and Mid Canterbury between the towns of Ashburton and Darfield via the Rakaia Gorge. It is wholly single carriageway with two one-lane bridges at the Rakaia and Selwyn Rivers. One set of traffic lights is found in Ashburton marking the southern terminus of the highway.
The South Island, with an area of 150,437 km2 (58,084 sq mi), is the largest landmass of New Zealand; it contains about one-quarter of the New Zealand population and is the world's 12th-largest island. It is divided along its length by the Southern Alps, the highest peak of which is Aoraki / Mount Cook at 3,724 metres (12,218 ft), making it 9th-highest island, with the high Kaikōura Ranges to the northeast. There are eighteen peaks of more than 3,000 metres (9,800 ft) in the South Island. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush, and Fox and Franz Josef Glaciers. The dramatic landscape of the South Island has made it a popular location for the production of several films, including The Lord of the Rings trilogy and The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. It lies at similar latitudes to Tasmania, and parts of Patagonia in South America.
The Waitaki Dam is one of eight hydroelectric power stations which form the Waitaki hydroelectric scheme on the Waitaki River in the Canterbury Region of New Zealand. The dam was the first of three to be built on the Waitaki River and was constructed without earthmoving machinery; over half a million cubic metres of material was excavated, almost entirely by pick-and-shovel. The Waitaki Dam's construction was followed by the development of Aviemore Dam and Benmore Dam, and importantly, every dam built in New Zealand since the Waitaki has benefited from lessons learned during its construction.
