Location of the Canterbury Plains
The 'Canterbury Plains' cover an area bounded by the foothills of the
Southern Alps and the east coast of the
South Island of
New Zealand. They are centred 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 Canterbury Plains are formed from the
alluvial shingle fans of several larger rivers, notably the
Waimakariri, the
Rakaia, the
Selwyn, and the
Rangitata. 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.
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 town of the plains include
Rangiora,
Leeston,
Lincoln,
Darfield,
Geraldine,
Methven and
Waimate.
