South Canterbury has an adequate but not generous rainfall for farming. Successful water races for livestock, drawing on the Ōpihi and Waitaki rivers, were built in the 1880s and 1890s.

Irrigation in South Canterbury began with the Redcliffs scheme on the north bank of the Waitaki. Built in 1934–36 and serving more than 2,000 hectares, it was Canterbury’s first irrigation project. The Levels scheme came slightly later. Construction on the larger Morven–Glenavy scheme began in 1971. By 1978 more than 10,500 hectares were under irrigation. More recently, the Ōpuha project has irrigated more than 13,000 hectares in the Ōpuha and Ōpihi valleys. In 2002 South Canterbury had 11.6% of all the land in New Zealand served by an irrigation system.

Plans to irrigate more land – using water from Lake Tekapo to augment the Ōpihi, and from the Rangitātā – have been entangled in legal and planning difficulties. An agreement between Meridian Energy and Mackenzie Country farmers may see 25,000 hectares in the Mackenzie Country irrigated.

Tenure review

Much high-country farmland is leased from the state. Since 1998 farmers have had the option of buying a portion of their farms, in exchange for land with high conservation value. But environmentalists believe too much land has been sold and not enough conserved through this process, known as tenure review. In 2006 they criticised a deal made for Richmond Station (Lake Tekapo): 64% was sold (including 9 km of lake frontage). And some farmers claim that by restricting high-altitude grazing, tenure review makes farms uneconomic.


South Canterbury has had dairy farms since the late 19th century. Sheep and cropping farms were converted to dairying after the Morven–Glenavy irrigation scheme was completed. This recent demand for dairy farms has affected the land market, changed the patterns of rural life and undermined South Canterbury’s tradition of continuous family ownership.

Farming today

Most South Canterbury farmland is pasture. In the Mackenzie District, 91% of all farmland was grazed in 2012. Even in the Timaru and Waimate districts only 14% and 8% respectively of farmland was used for crops.

In 2012 the region had 1.5 million sheep (4.8% of the national flock), almost 300,000 dairy cattle (4.7%) and more than 140,000 beef cattle (3.8%). Merino wool is processed in Timaru.

Cropping remains important in South Canterbury. In 2012 the region contained:

  • 26% of New Zealand land planted in wheat
  • 20% of the land planted in oats
  • 15% of the land planted in barley.

Potatoes are an important crop in the Willowbridge district, and berry fruit are grown near Waimate and Temuka.

Only in the Mackenzie Country do farmers still graze sheep on extensive leasehold runs – the region’s original style of farming. Tenure review, and irrigation, may see Mackenzie Country farming change.
