Culverden is a small town in the northern Canterbury region of New Zealand's South Island. It lies at the centre of the Amuri Plain. Culverden has traditionally been surrounded by sheep farms. Dairy farms have now become more common as a result of irrigation schemes in the area. The Waiau Plains Irrigation Scheme was completed in 1980. It provides irrigation to 17,000 hectares of farmland and the Balmoral Scheme provides irrigation to a further 5500 hectares.

Nelson Province was constituted in 1853 under the New Zealand Constitution Act 1852, and originally covered the entire upper South Island, including all of present-day Buller, Kaikoura, Marlborough, and Tasman districts, along with Nelson City, Grey District north of the Grey River, and the Hurunui District north of the Hurunui River. It was reduced in size by the creation of Marlborough Province in November 1859, then abolished in 1876, along with all the provinces of New Zealand.
