Overview
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.
Area
Nelson Province initially covered the entire upper South Island. The Marlborough Province split away from the Nelson Province on 1 November 1859 because the majority of the income of the Provincial Council came from land sales in the Marlborough region, but the funds were mostly used in the Nelson region. Land sales in Nelson and Marlborough netted the Nelson Provincial Council £33,000 and £160,000, respectively. Of that, £200 were expended benefiting the Marlborough region. There was considerable conflict between Superintendent John Perry Robinson's policies of supporting smaller land holders, and the objectives of the large pastoral run-holders in the Wairau Valley. The New Provinces Act 1858 allowed for parts of a province to break away if the area was large enough, and enough voters supported such a move. The petition was signed by almost all settlers in the Wairau; only six withholding their support for a split. The new Marlborough Province was gazetted on 4 October 1859.
For perspective, the Marlborough Province took with it the areas of Nelson Province that would later form five administrative areas when the provinces were dissolved in 1876: Blenheim Borough, covering ; Picton Borough, covering ; Kaikoura County, covering ; and Marlborough County, covering , which includes the former Sounds County, the area immediately surrounding the borough of Picton, which amalgamated with Marlborough County prior to 1913 due to insufficient population to ever form its own county council.
