The Nelson Province constituted in 1853 under the New Zealand Constitution Act 1852 and covered the entire upper South Island, including all of the present-day Buller, Kaikoura, Marlborough, Nelson, Tasman as well as the Grey District north of the Grey River and the Hurunui District north of the Hurunui River. It was abolished, along with all other provinces, in 1876.AreaNelson 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.
