The year 1850 is generally taken as the one in which settlers at Riverton/Aparima definitely changed over from ploughing the sea to ploughing the land. By that time whaling along the Southland coasts gave only a precarious living and the settlers of Riverton saw they would either have to take to the land or move to a more favourable locality. The settlers had their plots of land and as much stock as they could afford. This however immediately raised the question as to who really owned the land. As long as the whalers confined themselves along the Jacobs River estuary, it was not thought worth while to challenge their right to the small area they occupied. With the intricate system of land ownership among the Maori, Captain Howell realised that he was not really the sole owner of those vast tracts of land which he believed were handed over to him at the time of his marriage to Kohi-Kohi. Fortunately the central government found out what was happening and sent Mr W.B.D. Mantell to negotiate with the southern Maori for the purchase of the area known as Murihiku. Walter Baldock Durrant Mantell arrived at Riverton on 27 December 1851, and began negotiations with the various chiefs of Southland. It was not until 17 August 1853 that the area of Murihiku (which encompassed Southland), was purchased from the Maori. The township being surveyed by the New Zealand Government in 1861.
