A tenure review agreement has been reached for the North Canterbury high country station, Island Hills.
Tenure review is a voluntary process that gives pastoral lessees an opportunity to buy some of their leasehold land from the Crown.
The rest of the land, usually areas of high ecological value, returns to full Crown ownership for conservation purposes.
Land Information New Zealand (LINZ) said 1600 hectares would be transferred to the Crown as conservation estate and 3200 will be freehold subject to conservation covenants, that restricts activities such as grazing, vegetation clearance and burning.
The remaining 200 hectares would be freehold without restrictions.
