Abstract: A national assessment of the relative suitability of land for Pinus radiata is presented using site index as the measure of site quality. The physical base for the assessment was the land use capability units of the New Zealand Land Resource Inventory.

The data indicate that 12% of the North Island and 44% of the South Island are unsuited to Pinus radiata while 24%> and 6%o respectively have a site index greater than 29 metres.
