This layer includes the current South Island pastoral leases as at the layer's latest revision date. It excludes pastoral leases that have completed Tenure Review, endowment land, special leases, pastoral occupation licences, pastoral vacant land and special leases. Lease boundaries have been derived from graphical cadastral line work held in LandOnline which in many cases was itself derived from the Lands and Survey Department's hard copy record sheets. The boundaries of many of these original Run Plans, on which these leases were based, were obtained from early Run Plans, circa 1860. As such please note that the boundaries are indicative only.
