Provision for onerous leases

LINZ has onerous contract obligations where the unavoidable costs of meeting the contractual obligations exceed the economic benefits expected to be received from it. The provision relates to the lease on 3 The Terrace, Wellington, which expires in 2060.

Huntly East subsidence

The Crown has an obligation to purchase properties affected by mining in the Huntly East area (CAB (97) M 33/7A Refers). The Huntly East Subsidence Policy states that if a property is not sold on the open market within six months, the Crown will buy the property from the vendor at current market value. Until all properties have been purchased by the Crown, this policy will continue. Properties purchased by the Crown are covenanted to protect the Crown from future liability then on-sold (generally at a lower value as a result of the covenant on the title).
