It might if the size of the land has changed. If there has been a change in the actual size of your property due to a landslide or other event, then your land may have to be re-surveyed. If there has been a change in the ground level of your property, this may not change the size even if there has been a change in the height of your land. For more information go to www.linz.govt.nz.
If your property size has been made smaller by a landslip or a flood, you may be able to claim from Toka Tū Ake EQC for the cost of repair of your damaged land or the market value of your lost or destroyed land which is capped at the land value prior to the damage (see: “EQC and Insurance”).
