Record a disturbed mark

Use this process to record details of a disturbed mark that has previously been recorded in Landonline as reliable.


This process records details of a disturbed mark that has previously been recorded in Landonline as reliable. This mark physically exists but is not in its original position as defined by previous surveys.

The mark is not disturbed if its change in position is due to fault zone movement or due to Canterbury earthquake movement (Cadastral Survey Rules 2021 rule 108).

What to do

  1. In the Marks panel, record the disturbed mark as a new mark because it now lies in a new position defined by the e-survey.
    • Review the Name field to make sure this mark has a new mark reference. You may have already created the mark reference in the Vector panel.
