Record a disturbed mark that has previously been recorded in Landonline as reliable

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 (being the found position of an existing mark determined to be disturbed) 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.

For additional information on disturbed marks, see the topic Disturbed marks in the Cadastral Survey Guidelines.

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 state of the disturbed mark as a 'new' mark because it now lies in a new position defined by the survey.

The original mark may also need to be captured as an adopted mark, if it is relevant to the survey.
