Changing to the New Orders

The Rules for Cadastral Survey 2010 that came into effect on 24 May 2010 have different accuracy requirements to their predecessor Surveyor-General’s Rules for Cadastral Survey 2002/2.

The Orders of control marks have been updated to reflect the accuracy definitions in the LINZS25005 and LINZS25006 standards.

The Orders of normal-orthometric heights have been updated to reflect the accuracy definitions in the LINZS25005 and LINZS25006 standards.

On 8 May 2010 LINZ reclassified the Order of all 5a control marks from Order 5 to Order 6.
