Note: this guideline is issued by the Surveyor-General under section 7(1)(ga) of the Cadastral Survey Act 2002 about the Rules for Cadastral Survey 2010 and is not legally binding.

The following information relates to rules 7.3 and 7.4 and the types of non-boundary marks used in a cadastral survey.

It is essential that the framework of non-boundary marks and boundary points link together. This enables the boundary positions to be correctly reinstated in the future.

Rules 7.3 and 7.4 specify:

  • the attributes and location of marks that make up the network of non-boundary marks, and
  • the proximity of survey network marks to boundary points.

Types of non-boundary marks

Traverse marks

The Rules do not require the surveyor to place or use traverse marks. If such marks are used, they must be recorded in the CSD [r 9.6.2(a)] and meet the same accuracy requirements as PRMs and witness marks [r 3.1].  This is because they are treated as non-boundary marks.
