21. Alternative methodology for authorised surveys in special cases
(1) An authorised land officer may, by written notice, authorise a departmental surveyor to carry out an authorised survey in a manner different from that required by the Licensed Surveyors (Guidance of Surveyors) Regulations 1961 if the officer is satisfied that ¾
(a) the value of the relevant land does not justify carrying out a survey in the manner required by those regulations;
(b) the nature of the relevant land makes it impracticable to carry out a survey in the manner required by those regulations; or
(c) other special circumstances exist that justify carrying out the survey in a manner different from that required by those regulations.
(2) An authorised land officer may vary or revoke an authorisation under this regulation at any time by giving written notice to the departmental surveyor to whom the authorisation was granted.
