Classification of surveys (sec. 8 (1))

16. (1) This clause applies to surveys the plans relating to which are or

will become recorded plans.
classified as a First, Second or Third Order survey according to whether ) A survey carried out for inclusion in the State Control Survey is
the standards of accuracy achieved in the survey are those specified in the

1993—No. 459

column headed “First Order”, “Second Order” or “Third Order” in Table 1 to this clause. Any such survey that achieves standards of accuracy less than those specified is classified as a Fourth Order survey.

(3) A survey carried out for any other purpose which achieves a standard of accuracy specified in Table 2 to this clause is classified as a survey of the class specified opposite the standard.

(4) For the purpose of classifying surveys in accordance with Table 2:

(a)	in a closed traverse, the ratio of the misclose to the perimeter must not exceed the ratio shown opposite the appropriate class, the misclose being determined as where a is the error in eastings and b is the error in northings; and
(b)	in the lines of levels, the difference between the forward and

backward runs of levels must not exceed where e is the allowance difference per kilometre and km is the total number of kilometres levelled; and

(c) if the standard of accuracy of a survey is between any of the standards specified in the Table, the lower standard determines the class of the survey.

EXPLANATORY NOTE

The purpose of this Regulation is to repeal and remake, with modifications, the Survey Co-ordination Regulations 195 1. The new Regulation makes provision for the following matters:

• the registration by public authorities of surveys carried out by or on behalf of those authorities (and particulars of their related plans) which are the subject of a notice from the Surveyor-General (cl. 4);

• the form in which lists of such surveys and plans are to be sent to the
Surveyor-General (cl. 5);

• the indexing and maintenance of field notes made in respect of such
surveys (cl. 6);

• notice sent to the Surveyor-General by a public authority of its intention to
commence a survey and of its completion of the survey (cll. 7 and 8);

• the prescribed standard datum as to levels and prescribed kinds of
permanent marks that may be placed after a survey (cll. 9 and 10);

• sketch plans showing the location of permanent marks (cl. 11);

• the conventional signs to be used on plans sent to the Surveyor-General
(cl. 12);

• the prescribed standards of measurement and accuracy of surveys carried
out by or on behalf of public authorities (cll. 13 and 14);

• the prescribed form of the central plan register, the classification of surveys recorded in the register and the particulars noted on plans recorded in the register (cll. 15, 16, and 17)

• notice to the Surveyor-General of alterations to recorded plans (cl. 18);

• the standard of accuracy of connections to permanent marks (cl. 19);

• the protection of permanent marks by public authorities and the reporting of irregularities in relation to, or the destruction or disrepair of, permanent marks (cll. 20 and 21);

• notice to the Surveyor-General of the intended removal or alteration of
permanent marks for building reconstruction or similar reasons 23). (cl.

Regulation is made under the Survey Co-ordination Act 1949, including section 22 (the general regulation making power) and various other sections mentioned in the Regulation. This Regulation is made in connection with the staged repeal of subordinate legislation under the Subordinate Legislation Act 1989.
