Use of non-NZGD2000 bearings

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 the circumstances where non-NZGD2000 bearings (including old cadastral, NZGD1949 and magnetic bearings) may be used in a CSD.

Magnetic bearings and accepted boundaries

All bearings in a CSD must be in terms of the same orientation with the exception of a survey which is permitted to accept a boundary with a magnetic bearing [r 4.1(d)].  In this case, the magnetic bearing can remain without change [r 8.4].  Note that the magnetic bearing must be identified in the CSD [r 9.6.12].

Bearings for non-primary parcel surveys

Rule 4.1 does not apply in the case of a cadastral survey that only creates non-primary parcels, such as an easement parcel. Bearings can be in terms of the bearings of the underlying parcel boundaries including where they are in terms of Old Cadastral or NZGD 1949 datum. The exception to this is for surveys that create new covenants in terms of rule 16 (Alternative requirements for covenant parcels) or new non-primary parcels in terms of rule 17 (Alternative requirements for non-primary parcels) where the bearings must be in terms of the official projection [r 16.4(a) and r 17.1(d)(ii)].

All bearings must be in the same terms [r 4.1(c)].

Bearings for surveys with no field measurements

Rule 4.1 does not apply in the case of a cadastral survey that has no new field measurements [r 4.1(b)]. Bearings can be in terms of the bearings of the underlying parcel boundaries including where they are in terms of Old Cadastral or NZGD 1949 datum. Examples include surveys which are created from data which is adopted from existing survey records.

All bearings must be in the same terms [r 4.1(c)].

Bearings for boundary marking surveys

Rule 4.1(a) does not apply in the case of a survey which has a purpose of only marking existing boundaries [r 4.1(a), 4.1(b), 11.2(a)], but rule 4.1(c) still applies.
