- reference to any prior correspondence with LINZ about issues relevant to the application of these rules to the CSD
- notification from the Māori Land Court of a non-standard appellation used
- notification from the Māori Land Court to support a boundary marking exemption
- Certification
A CSD must be certified and dated by the cadastral surveyor as follows…
- “I [name], being a licensed cadastral surveyor, certify that:
- this dataset provided by me and its related survey are accurate, correct, and in accordance with the Cadastral
Survey Act 2002 and the Cadastral Survey Rules 2021; and - the survey was undertaken by me or under my personal direction.”
- this dataset provided by me and its related survey are accurate, correct, and in accordance with the Cadastral
- Units of measure for CSDs
Distance and reduced levels
Bearings
Horizontal distances must be reduced to…
- metres (recorded to sufficient significant figures to reflect the accuracy requirements of these rules)
- sexagesimal degrees, minutes, seconds, clockwise from north (recorded to sufficient significant figures to reflect the accuracy requirements of these rules)
- the ellipsoid / ellipsoidal distance
- Adopted information must match source
All adopted information, including accepted information other than the conversion of units of measure or the application of a bearing adjustment, must be copied from its source without change. The source is… (2)
(general & water/water CL/irregular)
- the CSD that measured or calculated the value
- for a water boundary, water centre-line boundary, or irregular boundary the CSD that measured or defined that boundary.
Subpart 2. Record of survey

A record of survey must include…(7)
(Different to simple boundary reinstatement record of survey)
- dataset description
- statement of certification
- the date on which the survey was completed (if a field measurement has been made)
- list of CSDs used (and land district if CSD number not unique)
- survey diagram
- on every sheet, CSD number, sheet number, total number of sheets
- identity of any parcel to be extinguished
Subpart 2. Record of survey
- Datum information
A record of survey must include what if a bearing is included, and a reduced level is included?
- if a bearing is included, the official projection
- if a reduced level is included, the vertical datum
Subpart 2. Record of survey
- Vector information
A record of survey must include what for each bearing? (4)
(1 x measured vectors, 2 x adopted vectors, 1 x other)
- the source CSD number for each vector, distance, bearing, and arc that has been adopted
- any bearing adjustments applied to each CSD from which a bearing is adopted
- information indicating whether any bearing, distance, or arc has been calculated, measured, or adopted
- for measured vectors, the type of equipment used
Subpart 2. Record of survey
- Boundary information
