3 Accuracy standards

3.1

Accuracy of non-boundary survey marks

The accuracy requirements for non-boundary marks on a survey are set out in Table 1.

Table 1: Accuracy requirements for non-boundary marks on a survey
The horizontal and vertical accuracy between…must not exceeda
(a)all new and old non-boundary marks …√[0.0252 + (dist × 0.0001)2] m, at the 95 % confidence level
(b)any two new non-boundary marks, old non-boundary marks, or adopted cadastral survey network marks.0.03 m + dist × 0.00015 m
(c)any two new or old non-boundary marks …0.50 m
a Where dist is the horizontal distance between the points in metres in the case of horizontal accuracy, and the vertical distance between the points in the case of vertical accuracy.

3.2

Accuracy class of boundaries

3.2.1

Class A

Class A accuracies:

(a)

must be used for a boundary and its associated boundary points that are:

(i)

in an urban area, or

(ii)

are intended as a result of a survey to be in an urban area;

(b)

must be used for the boundary and the associated boundary points of any parcel that is not in an urban area, but is used, or is intended as a result of a survey to be used, for intensive commercial, industrial, or residential purposes; and

(c)

may be used in any other circumstances.

3.2.2

Class B

Class B accuracies must be used for a boundary and its associated boundary points except where:

(a)

rule 3.2.1 requires class A to be used, or

(b)

class C or class D is used in accordance with rules 3.2.3 and 3.2.4.

3.2.3

Class C1

Class C accuracies may be used for:

(a)

a primary parcel boundary and its associated boundary points that are defined by adoption where this boundary is either:

(i)

part of a new parcel over 20 ha that comprises more than 80 % of the existing primary parcel being extinguished, or

(ii)

part of a new parcel over 100 ha,

and

(iii)

its boundary points do not meet class B accuracy tolerances in rule 3.3.1(a)(iv), or

(iv)

it is part of a title that is to remain limited as to parcels or remain a Hawke’s Bay interim title, or

(v)

it is a water boundary or an irregular boundary;

or

(b)

a non-primary parcel boundary and its associated boundary points where this boundary intersects or coincides with a primary parcel boundary that is defined by adoption and which meets the criteria in (a);

(c)

any other boundary, with the approval of the Surveyor-General.

3.2.4

Class D2

(a)

Class D must be used for a boundary or boundary point that has been accepted in terms of rule 6.3.

(b)

Class D accuracies may be used for a non-primary parcel boundary and its associated boundary points where this boundary intersects or coincides with a primary parcel boundary that meets the criteria for an accepted boundary in rule 6.3

3.2.5

Class of boundaries and boundary points

(a)

The accuracy class that applies to a boundary point must be the highest class of the boundaries connected to that point.

(b)

A boundary or boundary point defined by survey must be either class A or class B, unless otherwise approved by the Surveyor-General.

3.3

Accuracy of right-line boundaries and arc boundaries

3.3.1

Accuracy of boundary points3

(a)

The accuracy requirements for each class of boundary point on parcels created on the survey are set out in Table 2.

Table 2: Accuracy requirements for boundary points on a survey
Boundary classThe horizontal and vertical accuracy between...must not exceeda...
(i)Aall boundary points, other than adopted points, and irrespective of these points being marked or not…√[0.042 + (dist × 0.0001)2] m at the 95 % confidence level
(ii)Aany boundary point and any other boundary point, including adopted points and irrespective of these points being marked or not…0.06 m + dist × 0.00015 m
(iii)Ball boundary points, other than adopted points, and irrespective of these points being marked or not…√[0.202 + (dist × 0.0004)2] m at the 95 % confidence level
(iv)Bany boundary point and any other boundary point, including adopted points and irrespective of these points being marked or not…0.30 m + dist × 0.0006 m
(v)Call boundary points, other than adopted points, and irrespective of these points being marked or not…√[0.602 + (dist × 0.002)2] m, at the 95 % confidence level
(vi)Cany boundary point and any other boundary point, including adopted points and irrespective of these points being marked or not…1.00 m + dist × 0.003 m
(vii)Dnot specified
aWhere dist is the horizontal distance between the points in metres in the case of horizontal accuracy, and the vertical distance between the points in the case of vertical accuracy.
(b)

Where any two boundary points in (a) have different applicable accuracy classes, the lower class of boundary accuracy applies between those two points.

(c)

The accuracy standards in (a) also apply between the boundary points of a non-primary parcel and the boundary points of its underlying parcel where that underlying parcel is not created by the survey.4

3.3.2

Accuracy sufficient to avoid overlap

Irrespective of rule 3.3.1, the relationship between a new boundary and any other boundary, including a boundary that is accepted or defined by adoption, must be determined to a sufficient level of accuracy to address the risk of incompatible rights overlapping.

3.4

Accuracy of water boundaries and irregular boundaries

(a)

The position of a water boundary or an irregular boundary, including a boundary defined by adoption, must be determined to a sufficient level of accuracy to take into account:

(i)

the risk of overlap or ambiguity in boundaries, including the water boundary on the other side of the water body,

(ii)

any statutory requirement applying to the width or size of the related water bodies,

(iii)

the potential for the margin of the water body to move and for the related water boundary to move or become permanent as a result of that movement,

(iv)

the nature of the physical feature that defines the boundary, and

(v)

the value of the land and the intensity of the land use.

(b)

Rule 3.4(a) does not apply to water and irregular boundaries accepted under rule 6.3.

3.5

Accuracy of permanent structure boundary witnessing5

(a)

Every boundary point on a permanent structure boundary that is permitted by rules 6.9(b)(iii) to (v) to be non-coincident with the permanent structure must be witnessed by a clearly identified point on the structure.

(b)

The relationship between a boundary point and the witness point described in (a) must comply with the accuracy specified in rule 3.6.

(c)

If a permanent structure boundary and any other boundary are:

(i)

within 1 m of each other when both boundaries are class A, or

(ii)

within 3 m of each other in other cases,

then the accuracy between the boundary points of both boundaries must comply with the applicable accuracy standards in rule 3.3.

3.6

Accuracy of boundary witnessing

The horizontal and vertical accuracy between a boundary point required to be witnessed by rule 7.3.1 and all old and new non-boundary marks within the distances specified in rule 7.3.2(a) or (b) as applicable must not exceed the tolerances specified in Table 3.

B0.20
C0.60
Dnot applicable

3.7

Vector accuracy

A vector must meet the accuracy standards applicable between its end points.
