This dataset was first added to LINZ Data Service on 22 Feb 2015.

For further information about this dataset, see the Canterbury earthquake information.

Coordinates computed by adding the effects of deep-seated movement to survey points that had authoritative survey-accurate digital cadastre (SDC) coordinates immediately prior to 4 September 2010 (the first Canterbury earthquake). Marks that did not have SDC status at that time are not included in the dataset. Deep-seated movements were evaluated using the NZGD2000 deformation model.

  • The 'nod_id' column is the Landonline node id. This is the unique identifier for the mark.
  • The 'current_name' column is the Landonline mark name.
  • The 'east_mtpleatm2000' and 'north_mtpleatm2000' columns are the east and north coordinates (metres) in terms of the Mt Pleasant 2000 transverse mercator projection. Rounded to the nearest centimetre.
  • The 'coord_order' column is the Landonline coordinate order immediately prior to 4 September 2010.

The estimated absolute uncertainty of these coordinates is 0.09m at the 95% confidence level.

These coordinates are intended for the use of Licensed Cadastral Surveyors when locating boundaries in Christchurch, in accordance with the Rules for Cadastral Survey 2010 and associated guidance, particularly guidance relating to the earthquakes.

This layer provides all linear parcels (e.g. Centreline easements) and their associated descriptive data as a single layer to facilitate their use independently of the all polygon parcels.

NOTE: This layer contains primary and non-primary approved, current or historic linear parcels (see status flag descriptions for more information).

In conjunction with the Parcels, this layer provides the easiest way to create a relationship with associated tables such as Parcel Title Association List, Parcel Statutory Actions List and Survey Affected Parcels List.

This layer contains spatial and non-spatial (without geometry) parcels. The Landonline system which manages the data maintains non-spatial parcels for many different reasons. The non-spatial parcels can only be accessed via WFS or as a full layer file download. No layer clips can be used. The most common reasons for non-spatial parcels are:

  1. Flats and unit survey plans will create non-spatial parcels for referencing property rights. This is because the Landonline system has not yet been designed to support the spatial definition of these plans.

  2. Titles which were not linked to a spatial parcel during the Landonline title conversion project created non-spatial parcel references. As titles are spatially linked many of these non-spatial parcels will be made historic or will be merged with the associated spatial parcel.

Parcels within this layer contain the following status flags:

  • Approved: The definition of a survey-defined parcel that has been processed and authorised as correct in terms of the survey network.

  • Current: A parcels that has been registered or the parcel is made current by a statutory action against a Legalisation plan.

  • Survey Historic: A parcel that has been extinguished from the primary cadastral network but still exists in live Title estates.

  • Historic: A parcel that has been extinguished from the primary cadastral network and no longer exists in live Title estates or has an current recorded statutory action. Typically this happens when a parcel is subdivided or merged, and new titles or actions are registered against the replacing parcels. Note: Only parcel made historic since the beginning of Landonline operations (2002) are included. See this page for the actual dates when Landonline operations started.

The Linear parcels within this layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the Survey Boundary Marks layer which contains accuracies for each parcel node.

The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. For more information see.

A Statutory Action is an action recorded against a parcel that is authorised by a specific Part or Section of an Act.

This table provides information about the current and historic statutory actions as recorded against specific parcels.

Note: Historic actions are only available in this dataset since the beginning of Landonline operations (about 2000). This page on LINZ's historic property databases provides actual dates when Landonline operations started.

This table has direct relationships with and can be linked to spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels.

For more information about this table, other property datasets, and how to relate them to each other, refer to the Property Boundary and Ownership Data Dictionary.

This layer provides the current non primary linear parcels (e.g. Centreline easements) and their associated descriptive data as a single layer to facilitate their use independently of other non primary parcels.

Linear parcels are non-primary parcels that are defined by a line and a description e.g. the width. The most common example is centreline easements (in gross) e.g. Pipeline easements.

If you require approved or historic linear parcels see the All Parcels Layer

This layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the Survey Boundary Marks layer which contains accuracies for each parcel node.

This layer provides the extents of influence that the work to integrate survey information has on the surrounding Cadastre.

All cadastral surveys must be integrated into the Cadastre. As part of this process the new information 'upgrades' the existing information. This is controlled by a mathematical adjustment process using a Least Squares methodology.

The adjustment/Integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extend of the change largely depends upon the size of the new survey, the difference in accuracy between new and old data and the number of linkages to other Surveys.

In general, where the underlying surveys are older or in a rural location the greater the extent of the adjustment.

This table is used to describe the many to many relationship between surveys and parcels. This is a table to link NZ Survey Plans data with spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels.

An affected parcel is a parcel which is affected by the approval of a survey dataset. A parcel may be affected, created or extinguished. For example, a survey can affect extinguish parcels by rendering them historical and at the same time may create new parcels (subdivision). Parcels may be affected by a survey but remain current (definition of an easement etc).

For more information about this table and other tables and layers that make up this dataset refer to the support documentation.

This layer provides all authoritative arc survey observations and is targeted at cadastral surveyors.

Only observations that have been captured in Landonline are available. This includes vectors that were re-captured in the Survey Capture Areas from survey plans lodged prior to Landonline and all survey observations since.

Individual cadastral surveys will commonly re-measure or re-use cadastral lines. Often they will be the same, however as the accuracy capability has increased over time, differences between 'old' and 'new' observations are more likely. Thus all survey observations include the reference to the Survey Plan.

This layer provides the extents of the data incorporated into an adjustment which has been completed as a Wide Area Cadastral Adjustment (WACA). These adjustments are undertaken in areas where there is already substantial survey-accurate data, but there are some inconsistencies in the data resulting from small changes to geodetic control coordinates and/or the progressive submission of additional Cadastral Survey Datasets (CSDs). The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be no more than 10cm, as the WACAs target areas where coordinates already have fairly high spatial accuracy.

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.
