This layer provides metadata about cadastral surveys along with reference points indicating the location of the survey.

A cadastral survey determines and describes the spatial extent (including boundaries) of interest of land within New Zealand. Each survey is allocated a unique reference number (that prior to Landonline included reference to the land district.

This data provides details that identify the type of survey, the purpose, description and key dates relating to the survey.

This table provides registered (or current) Record of Title estate data.

A Title estate is a type of ownership of a piece of land e.g. fee simple estate, leasehold estate. Estates are used to link the registered owners to the Record of Title. A Record of Title can have more than one estate and type.

This data enables linking between the title information provided in the NZ Property Titles List and registered ownership information in the NZ Property Titles Owners List. Note: The registered owner dataset a restricted access dataset and requires you to agree to the LINZ Licence for Personal Data.

This table can also be linked to the spatial parcel data using the NZ Title Parcel Association List, although care is necessary when making this relationship (refer to the table metadata).

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 table is used to associate live and part-cancelled Records of Titles to current spatial parcels. There is a many to many relationship between titles and parcels.

This table can be used to link NZ Property Titles List, NZ Property Title Estates List, or NZ Property Title Owners List to spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels

.

The match between live/part-cancelled titles and current parcels is more than 99%.

Note: The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. If you find an link that has a source of 'External' that you believe to be incorrect, please contact us.

For more information about the nature of this association data see the LINZ website.

This layer provides all marks and associated information that have an order of 6 or better.
Cadastral surveys are required to connect to these marks if they are within a specified distance.

A cadastral survey network mark is a node which is (or was) occupied by a physical survey monument that meets accuracy standards suitable for cadastral requirements. i.e. Cadastral Survey Network Marks have a NZGD2000 horizontal coordinate order of 6 or better. The complete definition for these mark orders is defined by the following Standard.
"www.linz.govt.nz/survey-titles/cadastral-surveying..."

When a new cadastral survey network mark is named as part of a cadastral survey dataset (plan) its name consists of a mark type and number that is unique to that survey, followed by the plan number e.g. IS I DP 3456; IS II DP3456.

This layer provides the current Hydro parcel polygons with associated descriptive data.

The combination of this layer with the other land parcels and road parcels equates to the primary parcels layer which provides all current parcels for New Zealand (i.e. excludes historic and pending parcels).

This set of three parcel layers (land, road and hydro) enables easy access to the most common groupings of parcel intents (excluding non primary parcels).

If you require approved or historic 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.

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

This layer provides survey mark information for marks that are not part of a parcel

A non-boundary mark is any survey mark that is not on a boundary point. The points in this dataset represent physical survey monuments usually placed for cadastral requirements. The data set also includes geodetic marks. Non-boundary marks now enter the Landonline system predominately as part of a cadastral survey dataset (plan) and occasionally via the geodetic processes. For Cadastral marks (i.e.the majority) its name consists of a mark type and number (and is unique to that survey), followed by the ‘plan’ number e.g. IS I DP 3456; IS II DP3456.

Note:
Non-boundary marks used to connect cadastral surveys to the geodetic network are those of 6th order (or better) and this subset is available as the NZ Cadastral Survey Network Marks layer.

This dataset extends the Landonline stored data by including the network accuracy which is based upon its assigned Landonline order - refer LINZS25006 (www.linz.govt.nz/about-linz/news-publications-and-...).

The accuracy provided relates to the accuracy of coordinates of the mark and has little relevance to the accuracy of the boundary in relation to other boundaries. For example, if the coordinates of the mark were used to locate it, a user would expect to find the existing mark within the accuracy (distance) stated.

This layer provides all authoritative bearing and distance survey observations which form part of the cadastral survey dataset

Only observations that have been captured in Landonline are available. This includes observations 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 dataset only contains right-line survey observations. A small fraction of the total number of survey observations are defined as arcs and are provided via the Survey Arc Chords layer.

This dataset was first added to LINZ Data Service on 22 Jul 2011.

This layer provides cadastral Survey Capture Areas (SCA).

In conjunction with the implementation of Landonline in each region, LINZ undertook a project to "back-capture" existing parcel boundaries in the main centres of population and land development. It was intended to "back-capture" approximately 70 percent of existing parcels, which equates to about 20 percent of the land area of New Zealand.

The data capture known as "Populate Electronic Parcel" (PEP) was undertaken under contract by EDS.

The areas to be captured known as "Survey Capture Areas" (SCA) were defined in consultation with local LINZ staff, survey practitioners and Local Authorities.

Within the defined SCAs, the dimensions for surveyed right-lined boundaries of current parcels were captured from existing survey plans. In addition, sufficient traverses, boundary ties, and connections to the geodetic control were captured or surveyed to ensure adequate network geometry and strengthen areas where the boundary dimensions are unreliable. This survey network was adjusted to generate modern survey coordinates for all relevant nodes. Where the resulting boundaries comply with the accuracy requirements of the 1998 Survey Regulations, then the adjusted co-ordinates were declared to have SDC (Survey-accurate Digital Cadastre) status.

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.
