This dataset was last updated on LINZ Data Service on 21 May 2016.

This dataset provides information about the position, height, height datum, height accuracy, mark name, mark type, condition and unique four letter identifier for geodetic marks that have an authoritative height in terms of a vertical datum. Heights are in datums defined at www.linz.govt.nz/geodetic/datums-projections-heigh....

All marks will have positions in terms a 3D New Zealand official geodetic datum. The horizontal positions of marks are provided for approximate location purposes only .

This dataset only contains marks that are within the New Zealand mainland and offshore islands. The height data for these marks have been generated using precise levelling from datum tide gauges, or has been acquired by 3rd party sources either as levelling observations or direct heights.

The source data is from Land Information New Zealand's (LINZ) Landonline system where it is used by Land Surveyors. This dataset is updated daily to reflect changes made in the Landonline.

Accuracy

The accuracy of normal-orthometric heights are described by height orders.

For more information see www.linz.govt.nz/geodetic/datums-projections-heigh....

Note the accuracy applies at the time the mark was last surveyed - see the geodetic database for historical information about height coordinates.

This dataset was last updated on LINZ Data Service on 21 May 2016.

This dataset provides information about the survey control network, position, position accuracy, mark name, mark type, condition and unique four letter code for geodetic marks in terms of New Zealand's official geodetic datum, New Zealand Geodetic Datum 2000 (NZGD2000).

The dataset only contains marks that are within the New Zealand mainland and offshore islands. These positions have been generated using geodetic observations such as precise differential GPS or electronic distance and theodolite angle measurements. The positions are either 2D or 3D depending of the availability of this measurement data.

The source data is from Land Information New Zealand's (LINZ) Landonline system where it is used by Land Surveyors. This dataset is updated daily to reflect changes made in the Landonline.

The mark network is segmented into six control networks which provide control marks for specific purposes. The control_network field within this layer records this network with the 3 or 4 letter abbreviation code as follows:

NRF  - National Reference Frame  
NDMN - National Deformation Monitoring Network  
RDMN - Regional Deformation Monitoring Network  
LDMN - Local Deformation Monitoring Network  
CHN  - Cadastral Horizontal Control Network  
CVN  - Cadastral Vertical Control Network  
BGN  - Basic Geospatial Network  
NHN  - National Height Network

Note a geodetic mark can be in more than network. Also not all geodetic marks are currently associated with a geodetic network. Those that are may be referred to as a control mark. For more information about the control networks refer to www.linz.govt.nz/geodetic/geodetic-programme/surve....

Accuracy

Geodetic marks with a coordinate order of 5 or less have been positioned in terms of NZGD2000. Lower order marks (order 6 and greater) are derived from cadastral surveys, lower accuracy measurement techniques or inaccurate historical datum transformations, and may be significantly less accurate.

The accuracy of NZGD2000 coordinates is described by a series of 'orders' classifications. Positions in terms of NZGD2000 are described by three-dimensional coordinates (latitude, longitude, ellipsoidal height). The accuracy of a survey mark is indicated by its order. Orders are classifications based on the quality of the coordinate in relation to the datum and in relation to other surrounding marks. For more information see www.linz.govt.nz/geodetic/datums-projections-heigh...

Note that the accuracy applies at the time the mark was last surveyed. Refer to the web geodetic database for historical information about mark coordinates.

Note also that the existence of a mark in this dataset does not imply that there is currently a physical mark in the ground - the dataset includes destroyed or lost historical marks. The geodetic database provides more information on the mark status, valid at last time it was visited by LINZ or a maintenance contractor.

This layer identifies critical survey marks which LINZ requires to be physically protected.

Thousands of vital survey marks exist in New Zealand. Many of them are below or at ground level and not noticed by most of us.

People involved in construction work are responsible for making sure survey marks are not damaged. When building works have the potential to destroy existing cadastral and geodetic marks, LINZ needs to be notified so that it can assess whether the marks should be reinstated or replaced. Find out more about looking after the national survey network

Please note there may be other important survey marks not identified on this layer, and that LINZ recommends consultation with a Licensed Cadastral surveyor before any construction or earthworks begin.

If you notice a damaged survey mark, you can report it to LINZ by filling out a form on this website

This dataset was last updated on LINZ Data Service on 21 May 2016.

This layer provides title information (excluding ownership) where there is a data link to one or more primary parcels.

A title is a record of all estates, encumbrances and easements that affect a piece of land. These are now known as Computer Registers incorporating Computer Freehold Registers, Composite Computer Registers, Computer Unit Title Registers and Computer Interest Registers.

This data set removes all ownership fields so that it can be freely distributed. If ownership information is required, the Title & Owners layer and Owners layer; enables this via more restrictive licensing.

An object has been constructed using the parcel shapes where a data link exists. However there can be multiple parcels associated with a title, and a title may only have a part share in a parcel. The constructed shape representing the title will therefore be an aggregation of all parcels that the title is associated with. The ‘spatial extents shared’ attribute when equal to ‘false’ will indicate that title has exclusive interest over all of the shape (this will be case for the vast majority).

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 the current primary parcel polygons and some associated descriptive data that details the appellation (legal description), purpose, size and a list of titles that have an interest in the parcel.

A primary parcel is a portion of land that is intended to be :
• owned by the Crown, except moveable marginal strips
• Held in fee simple ((predominately private ownership)
• Maori freehold land or Maori customary land
• Public foreshore and seabed
• The bed of a lake or river
• Road or Railway
• Vested in a local authority

Primary parcels can be thought of as the 'base level' of the 'jigsaw puzzle' of all land making up New Zealand. Other 'levels' are NZ Non-primary parcels that essentially limit the full rights that would normally be associated with a primary parcel for example easements, covenants, leases and moveable marginal strips etc.

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 combination of this layer with the non-primary parcels layer provides all current parcels for New Zealand (i.e. excludes Historic and Pending parcels)

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 the current land parcel polygons with associated descriptive data and is provided for users that require a separation of road parcels and hydro parcels and thereby require the balance layer (i.e. the remaining primary parcels).

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

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 set of three parcel layers ('road', 'hydro' and 'land') tables easy access to the most common groupings of parcel intents.

This dataset was last updated on LINZ Data Service on 21 May 2016.

This layer provides all cadastral parcel polygons and some associated descriptive data that details the appellation (legal description), purpose, size and a list of titles that have an interest in the parcel.

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 Linear 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.

Polygons within this layer have 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.
