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.

**Please read:** This dataset provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist. For this dataset (as opposed to the [NZ Roads Subsections (Addressing)](https://data.linz.govt.nz/layer/53383) dataset, individual road section geometries have been aggregated to a single road centreline geometry where those subsections share the same name, and are generally contiguous. Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation. This dataset has been simplified from LINZ’s NZ Roads dataset, a centralised database for the management of national road data. The comprehensive [set of NZ Roads tables](https://data.linz.govt.nz/set/4788) is also available. These road centrelines do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal. This dataset contains the core attributes of a road to support simple searching or provide a road name context for cadastral data views. Please refer to the [NZ Roads Data Dictionary](https://data.linz.govt.nz/document/12628) for detailed metadata and information about this dataset. --- **APIs and web services** This dataset is available via ArcGIS Online and ArcGIS REST services, as well as our standard APIs.

**Please read:** This layer provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist. A linear geometry in this layer will consist of the individual road section geometries (as opposed to the [NZ Roads (Addressing)](https://data.linz.govt.nz/layer/3382) layer where these have been aggregated). This layer has been simplified from LINZ’s NZ Roads database, a centralised database for the management of national road data. The comprehensive [set of NZ Roads tables](https://data.linz.govt.nz/set/88) is also available. These road centrelines do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal. Some road sections have multiple names; in these cases the non-primary road names are held in additional columns against each road section. This layer contains the core attributes of a road section to support simple searching with locality and territorial authority or provide a road name context for cadastral data views. This layer is a replacement for the NZ [Road Centre Line Subsections (Electoral)](https://data.linz.govt.nz/layer/793) layer. The Electoral road and address datasets will be available until May 2017 to allow users further time to transition. Please refer to the [NZ Roads Data Dictionary](https://data.linz.govt.nz/document/1628) for detailed metadata and information about this layer.

**Please read:** This is the Address Range Road table and is part of the [set of NZ Roads tables](https://data.linz.govt.nz/set/88). The Address Range Road table provides an identifier that groups one or more Road Sections that have a non-standard address range. This currently includes roads that consist of multiple address ranges. The address range values are not held or provided as part of this dataset. The NZ Roads dataset includes eight data tables and eleven lookup tables. The dataset has been sourced from LINZ’s NZ Roads database, a database for the management of national roads, including those managed for addressing purposes. This set of normalised tables replaces the Landonline: Road Centre Line layer and the Landonline: Road Name and Landonline: Road Name Association tables currently published on LDS. These centrelines are required to indicate the presence of an authoritative road name. Named centrelines are not intended to represent the exact location of a road formation. Named centrelines do not indicate the presence of legal access. For a simplified version of the data contained within these tables see [NZ Roads (Addressing)](https://data.linz.govt.nz/layer/3382), which aggregates geometries based on road name, and [NZ Roads Subsections (Addressing)](https://data.linz.govt.nz/layer/3383), which holds the individual geometries. Please refer to the [NZ Roads Data Dictionary](https://data.linz.govt.nz/document/1628) for detailed metadata and information about this layer.

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](http://data.linz.govt.nz/layer/772) and [non-primary](http://data.linz.govt.nz/layer/782) approved, current or historic linear parcels (see status flag descriptions for more information). In conjunction with the [Linear Parcels](http://data.linz.govt.nz/layer/1570-nz-linear-parcels), this layer provides the easiest way to create a relationship with associated tables such as [Parcel Title Association List](http://data.linz.govt.nz/table/1569-nz-title-parcel-association-list), [Parcel Statutory Actions List](http://data.linz.govt.nz/table/1565-nz-parcel-statutory-actions-list) and [Survey Affected Parcels List](http://data.linz.govt.nz/table/1568-nz-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](http://www.linz.govt.nz/survey-titles/landonline-data/landonline-bde/related-datasets/dcdb-datasets) 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](http://www.linz.govt.nz/about-linz/linz-data-service/dataset-information/cadastral-titles-data).

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 (http://www.linz.govt.nz/about-linz/news-publications-and-consultations/search-for-regulatory-documents/DocumentSummary.aspx?document=256). 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 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](http://data.linz.govt.nz/layer/772) and [non-primary](http://data.linz.govt.nz/layer/782) approved, current or historic linear parcels (see status flag descriptions for more information).

**This dataset has been replaced by the** [NZ Street Address](https://data.linz.govt.nz/layer/3353) **and will be deprecated on 31 May 2017**. It is currently being ported from the new database in an effort to minimise disruption for customers. See [Street Address Data Dictionary](https://data.linz.govt.nz/document/1627) for field mappings to the new dataset. This layer provides all allocated addresses as advised to LINZ by Territorial Authorities (TAs). Under the Local Government Act 1974 (section 319) it is the responsibility of the TAs to advise LINZ (the Surveyor General) of all allocated addresses in their district. ______________________ Local Government Act 1974 **319B Allocation of property numbers** (1) For electoral, postal, and other purposes the council may allocate a number to any area of land or building or part of a building within its district and may change the number allocated to any such area of land or building. (2) The council shall comply with any request from a Chief Surveyor to allocate a number to or change the number of any area of land or building or part of a building in its district. (3) The principal administrative officer shall advise the Chief Surveyor of the land district in which the land or building is situated of the numbers allocated under subsection (1) or subsection (2). ______________________ Generally allocated addresses will be represented by a single point. However there was an historical practice to represent only the principal address allocated by Territorial Authorities, and not include addresses assigned to individual flats. Similarly there was an historical practice to aggregate addresses into ranges, especially where there are many addresses for a single parcel. We are working (where possible) to resolve these historical anomalies and have each allocated address represented where possible. The datasets also includes addresses where the Surveyor General has requested (under the Local Government Act) that a TA allocated an address. The road name and locality fields attributed to an address are taken from the associated road attributes. These roads are stored as centrelines (see NZ Road Centre Line (Electoral)) and reflect the road names as assigned by the TA responsible. The locality name ensures that if duplicate road names exist in TA that the number/road combination can still be unique by using the locality field. Wherever address points have been provided in spatial data files by a TA, LINZ will import this data and use the exact location as defined by the TA. Where non spatial data is provided LINZ adds the location of an address point with the mandatory priority to locate that address point within the correct meshblock. The location of the front door of an elector's dwelling within the correct meshblock is a fundamental requirement of the electoral system (Section 72 Electoral Act 1993). Highly desirable priorities for the location of an address point are to have it in the same property and parcel as the dwelling and on the correct side of the physical and legal roads. It is also a desirable priority to have the address point in the same location as the dwelling and/or at the location of the property entrance.
