This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers:

• NZ Coastlines (Topo 1:50k)
• NZ Island Polygons (Topo 1:50k)
• NZ Auckland Is Island Polygons (Topo, 1:50k)
• NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)
• NZ Antipodes Is Island Polygons (Topo, 1:25k)
• NZ Kermadec Is Island Polygons (Topo, 1:25k)
• NZ Bounty Is Island Polygons (Topo, 1:25k)
• NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)
• NZ Chatham Is island polygons (Topo, 1:50k)

This topographic coastline is the line forming the boundary between the land and sea, defined by mean high water.

Islands from the NZ Island Polygons layer that lie within the NZ Coastline and Chatham Islands areas (i.e. islands in lakes, rivers and estuaries) have been removed.

The GIS workflow to create the layer is:

1. NZ Coastlines were converted from a polyline to a polygon using a polyline to polygon tool.
2. The resulting coastal polygon was then used as an input into an erase tool and run against the NZ Island Polygon layer to remove all islands lying within the NZ Mainland and Stewart Island.
3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k) that have had the islands within the main island polygon removed, NZ Auckland Is Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons (Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool.

The dataset represents the most current mapping of active faults for New Zealand in a single database, designed for portrayal at 1:250,000 scale. It is produced by GNS Science and derived from the QMAP Geological Map of New Zealand Project and the high-resolution New Zealand Active Faults Database (NZAFD-HighRes).

Active faults are defined as those that have ruptured and/or caused ground surface deformation during the last 125,000 years (except for in the Taupō Volcanic Zone / Taupō Rift, where the definition of activity is restricted to only include the last 25,000 years). This dataset includes only onshore active faults, with the exception of offshore faults that ruptured during the 2016 Kaikōura earthquake.

The 1:250,000 scale NZ Active Faults Database (NZAFD-AF250) is a feature class in vector format stored in a PostrgeSQL database. It comprises polylines, with each line representing the location of an active fault trace at or near the surface. Each fault trace has attributes that describe its name, orientation, displacement, sense of movement, time of last movement and other fault activity parameters.

The dataset is published to the GNS ArcGIS server as a web service layer which is intermittently updated with new information. The data can also be viewed through the NZAFD website and downloaded from there in shapefile, KML, JSON and text formats; however, these are not updated as frequently as the web service and are static copies of the database with the timestamp in the file name.

Statistical Area 2 2023 update

SA2 2023 is the first major update of the geography since it was first created in 2018. The update is to ensure SA2s are relevant and meet criteria before each five-yearly population and dwelling census. SA2 2023 contains 135 new SA2s. Updates were made to reflect real world change ofpopulation and dwelling growthmainly in urban areas, and to make some improvements to their delineation of communities of interest.

​

Description

This dataset is the definitive version of the annually released statistical area 2 (SA2) boundaries as at 1 January 2023 as defined by Stats NZ (the custodian), clipped to the coastline. This clipped version has been created for cartographic purposes and so does not fully represent the official full extent boundaries. This clipped version contains 2,311 SA2 areas.

SA2 is an output geography that provides higher aggregations of population data than can be provided at the statistical area 1 (SA1) level. The SA2 geography aims to reflect communities that interact together socially and economically. In populated areas, SA2s generally contain similar sized populations.

​

The SA2 should:

form a contiguous cluster of one or more SA1s,

excluding exceptions below, allow the release of multivariate statistics with minimal data suppression,

capture a similar type of area, such as a high-density urban area, farmland, wilderness area, and water area,

be socially homogeneous and capture a community of interest. It may have, for example:

· a shared road network,

· shared community facilities,

· shared historical or social links, or

· socio-economic similarity,

form a nested hierarchy with statistical output geographies and administrative boundaries. It must:

· be built from SA1s,

· either define or aggregate to define SA3s, urban areas, territorial authorities, and regional councils.

SA2s in city council areas generally have a population of 2,000–4,000 residents while SA2s in district council areas generally have a population of 1,000–3,000 residents.

In major urban areas, an SA2 or a group of SA2s often approximates a single suburb. In rural areas, rural settlements are included in their respective SA2 with the surrounding rural area.

SA2s in urban areas where there is significant business and industrial activity, for example ports, airports, industrial, commercial, and retail areas, often have fewer than 1,000 residents. These SA2s are useful for analysing business demographics, labour markets, and commuting patterns.

In rural areas, some SA2s have fewer than 1,000 residents because they are in conservation areas or contain sparse populations that cover a large area.

To minimise suppression of population data, small islands with zero or low populations close to the mainland, and marinas are generally included in their adjacent land-based SA2.

​

Zero or nominal population SA2s

To ensure that the SA2 geography covers all of New Zealand and aligns with New Zealand’s topography and local government boundaries, some SA2s have zero or nominal populations. These include:

· SA2s where territorial authority boundaries straddle regional council boundaries. These SA2s each have fewer than 200 residents and are: Arahiwi, Tiroa, Rangataiki, Kaimanawa, Taharua, Te More, Ngamatea, Whangamomona, and Mara.

· SA2s created for single islands or groups of islands that are some distance from the mainland or to separate large unpopulated islands from urban areas

· SA2s that represent inland water, inlets or oceanic areas including: inland lakes larger than 50 square kilometres, harbours larger than 40 square kilometres, major ports, other non-contiguous inlets and harbours defined by territorial authority, and contiguous oceanic areas defined by regional council.

· SA2s for non-digitised oceanic areas, offshore oil rigs, islands, and the Ross Dependency. Each SA2 is represented by a single meshblock. The following 16 SA2s are held in non-digitised form (SA2 code; SA2 name):

400001; New Zealand Economic Zone, 400002; Oceanic Kermadec Islands, 400003; Kermadec Islands, 400004; Oceanic Oil Rig Taranaki, 400005; Oceanic Campbell Island, 400006; Campbell Island, 400007; Oceanic Oil Rig Southland, 400008; Oceanic Auckland Islands, 400009; Auckland Islands, 400010 ; Oceanic Bounty Islands, 400011; Bounty Islands, 400012; Oceanic Snares Islands, 400013; Snares Islands, 400014; Oceanic Antipodes Islands, 400015; Antipodes Islands, 400016; Ross Dependency.

​

SA2 numbering and naming

Each SA2 is a single geographic entity with a name and a numeric code. The name refers to a geographic feature or a recognised place name or suburb. In some instances where place names are the same or very similar, the SA2s are differentiated by their territorial authority name, for example, Gladstone (Carterton District) and Gladstone (Invercargill City).

SA2 codes have six digits. North Island SA2 codes start with a 1 or 2, South Island SA2 codes start with a 3 and non-digitised SA2 codes start with a 4. They are numbered approximately north to south within their respective territorial authorities. To ensure the north–south code pattern is maintained, the SA2 codes were given 00 for the last two digits when the geography was created in 2018. When SA2 names or boundaries change only the last two digits of the code will change.

This dataset provides river name polygons for mainland New Zealand. It is part of a pilot to understand the benefit of combining river names and location, and making these openly available through the LINZ Data Service.

Unnamed rivers are also included in this dataset.

How this data can be used

Together with the NZ River Name Lines (Pilot) dataset, these are the first openly available datasets with NZ river names attributed to geometry features (lines and polygons). This data can be used for searching for a named river and zooming to its extents, extracting geometries of a named river, creating digital cartographic products displaying river names, and analysing other features against named rivers (e.g. identifying buildings or properties within a specified distance of a particular river).

Data vintage

The river names and extents in this dataset are based on the cartographic text shown on NZ Topo50 maps as of December 2018, and are an approximation and should not be taken as official. Further details are included in the 'Naming Extents Methodology' section in the 'Lineage' of this metadata. Please refer to the NZ River Name Lines and Polygons (Pilot) Data Dictionary for detailed metadata and information about this dataset.

Related data

NZ River Name Lines (Pilot) - contains smaller rivers captured as line features instead of polygons.

We recommend using the two river name datasets with the following NZ Topo50 layers for connectivity and visualisation of inland hydrographic features.

• NZ Coastlines (Topo, 1:50k)

• NZ Island Polygons (Topo, 1:50k)

• NZ Lagoon Polygons (Topo, 1:50k)

• NZ Lake Polygons (Topo, 1:50k)

• NZ Pond Polygons (Topo, 1:50k)

• NZ Swamp Polygons (Topo, 1:50k)

The NZ River Name Lines and Polygons (Pilot) Data Dictionary provides details on how to download the matching time period snapshots of this data.

Please note

• Official geographic names as listed in the New Zealand Gazetteer of place names must be used in all official documents as per the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

• This pilot dataset is unlikely to be updated, however feedback will be used for future enhancements to LINZ river datasets.

Mineral resource occurrence data covering the world, most thoroughly within the U.S. This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. While database records describe mineral resources worldwide, the compilation of information was intended to cover the United States completely, and its coverage of resources in other countries is incomplete. The content of MRDS records was drawn from reports previously published or made available to USGS researchers. Some of those original source materials are no longer available. The information contained in MRDS was intended to reflect the reports used as sources and is current only as of the date of those source reports. Consequently MRDS does not reflect up-to-date changes to the operating status of mines, ownership, land status, production figures and estimates of reserves and resources, or the nature, size, and extent of workings. Information on the geological characteristics of the mineral resource are likely to remain correct, but aspects involving human activity are likely to be out of date.

Coastal hydrosystems describe coastal features that span a gradient from near coast freshwater lakes/wetlands (lacustrine/palustrine environments) to marine. The term 'coastal hydrosystem' avoids the common error of referring to all such features as estuaries, mislabelling the numerous types that are non-estuarine and have different behavioural characteristics and management sensitivities from any truly estuarine environment. It also encompasses the coastal systems that do not represent end-of-river environments (e.g., some pocket beaches and embayments) or are so large and complex as to be fed by several freshwater drainage features (rivers, streams, wetlands) but which are dominated by none (e.g., some harbours, fjords, sounds and coastal-lacustrine systems). It also incorporates the multiple aspects of each system, including beaches, spits, barriers, river mouths, wetlands, saltmarshes and other geomorphic, ecological and hydrological features.

The New Zealand Coastal Hydrosystem classification (NZCH) is a classification of coastal hydrosystems within New Zealand including some offshore islands. The coastal hydrosystems classification is based on a hierarchical view of the abiotic components that comprise the environments of coastal hydrosystems. This classification presents detail at the geomorphic class level because this level is particularly important for coastal management and conservation needs at national and regional scales.

The primary GIS is the point layer. Supporting files (attached) include: a CSV database of environmental variables; GIS polygon layer; and Google Earth (.kmz) point and polygon exports.

The database, GIS and Google Earth files should be used in conjunction with the Classification of New Zealand's Coastal Hydrosystems report (Hume et al. 2016) (also attached) which documents a full description of the database, the calculation procedures and limitations to the variables.

The spreadsheet comprises a database of 500 New Zealand coastal hydrosystems and their associated environmental variables developed for the report.

The GIS point file comprises 500 New Zealand coastal hydrosystems and their associated environmental variables developed for the database. The environmental variables are mapped at 1:50,000 scale.

NOTE: Within the point attribute file -9999 represents the environmental variables with no data as shown in the spreadsheet as a blank cell. Make sure to exclude these values from analyses.

The polygon files comprise 420 New Zealand coastal hydrosystems depicting their general shape of the water body basin at high tide and upstream limit.

The .kmz files are derived from the NZCH GIS point and polygon layers for use with Google Earth.

The report provides a classification of coastal hydrosystems within New Zealand including some offshore islands. The coastal hydrosystems classification reconciles and clarifies coastal hydrosystem terminology and produces a hierarchy and classification of coastal wetland, riverine, estuarine and marine types. This report identifies and provides a list of environmental variables that describe the characteristics and properties of about 500 discrete coastal hydrosystems that can be used to provide national and regional statistics on coastal hydrosystems. An Identification Key is provided to guide the determination of the classes.

This web map can also be accessed via the LINZ Storymap about NZ Key Datasets for Resilience and Climate Change https://storymaps.arcgis.com/stories/b4dd46f15cea4234a098b4c8caae5b3d The River Environment Classification (REC) is a database of catchment spatial attributes, summarised for every segment in New Zealand's network of rivers. The attributes were compiled for the purposes of river classification, while the river network description has been used to underpin models. Typically, models (e.g. CLUES and TopNet) would use the dendritic (branched) linkages of REC river segments to perform their calculations. Since its release and use over the last decade, some errors in the location and connectivity of these linkages have been identified. The current revision corrects those errors, and updates a number of spatial attributes with the latest data. REC2 provides a recut framework of rivers for modelling and classification. It is built on a newer version of the 30m digital elevation model, in which the original 20m contours were supplemented with, for example, more spot elevation data and a better coastline contour. Boundary errors were minimized by processing contiguous areas (such as the whole of the North Island) together, which wasn't possible when the REC was first created. Major updates include the revision of catchment land use information, by overlaying with land cover database (LCDB3, current as at 2008), and the update of river and rainfall statistics with data from 1960-2006. The river network and associated attributes have been assembled within an ArcGIS geodatabase. Topological connectivity has been established to allow upstream and downstream tracing within the network. REC2 can be downloaded as a zip file and used directly in ArcMap. Alternatively, the layers can be extracted as shape files. The three REC2 based layers contained within this web map consist of the following (metadata is contained in the Layers section below).NZ Large Catchments, are basically the local watersheds of the REC2V5 dissolved into large sea draining catchments.River Environment Classification REC2 V5 (as National and local rivers) NZ Rivers and Names is a cut down version of the REC2V5 with river and waterway names added where available.

It is important to be clear about what ATES is applied to, because the scale at which it is applied could affect the category outcome. When an ATES assessment is done of a catchment or mountain range it is likely that the area has in it a mixture of simple, challenging and complex. The finer the scale used, the more definite things will be. When assessing a large area you should think about what sort of user goes there and the degree of use. If a lot of people use a specific place then this should be looked at separately. As an example a mountain range may generally be ‘challenging’ but contain areas of ‘complex’. It still meets the definition of ‘challenging’ because people have options for avoiding avalanche paths. If people are using a particular valley in the range where there is no option for avoiding avalanche terrain then that place is ‘complex’.ATES assessments of the New Zealand back country will occur over a period of time. The initial places done for visitor information should be popular DOC tracks in avalanche terrain and the more heavily used back country areas. Initially many of these assessments will be done as larger scale assessments of catchments and ranges in order to give visitors a general indication of the likely ATES class contained in that area. If other groups and organisations have a need for more detailed analysis to work out where they wish to operate, they will need to take these larger areas and split them into smaller blocks. This information can then be incorporated into information that DOC and the MSC supply to visitors. As guidebooks are written or revised it would be good if they could include the ATES classifications of the routes and trips in them. Assessing the terrain:ATES assessments should be done by a small group of people who are familiar with the terrain. At least one person in that group needs to have the stage 2 avalanche qualification. When the assessment is done an assesment form needs to be filled in for each area being assessed. Displaying the results:An ATES assessment can be displayed either through marking the classifications onto a map or by the use of a list. When putting ATES assessments onto maps this should be done in a GIS system with the simple terrain in green, challenging in blue and complex in black. Attributes for ATES shape files need to have name of the shape and Class in them. Class data needs to be 1 or 2 or 3.If the ATES assessment is being done as a text list then the colours should be used if possible either through the lists of each terrain class being in the appropriate colour or through the use of a coloured header bar.SimpleChallengingComplexAoraki Mount Cook VillageUpper Tasman GlacierGrand PlateauTasman Valley FloorMueller GlacierTrack to Mueller HutWhen preparing pamphlets the appropriate terrain class should be used in the text and reference made to the ATES system and where to get more information on it. The use of the terrain class on warning signs should also be encouraged.Public Information model:The following table is the public information model. This information will need to go into any web sites giving information on ATESand into ATES pamphlets and visitor centre information along with the accompanying advice on the amount of experience needed.DescriptionClassTerrain CriteriaSimple1Exposure to low angle or primarily forested terrain. Some forest openings may involve the run-out zones of infrequent avalanches. Many options to reduce or eliminate exposure. No glacier travel.Challenging2Exposure to well defined avalanche paths, starting zones or terrain traps; options exist to reduce or eliminate exposure with careful route-finding. Glacier travel is straightforward but crevasse hazards may exist.Complex3Exposure to multiple overlapping avalanche paths or large expanses of steep, open terrain; multiple avalanche starting zones and terrain traps below; minimal options to reduce exposure. Complicated glacier travel with extensive crevasse bands or icefalls.

This dataset is the definitive version of the annually released statistical area 3 boundaries as at 1 January 2023, defined by Stats NZ and concorded to higher geographies. This version contains 929 statistical 3 areas.

​

Statistical area 3 (SA3) is a new output geography, introduced in 2023, that allows aggregations of population data between the SA3geography and territorial authority geography.

​

This dataset is the definitive version of statistical area 3 (SA3) boundaries concorded to higher geographies for 2023 as defined by Stats NZ. This version contains 929 SA3s.

This statistical area 3 higher geographies file is a correspondence, or concordance, which relates SA3s to larger geographic areas or 'higher geographies'.

The higher geography contained in this concordance is: territorial authority (TA).

For more information please refer to the Statistical standard for geographic areas 2023.

This dataset is the definitive set of annually released regional council boundaries for 2022 as defined by the regional councils and/or Local Government Commission and maintained by Stats NZ (the custodian).

The regional council is the top tier of local government in New Zealand. There are 16 regional councils in New Zealand (defined by Part 1 of Schedule 2 of the Local Government Act 2002). Eleven are governed by an elected regional council, while five are governed by territorial authorities (the second tier of local government), who also perform the functions of a regional council and are known as unitary authorities.

These unitary authorities are Auckland Council, Nelson City Council, and Gisborne, Tasman, and Marlborough District Councils. The Chatham Islands Council also performs some of the functions of a regional council but is not strictly a unitary authority. Unitary authorities act as regional councils for legislative purposes.

The seaward boundary of any coastal regional council is the twelve-mile New Zealand territorial limit. Regional councils are defined at meshblock level. Statistical area 1 and statistical area 2 geographies nest within regional council boundaries.

Names are provided with and without tohutō/macrons. The name field without macrons is suffixed ‘ascii’.

NZ Suburbs and Localities describes the spatial extent and name of communities in urban areas (suburbs) and rural areas (localities) for navigation and location purposes.

The suburb and locality boundaries cover New Zealand including North Island, South Island, Stewart Island/Rakiura, Chatham Islands, and nearby offshore islands.

Each suburb and locality is assigned a name, major name, Territorial Authority and, if appropriate, additional in use names. A population estimate is provided for each suburb and locality by Stats NZ.

For more information please refer to the NZ Suburbs and Localities Data Dictionary and the LINZ Website

This 8m Digital Elevation Model (DEM) was originally created by Geographx (geographx.co.nz) and was primarily derived from January 2012 LINZ Topo50 20m contours (data.linz.govt.nz/layer/768).

Suitable for cartographic visualisation only. It was created by the interpolation of 20m contours with post-processing and filtering it is not suitable for terrain analysis.

Spatial accuracy is nominally the same as for the LINZ source data: 90% of well-defined points are within ±22 metres horizontally and within ±10 metres vertically.

For a full description of the how the DEM was generated refer to this layer’s metadata.
