NIWA has published a lake chart for every lake in New Zealand that can be surveyed, except for Lake Dunstan. The charts are of various scales that are determined to be the most appropriate for the size of the lake. The compilation of bathymetry from echo-sounding surveys with publication dates ranging from 1966 to 1989. This dataset also contains newly surveyed bathymetry using multibeam information. New data as and when available shall be added to this dataset. Some of the lakes may have more than one set of bathymetry files. The earlier one could be from the period 1966 to 1989 and the new information from recent surveys undertaken for comparison purposes.

The StockEx LSL 2021 proposed layer identifies proposed areas of "low slope land" where the Resource Management (Stock Exclusion) Regulations 2020 would apply if the low slope land map was updated as proposed in the "Stock exclusion regulations: Proposed changes to the low slope map" (MfE, 2021) discussion document. The layer shows the area of land defined as low slope land. These areas have a local mean slope is less than or equal to 5 degrees and are below 500m in altitude. Areas of lakes and ponds, estuarine open water, built-up areas, transport infrastructure, depleted grass, tall tussock grassland and urban parkland, as defined in Land Cover Database 5, are also excluded.

This provides a vector coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers: - [NZ Coastlines (Topo 1:50k)](http://data.linz.govt.nz/layer/258-nz-coastlines-topo-150k/) - [NZ Island Polygons (Topo 1:50k)](http://data.linz.govt.nz/layer/288-nz-island-polygons-topo-150k/) - [NZ Auckland Is Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/959-nz-auckland-is-island-polygons-topo-150k/) - [NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/932-nz-campbell-is-motu-ihupuku-island-polygons-topo-150k/)- [NZ Antipodes Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/978-nz-antipodes-is-island-polygons-topo-125k/) - [NZ Kermadec Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/908-nz-kermadec-is-island-polygons-topo-125k/)- [NZ Bounty Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/992-nz-bounty-is-island-polygons-topo-125k/) - [NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/893-nz-snares-is-tini-heke-island-polygons-topo-125k/) - [NZ Chatham Is island polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/86-nz-chatham-is-island-polygons-topo-150k/)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. 4. Lake Onoke from the NZ Lake Polygons (Topo 1:50k) layer and Te Whanga Lagoon from the NZ Chatham Is lagoon polygons (Topo, 1:50k) layer were then erased from the resultant polygon layer to include these two water bodies in the coastline definition. Coastline data from the Australian islands (Lord Howe, Norfolk, and Macquarie Is.) sourced from Geoscience Australia.

About the Postcode Network File:The Postcode Network File is the authoritative definition of the New Zealand Post Postcode Network. It includes approximately 1800 postcodes incorporating:• Urban delivery postcodes• PO Box and Private Bag postcodes• Rural Delivery (RD) postcodesThis is version V2021Q2V01Note: There are a number of additional locations used for counter delivery or Community Mail Box delivery that are not included in the Postcode Network File. This is because these locations are not official New Zealand Post Box Lobbies. A listing of these is available at www.nzpost.co.nz/postcodefinderThe primary purpose of postcodes is to assist in the efficient and accurate delivery of mail. Used in New Zealand since 1977, this major revision of postcodes is designed to provide a unique delivery address for all postal addresses on the New Zealand Post network. The postcode boundaries take into consideration New Zealand Post mail sorting requirements, the density of delivery addresses and the proximity of identical or similar street names. Please note that postcode boundaries do not necessarily reflect suburb boundaries. Urban and rural postal delivery postcodes are represented by a single-part or multi-part geographic area while postcodes associated with Box/Bag delivery are represented by a single point location (PO Box lobby). In rural areas the Rural delivery identifier (RD number) and New Zealand Post Mailtown is included and for Box/Bag lobbies the lobby name is listed.The Postcode Network File is designed to enable businesses and policy-makers to integrate postcodes within Geographic Information Systems (GIS) applications to assist in planning, modelling, business intelligence and decision making. The data can be represented in two dimensions (mapped) or modelledagainst other data such as physical addresses, city or town boundaries, census meshblocks and land valuation areas. Although the Postcode Network File includes full national coverage, it should be noted that not all physical addressescontained within a postcode boundary receive mail delivery from New Zealand Post. Note: The Postcode Network File is the intellectual property of New Zealand Post.

This dataset provides current outlines of buildings within mainland New Zealand captured from the latest aerial imagery. A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline. Building outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds. **Data vintage** This dataset shows the most recent set of building outlines extracted from the LINZ aerial imagery available on the LINZ Data Service. Current coverage includes nearly all regions of New Zealand, except parts of rural Auckland, remote parts of Bay of Plenty, Tasman and the Southern Alps, as well as Fiordland, Stewart Island and the Chatham Islands. This dataset will be updated and expanded as new aerial imagery becomes available. Since aerial imagery is flown only every few years in each region of the country, building outlines only reflect those buildings observed at the date of this aerial imagery capture, and may not reflect buildings constructed after this time period. Please refer to the [NZ Building Outlines Data Dictionary](https://nz-buildings.readthedocs.io/en/latest/introduction.html) for detailed metadata and information about this dataset. **Related building outlines data** [NZ Building Outlines (All Sources)](https://data.linz.govt.nz/layer/101292) - contains all combinations of building outlines from multiple years of imagery that have existed since the beginning of this dataset, and the dates when each building outline existed in the associated aerial imagery. [NZ Building Outlines Lifecycle](https://data.linz.govt.nz/table/101291) - is related to the dataset above and stores the relationship between building outlines when one building is split into two or more building outlines, or when multiple building outlines are merged into a single outline. --- **APIs and web services** This dataset is available via ArcGIS Online and ArcGIS REST services, as well as our standard APIs.
