Seven legacy systems were migrated to Auckland Council’s GIS environment where the creation of new assets and maintenance of existing assets are now being undertaken. Using asbuilts sent to the stormwater team from development engineers and/or internal projects, the geometry and attributes of stormwater assets are captured using standard ArcGIS editing functionality. Whilst due care has been taken to capture the assets as accurately as possible, the data is indicative and cannot be considered to align to any particular boundaries or features including cadastral.

The Auckland Urban Stream Survey – conducted by the Waterways Centre between April 8 and 9, 2024 – delivered high-resolution, high-fidelity terrain models to support Auckland Council’s Making Space for Water initiative. Waterways Centre used a bidirectional gridded acquisition flight plan using the VUX-240 sensor to capture LiDAR data of the Pakuranga Creek and Cockle Bay catchments as well as the eastern portion of the Whau catchment (Blockhouse Bay). A dense colourised 3D point cloud data was generated along with a push-button orthophotography at 0.1 m resolution.

"River flow refers to the quantity of water passing a point in the river over a certain amount of time. Different rivers have different flow patterns, such as sharp peak flows following rain with low flows in between, or high spring flows from snow melt. These flow characteristics affect how much water is available for irrigation, drinking water, hydro–electric power generation, and recreational activities such as fishing and boating. River flows are also very important for maintaining the health and form of a waterway.

This dataset relates to the "Geographic pattern of natural river flows" measure on the Environmental Indicators, Te taiao Aotearoa website. "

REC2 (River Environment Classification, v2.5) - June 2019 [Hosted Feature Layer]This service depicts rivers as lines and catchments as polygons 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 re-cut 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 minimised by processing contiguous areas (such as the whole of the North Island) together, which wasn't possible when it was originally created.Major updates include the revision of catchment land use information, by overlaying with the 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 or streamed and used directly in ArcMap. (A file geodatabase version for ArcGIS of REC2 can be downloaded as a zip file and used directly for analyses in ArcMap from here)This layer is using Esri's ArcGIS Online Optimizations for fast rendering.This is REC2 (Version 5) , June 2019 - a publicly available dataset from NIWA Taihoro Nukurangi.NIWA acknowledges funding from the MBIE SSIF towards the preparation of REC v2.5Coordinate Reference System: NZTM (New Zealand Transverse Mercator, EPSG: 2193)Geometric Representation of Rivers: LinesExtent (Bounding Box):

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.

Data has been created from hosted feature service (https://mapping.gw.govt.nz/arcgis/rest/services/GW/NRPMap_P_operative/MapServer). It has been shared to the Open Data Portal. Schedule M1: Surface water community drinking water supply abstraction points This feature class identifies the community drinking supply catchments to which policies and rules in the Plan apply in order to give effect to the The National Environmental Standard (NES) for Sources of Human Drinking Water (2007). The NESfor Sources of Human Drinking Water (2007) directs regional councils to consider the potential impacts of land use activities on community drinking water supplies. This map defines the ‘source protection zones’ for all relevant community drinking water supply points. The zones describe the area within which an activity might reasonably be expected to impact upon the quality of water at the abstraction point.The extent of the source protection area was defined by the ‘run time’ it would take water entering the stream to reach the abstraction point. Different catchments have different run times based on catchment characteristics. The catchment drinking water supply protection zone is a 200 m wide buffer overlaid on this defined river-run extent. More information can be found in the report:Thompson, M. (2015), Delineation of drinking water supply catchment protection zones (surface water): Method to support the Proposed Natural Resources Plan.

The Auckland Urban Stream Survey – conducted by the Waterways Centre between April 8 and 9, 2024 – delivered high-resolution, high-fidelity terrain models to support Auckland Council’s Making Space for Water initiative. Waterways Centre used a bidirectional gridded acquisition flight plan using the VUX-240 sensor to capture LiDAR data of the Pakuranga Creek and Cockle Bay catchments as well as the eastern portion of the Whau catchment (Blockhouse Bay). A dense colourised 3D point cloud data was generated along with a push-button orthophotography at 0.1 m resolution.
