A layer file for the Auckland Council Unitary Plan Base Zone dataset. Download this file in conjunction with the Unitary Plan Base Zone.

Purpose:The coastal inundation hazard layers map describes the areas exposed to extreme water levels caused by storm tides, wave setup and sea-level rise under the following scenarios (where AEP is the Annual Exceedance Probability or the chance of occurring each year, ARI is the Average Recurrence Interval):20% AEP (5 year return)5% AEP (20 year return)2% AEP (50 year return)1% AEP (100 year return): to demonstrate present day risk in alignment with the Auckland Unitary Plan activity controls2% AEP (50 year return) + 1m sea level rise2% AEP (50 year return) + 2m sea level rise1% AEP (100 year return) + 1m sea level rise: in alignment with Auckland Unitary Plan activity controls1% AEP (100 year return) + 2m sea level rise: to demonstrate longer term risk with ongoing sea-level riseThis is a generalised version of the data. Download the original full dataset with layer files here:https://data-aucklandcouncil.opendata.arcgis.com/datasets/coastal-inundation-hazards-geodatabase/aboutThe layer takes into account extreme sea levels calculated between 2013 and 2019, as compiled in Carpenter, N., R Roberts and P Klinac (2020). Auckland’s exposure to coastal inundation by storm-tides and waves. Auckland Council technical report, TR2020/24. Auckland’s exposure to coastal inundation by storm-tides and waves (knowledgeauckland.org.nz)Sea-level rise values applied currently align with the projections by the Intergovernmental Panel on Climate Change sixth assessment report (2021), and the Ministry for the Environment (2022) Interim guidance on the use of new sea-level rise projections, which updates the Ministry for the Environment Coastal Hazards and Climate Change Guidance for Local Government (2017). In MfE’s (2022) Interim guidance, (excluding vertical land movement) one metre sea-level rise is projected to occur between 2095 - >2200, depending on the emission scenario used. Two metre sea-level rise is projected to occur in the longer term (beyond 2150). MfE’s (2022) Interim guidance recommends the inclusion of vertical land movement (VLM) in relative sea level rise considerations. These are not included in the above sea level rise predictions due to the high VLM variability across the region. Vertical land movement is generally predicted to increase the rates of relative sea level rise for the Auckland region so should also be incorporated in planning and design.Refer to Interim guidance on the use of new sea-level rise projections | Ministry for the Environment for more information on MfE’s interim guidance on sea level rise and vertical land movement.Lineage:3Extreme sea levels for the Auckland region were derived by NIWA in 2013 (Part 1 of Technical Report 2020/24). From 2016-2019, additional extreme sea level data was gathered for:The east coast estuaries (NIWA, 2016; Part 2 of Technical Report 2020/24)Parakai/Helensville Harbour (DHI, 2019; Part 3 of Technical Report 2020/24)Great Barrier Island (NIWA, 2019; Part 4 of Technical Report 2020/24)In 2020, these levels were projected onto the land topography (derived from the 2016-2018 LiDAR survey) by Stantec to establish the extent of coastal flooding.

This dataset is the definitive version of the annually released regional council boundaries for 2020 as defined by the regional councils and/or Local Government Commission, and maintained by Stats NZ (the custodian). This version contains 17 categories.

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.

Auckland Council unitary authority was formed in 2010, under the Local Government (Tamaki Makarau Reorganisation) Act 2009, replacing the Auckland Regional Council and seven territorial authorities.The seaward boundary of any coastal regional council is the twelve-mile New Zealand territorial limit. Regional councils are defined at meshblock and statistical area 2

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

This generalised version has been simplified for rapid drawing and is designed for thematic or web mapping purposes.

Digital boundary data became freely available on 1 July 2007.

Identifies the designations of requiring authorities as set out by s175(2) of the Resource Management Act 1991.

This dataset is classed as a 'draft' as further capture is being undertaken by the supplier to complete the project. A final, colour-balanced supply will be published once the project is fully captured.

Levels 21 - 23 (1:282 - 1:71)Aerial Imagery 24-25 Color Infrared covers aerial images for the Auckland Region in color infrared. Infrared aerial photography involves capturing images using infrared light, which is outside the visible spectrum. This type of photography is useful for a variety of applications, including environmental monitoring, agriculture, and land management. Infrared imagery can reveal details not visible to the naked eye, such as vegetation health, water stress, and temperature variations, making it valuable for assessing plant vitality, detecting heat sources, identifying areas of moisture, and infrastructure conditions, making it invaluable for environmental monitoring and urban planning.Data Acquisition:• Phase 1: Aerial photography was captured over the Auckland region and the Hunua Ranges covering approximately 2,051 km². The data was captured between September 2023 – April 2024.• Phase 2: Aerial photography was captured over the Auckland District, covering approximately 1,949 km². The data was captured between September 2023 – April 2024.• Phase 3: Aerial photography was captured for the Auckland District covering approximately 2,129 km². Data capture took place between March 2024 – April 2025.

Please contact us at gis@aklc.govt.nz to request the four-band imagery.The remaining areas that are not part of this product have been captured in 2025 and will be added to this service by end of 2025. Map Projection All spatial data for this project provided in terms of New Zealand Transverse Mercator 2000 map projection (NZTM2000). The ellipsoidal datum is New Zealand Geodetic Datum 2000 (NZGD2000). The airborne GPS and ground control GPS data was converted from ellipsoidal heights into orthometric heights using the LINZ NZGeoid16 separation model. For this project the orthometric vertical datum is New Zealand Vertical Datum 2016 (NZVD2016).EquipmentThe majority of the photography was captured using Vexcel's digital UltraCam Eagle Mark 3 (UCE-3) camera fitted with the 100 mm lens and flown at an altitude of approximately 4,732 ft (1,442 m) with the lowest ground GSD set at 0.075 m. This camera was fitted to a GSM 3000 gyro-stabilised mount and IGI AEROcontrol GNSS/IMU positioning system. Some portions were flown using Vexcel's digital UltraCam Lp (UCLp) camera fitted with the 70 mm lens and flown at an altitude of approximately 2,952 ft (900m).Sun Angle Imagery captured with a minimum sun angle of +40 degrees subject to a 5-degree tolerance when capture is in progress. It was agreed (February 2024) to lower the sun angle to +30 degrees over rural areas and +40 degrees over urban/city areas. The sun angle of the imagery used for the orthorectification ranged from 32 to 59 degrees.Urban Building Displacement Specification Urban 0.075 m GSD imagery using the UCE-3 camera and by flying with 60% forward overlap and with 35% sidelap (standard stereo coverage) will achieve <1 m building lean per 3 m height in the corners of the imagery used. Tall structures inwards of the corner of the frame will have less lean the closer to the nadir they are. <0.37 m building lean per 3 m of height in the corners of the imagery is using increased 80/80 overlap in the CBD area. Very tall buildings have been further straightened using manual techniques. To help reduce building lean in the CBD area additional processing has been applied to produce true orthos for building verticality. Ground Control A combination of existing control and LINZ benchmarks were observed for use with the aerial triangulation and bundle adjustment.DTM for Ortho Production The digital terrain model used for this project was derived from LiDAR DTM data flown in 2015. Outside the LiDAR DTM a new DTM was collected from the 0.075 m GSD stereo imagery using photogrammetric techniques, largely automated pixel matching and autocorrelation process. The DTM data was merged seamlessly and accuracy checked to meet the ortho imagery specification. The DTM was further processed and edited suitable for the ortho production.

This dataset is derived from the definitive versions of local boards for Auckland and territorial authorities for the rest of New Zealand, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ (the custodian), clipped to the coastline.

This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 21 local boards in the Auckland Council and 66 territorial authority boundaries for the rest New Zealand.

For statistical outputs that use territorial authorities to aggregate and report data Auckland Council is treated as a single geographic entity. This can hide meaningful patterns and trends for a significant portion of the population. A solution was to create a new classification of territorial authorities that includes the local boards for Auckland. The Auckland Council was established in 2010 under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Seven territorial authorities within the Auckland Region were abolished and replaced by the unitary authority Auckland Council. Local boards fall within the community board classification.

For CSV and Excel extracts, the Ecosystem Extent Domains document will assist in resolving domains. This layer has been created to assist the Council in identifying and managing threatened and at risk ecosystems in the Auckland region. The ecosystem classification system used in creating this layer was developed by the Department of Conservation (Singers & Rogers 2014) and refined by Nick Singers to match the specific nature of ecosystems found within the Auckland Region. For further information about the classification system, see Singers et al. (2015) Indigenous terrestrial and freshwater ecosystems of Auckland. The process of mapping the current extent of Auckland’s terrestrial and freshwater ecosystems has involved collating data and information from a variety of sources. For example, all terrestrial ecosystem data from past ecological surveys, held by legacy councils, was aggregated; numerous publications that documented the state of indigenous vegetation in Auckland were collated, including the Department of Conservation’s Protected Natural Area Programme survey reports and research papers for sites throughout the region. Ecological surveys carried out to potential SEAs assisted in filling knowledge gaps and to updating some of the existing data. The resulting data was used to inform the mapping of ecosystems. For further information on the ecosystems in the Auckland Region refer to:Singers, N.; Osborne, B.; Lovegrove, T.; Jamieson, A.; Boow, J.; Sawyer, J.; Hill, K.; Andrews, J.; Hill, S.; Webb, C. 2016.

For CSV and Excel extracts, the Ecosystem Extent Domains document will assist in resolving domains. The ecosystem classification used to map potential ecosystems of Auckland was developed by the Department of Conservation, as a tool for prioritizing ecosystem management (Singers & Rogers 2014). This classification is a synthesis that amalgamates previous classifications and ecological studies aligned to an abiotic framework. It describes a full range of ecosystem types at a variety of scales in an approximation of the natural or potential state as they would have been observed if people arrived today in New Zealand. For full details on the methodology used, see Singers (2014) A potential Ecosystem Map of Auckland.The Ecosystem Potential Extent layer was created by contractors Nick Singers and Colin Lawrence. The ecosystem classification system used in creating this layer was developed by the Department of Conservation (Singers & Rogers 2014) and refined by Nick Singers to match the specific nature of ecosystems found within the Auckland Region. The potential extent of Auckland’s original ecosystems has been modelled on historic vegetation spatial datasets (LENZ and NHF Pre-people) and categories were directly matched where possible. For ecosystem types where direct matching was not possible, climate, geography, geology and soil characteristics were used as determinants. For ecosystem types where environmental parameters are less specific, current-extent maps were used, and the associated geographical, geological and soil drivers for the sites mapped as a particular ecosystem type were used to extrapolate across the landscape. Historic mapping was cross-referenced with written accounts of original vegetation cover in the Department of Conservation’s Protected Natural Area Programme reports and other ecological district-wide survey reports. Historic mapping compiled for Awhitu and Manukau ecological districts by Landcare in 2000 was also used. For full details on the methodology used, see Singers (2014) A potential Ecosystem Map of Auckland. The layer was updated in July 2015 to reflect updated source information for MF25 on Little Barrier Island and MF24 in the Hunua Ranges.

This dataset is the definitive set of annually released community board boundaries for 2022 as defined by the territorial authorities and Local Government Commission but maintained by Stats NZ (the custodian), clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 187 categories.

Community boards are set up under the Local Government Act 2002 and Local Electoral Act 2001. Their purpose is to administer the affairs of communities with populations not less than 1,500 within rural, urban, or metropolitan districts of a territorial authority.

Local boards also fall within the community board classification. Local boards were introduced as part of the new local government arrangements for Auckland in 2010. Local boards share governance with a council’s governing body and each has complementary responsibilities, guaranteed by legislation. There are 21 local boards in the Auckland Council.

​

The regional council is the top tier of local government in New Zealand. Regional councils are defined under schedule 2, part 1 of the Local Government Act 2002. They were established in November 1989 after the abolition of the 22 local government regions. Regional council boundaries must coincide with meshblock boundaries under schedule 3, clause 17 of the Local Government Act 2002.

​

Regional council boundaries are based largely on water catchments, such as rivers, lakes, and harbours. The seaward boundary of the regions is the 12 mile (19.3km) New Zealand territorial limit. In determining regions, consideration was also given to regional communities of interest, natural resource management, land use planning, and environmental matters.

​

There are 16 regions which cover every territorial authority in New Zealand, with the exception of the Chatham Islands Territory (included in 99 Area Outside Region). Five regions are administered as unitary authorities, which function as both regional council and territorial authority. 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. Regional councils are responsible for administrating many environmental and transport matters, such as land transport planning and harbour navigation and safety.

​

Some regional council boundaries are coterminous with territorial authority boundaries, but there are several exceptions. An example is Taupo District, which is geographically split between four regions, although most of its area falls within the Waikato Region. Where territorial authorities straddle regional council boundaries, the affected area is statistically defined by complete regional councils. In general, however, regional councils contain complete territorial authorities.

​

Auckland Council unitary authority was formed in 2010, under the Local Government (Tamaki Makarau Reorganisation) Act 2009, replacing the Auckland Regional Council and seven territorial authorities.
