Detailed information about foundation requirements is available on the Ministry of Business, Innovation and Employment (MBIE)website.Technical category information is provided on behalf of the Ministry for Business, Innovation and Employment (MBIE) and was the best information available at the time of publication on Canterbury Maps in 2017. A technical category (1, 2 or 3) was assigned to residential properties on flat land in parts of Christchurch City, and Selwyn and Waimakariri districts by MBIE following the 2010/11 earthquakes. The technical categories were established to provide guidance on appropriate geotechnical assessments and foundation solutions for house repairs and reconstruction during the earthquake recovery. The technical categories were intended to have a limited life and were not intended to be updated over time. Details of any work done on an individual property since 2010 to reduce the liquefaction susceptibility of the land, or investigations that show the land meets the definition of another technical category, should be provided to prospective buyers, insurance companies or Christchurch City Council, Waimakariri District Council or Selwyn District Council.Published in the gazetted Land Use Recovery Plan 6/12/2013 https://cera.govt.nz/recovery-strategy/built-environment/land-use-recovery-planTechnical Category 1 (TC 1)Land that was classified Technical Category 1 (TC1) was suitable for homes to be repaired or rebuilt after the 2010/11 Canterbury earthquakes.TC1 land generally did not experience liquefaction-related land damage or settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is unlikely on TC1 land during significant future earthquakes. Standard foundations for concrete slabs or timber floors are considered adequate to address liquefaction hazard for house repairs and rebuilds on TC1 land, but normal consenting requirements still apply (e.g. to confirm suitable ground bearing strength and assess all other hazards).Technical Category 2 (TC 2)Land that was classified Technical Category 2 (TC2) was suitable for homes to be repaired or rebuilt after the 2010/11 Canterbury earthquakes. TC2 land may have experienced liquefaction-related land damage and settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is possible on TC2 land in future significant earthquakes. While TC2 land is considered suitable for residential construction, stronger foundations are required for house repairs and rebuilds. This may include standard timber piled foundations for houses with lightweight cladding and roofing and suspended timber floors or enhanced concrete foundations.Technical Category 3 (TC 3)TC3 land experienced liquefaction-related land damage and settlement during the 2010/11 Canterbury earthquakes. Land damage from liquefaction is possible on TC3 land in future significant earthquakes. While TC3 land is considered suitable for residential construction, site-specific geotechnical investigation and specific engineering foundation design are required for house repairs and rebuilds.There are no one-size-fits-all foundation solution for repairs or rebuilds on TC3 land. Site-specific geotechnical investigations will identify the best foundation for the repair or rebuild to reduce the risk of property damage or injury in future earthquakes. This may include deep foundation piles or ground improvement work.N/A - Port Hills & Banks PeninsulaProperties in parts of the Port Hills and Banks Peninsula have not been given a Technical Category. This is because properties in the hill areas have always required a site-specific foundation design and are not generally subject to liquefaction or lateral spread.Normal consenting procedures will apply in these areas.N/A - Rural & UnmappedProperties in rural areas or beyond the extent of land damage mapping, and properties in parts of the Port Hills and Banks Peninsula have not been given a Technical Category.Normal consenting procedures will apply in these areas.N/A - Urban NonresidentialTechnical Category not applicable means that non-residential properties in urban areas, properties in rural areas or beyond the extent of land damage mapping, and properties in the Port Hills and Banks Peninsula have not been given a Technical Category.Normal consenting procedures will apply in these areas.Red Zone (Port Hills)Red Zone (Port Hills) are areas where the threat to life from cliff collapse or rocks rolling downhill was considered unacceptable following the 2010/11 Canterbury earthquakes. The areas were defined by the Canterbury Earthquake Recovery Authority (CERA). The Crown offered to purchase properties in these areas from the owners, and the properties that were sold to the Crown are now administered by Land Information New Zealand (LINZ) and/or Christchurch City Council. You can find more information on the LINZ website LINZ website. Some properties were not sold to the Crown and in some cases the owners have subsequently installed mitigation works to reduce the cliff collapse or rockfall risk to an acceptable level. Details of any work done to reduce the cliff collapse or rockfall risk to individual properties should be provided to prospective buyers and insurers.Red Zone (Port Hills) areas within Christchurch City are now part of Christchurch City Council’s slope instability hazard management areas. You can find more information on these management areas in Chapter 5 of the Christchurch District Plan, and find more information on Port Hills slope stability on the Christchurch City Council website.Red Zone Christchurch & WaimakariThe Red Zone (Flat Land) areas are where the Crown offered to purchase properties from the owners after 2010/11 Canterbury earthquakes. The Government considered that making the land suitable to build on again and repairing roads and underground services in these areas would be very expensive and take a very long time. It gave property owners in these areas the option to sell their properties to the Crown so that they could resettle more quickly. The areas were defined by the Canterbury Earthquake Recovery Authority (CERA) and the properties that were sold to the Crown are now administered by Land Information New Zealand (LINZ). You can find more information on the LINZ website. Red zone flat land areas within Christchurch City are now part of Christchurch City Council’s Specific Purpose (Flat Land) Recovery Zone. You can find more information on this zone on the Christchurch District Plan.CCC Liquefaction & CERA InformationIn 2019 Christchurch City Council completed a liquefaction hazard study , encompassing the Christchurch urban area, which uses the extensive information about ground conditions gathered since the 2010/11 Canterbury earthquakes and follows the most recent national liquefaction guidance. This includes an updated liquefaction vulnerability map, and an online tool which helps to visualise an area’s vulnerability to liquefaction under different conditions. For details visit the CCC liquefaction information website. You can find out more information about the inherited responsibilities of the Canterbury Earthquake Recovery Authority (CERA) on the Department of the Prime Minister and Cabinet website.

This entity describes Canterbury Earthquake Recovery Authoritys (CERA) broad classification (eg, Red Zone, Orange Zone, etc) of earthquake land damage within Christchurch, indicating what stage the land assessment process is at and if concluded, whether or not it will be possible to rebuild on the land. Areas currently zoned Orange will progressively be reclassified as either Red or Green. Areas zoned Green are further classified into technical categories - refer QuakeFoundationDesign entity.Data Source is Tonkin & Taylor who supply updates as a WFS feed on behalf of CERA. The data is 'maintained' inhouse via a bulk archive of existing records from QuakeLandZone then running of an app to repopulate with the latest CERA update. This feature will be intersected with stRatingUnitCentroid for the purposes of Spatial Significance Comment generation and QuakeLandZone records MUST therefore be disassociated BEFORE being archived.It is spatially abstracted to an area.Entity type Concept.

This soil map for Christchurch City was compiled at 1:25,000 scale from several published and unpublished soil maps held by Landcare Research including:

Christchurch Region NZ Soil Survey Report 16 1:63 360 Part Paparua County NZ Soil Bureau Bulletin 34 1:31 860 Part Port Hills NZ Soil Bureau Bulletin 35 1:31 860 Heathcote County NZ Soil Bureau Report 1 1:31 860 Part Port Hills unpublished map 1:10 000 Sumner region NZ Soil Survey Report 70 1: 8 000

The database was constructed containing attributes relating to land use for each map unit and three land use interpretations generated: horticultural versatility, land use capability and urban suitability.

Footnotes

Geographical boundaries

Statistical standard for geographic areas 2023 (updated December 2023) has information about geographic boundaries as of 1 January 2023. Address data from 2013 and 2018 Censuses was updated to be consistent with the 2023 areas. Due to the changes in area boundaries and coding methodologies, 2013 and 2018 counts published in 2023 may be slightly different to those published in 2013 or 2018.

​

Subnational census usually resident population

The census usually resident population count of an area (subnational count) is a count of all people who usually live in that area and were present in New Zealand on census night. It excludes visitors from overseas, visitors from elsewhere in New Zealand, and residents temporarily overseas on census night. For example, a person who usually lives in Christchurch city and is visiting Wellington city on census night will be included in the census usually resident population count of Christchurch city.

​

Caution using time series

Time series data should be interpreted with care due to changes in census methodology and differences in response rates between censuses. The 2023 and 2018 Censuses used a combined census methodology (using census responses and administrative data), while the 2013 Census used a full-field enumeration methodology (with no use of administrative data).

​

About the 2023 Census dataset

For information on the 2023 dataset see Using a combined census model for the 2023 Census. We combined data from the census forms with administrative data to create the 2023 Census dataset, which meets Stats NZ's quality criteria for population structure information. We added real data about real people to the dataset where we were confident the people who hadn’t completed a census form (which is known as admin enumeration) will be counted. We also used data from the 2018 and 2013 Censuses, administrative data sources, and statistical imputation methods to fill in some missing characteristics of people and dwellings.

​

Data quality

The quality of data in the 2023 Census is assessed using the quality rating scale and the quality assurance framework to determine whether data is fit for purpose and suitable for release. Data quality assurance in the 2023 Census has more information.

​

Quality rating of a variable

The quality rating of a variable provides an overall evaluation of data quality for that variable, usually at the highest levels of classification. The quality ratings shown are for the 2023 Census unless stated. There is variability in the quality of data at smaller geographies. Data quality may also vary between censuses, for subpopulations, or when cross tabulated with other variables or at lower levels of the classification. Data quality ratings for 2023 Census variables has more information on quality ratings by variable.

​

Census usually resident population count concept quality rating

The census usually resident population count is rated as very high quality.

Census usually resident population count – 2023 Census: Information by concept has more information, for example, definitions and data quality.

​

Using data for good

Stats NZ expects that, when working with census data, it is done so with a positive purpose, as outlined in the Māori Data Governance Model (Data Iwi Leaders Group, 2023). This model states that "data should support transformative outcomes and should uplift and strengthen our relationships with each other and with our environments. The avoidance of harm is the minimum expectation for data use. Māori data should also contribute to iwi and hapū tino rangatiratanga”.

​

Confidentiality

The 2023 Census confidentiality rules have been applied to 2013, 2018, and 2023 data. These rules protect the confidentiality of individuals, families, households, dwellings, and undertakings in 2023 Census data. Counts are calculated using fixed random rounding to base 3 (FRR3) and suppression of ‘sensitive’ counts less than six, where tables report multiple geographic variables and/or small populations. Individual figures may not always sum to stated totals. Applying confidentiality rules to 2023 Census data and summary of changes since 2018 and 2013 Censuses has more information about 2023 Census confidentiality rules.

The dataset shows zones of different liquefaction susceptibility within Hurunui district.The dataset is based on the 1:250,000 liquefaction potential maps (Figures 2 and 3) in McCahon (2011) Liquefaction hazard in Hurunui District. Environment Canterbury report number R11/61, but uses the more accurate boundaries of geological units directly from the GNS Science QMAP (1:250,000) geological map series (Greymouth, Kaikoura and Christchurch map sheets) as the zone boundaries. The McCahon (2011)report also used the surface geology from the GNS Science QMAP series, with limited borehole information, to delineate areas of liquefaction potential, but the maps in the report were not developed in GIS and are not adequately georeferenced. NOTE: The southeastern part of this dataset (around Leithfield, Leithfield Beach and Amberley Beach) has been superseded by Brackley (comp), 2012, Review of liquefaction hazard information in eastern Canterbury, including Christchurch City and parts of Selwyn, Waimakariri and Hurunui Districts. Environment Canterbury report R12/83.

The dataset shows zones of different liquefaction susceptibility within Waimakariri district.The dataset is based on the 1:250,000 liquefaction potential maps (Figure7.1) in Yetton & McCahon (2009) Earthquake Hazard Assessment for Waimakariri District. Environment Canterbury report number R09/32, but uses the more accurate boundaries of geological units directly from the GNS Science QMAP (1:250,000) geological map series as the zone boundaries. The Yetton & McCahon (2009) report also used the surface geology from the GNS Science QMAP series, with limited borehole information, to delineate areas of liquefaction potential, but the maps in the report were not developed in GIS and are not adequately georeferenced. NOTE: The eastern part of this dataset has been superseded by Brackley, H. (comp), 2012, Review of liquefaction hazard information in Eastern Canterbury, including Christchurch City and parts of Selwyn, Waimakariri and Hurunui Districts. Environment Canterbury report number R12/83.

This dataset is the definitive version of the annually released territorial authority boundaries as at 1 January 2023 as defined by territorial authorities and/or Local Government Commission, and maintained by Stats NZ (the custodian). This version contains 67 territorial authorities, excluding ‘area outside territorial authority’.

​

Territorial authorities are the second tier of local government in New Zealand, below regional councils. They are defined under schedule 2, part 1 of the Local Government Act 2002 as city councils or district councils. Territorial authorities were established in 1989 when 205 territorial local authorities were replaced by 75 territorial authorities. Territorial boundaries must coincide with meshblock boundaries under schedule 3, clause 17 of the Local Government Act 2002.

​

There are 67 territorial authorities: 12 city councils, 53 district councils, Auckland Council, and Chatham Islands Council. Five territorial authorities (Auckland Council, Nelson City Council, and the Gisborne, Tasman, and Marlborough district councils) also perform the functions of a regional council and are therefore unitary authorities. The Chatham Islands Council performs some regional council functions.

​

Some territorial authority boundaries are coterminous with regional council boundaries but there are several exceptions. An example is Taupo District, which is split between four regions, although most of its area falls within the Waikato Region. When defining the boundaries of territorial authorities, the Local Government Commission bases considerable weight on the ‘community of interest’.

​

Territorial authorities are defined at meshblock level. Statistical area 1, statistical area 2 and statistical area 3 geographies nest within territorial authority boundaries.

​

Maintenance

Local government boundaries may be changed through the Local Government Act 2002, an Act of Parliament, or a natural process such as the middle line of a river changing its natural course.

​

The Territorial Authority classification is released annually on 1 January to coincide with the update of meshblocks, but there are not always changes from the previous classification.

​

1989:

New Zealand’s local government structural arrangements were significantly reformed by the Local Government Commission in 1989. Prior to reformation there were 205 territorial local authorities: 28 cities, 78 boroughs, 67 counties, 31 districts, and 1 town district, as well as a multitude of ad-hoc authorities such as pest control boards, drainage boards, catchment boards, and domain and reserve boards.

​

These were replaced by 74 territorial local authorities, 15 of which were cities and 58 districts. The exception was Chatham Islands County which retained its county status.

​

1990:

Invercargill was proclaimed a city.

​

1992:

Nelson-Marlborough Regional Council was abolished by a Local Government Amendment Act. Kaikoura District was transferred to the Canterbury Region. Nelson City, and Tasman and Marlborough districts became unitary authorities.

​

1995:

The Chatham Islands County was dissolved and reconstituted by a specific Act of Parliament as the "Chatham Islands Territory", with powers similar to those of territorial authorities and some functions similar to those of a regional council. This included the addition of territorial sea, a coastal buffer extending to twelve nautical miles from the coastline.

​

1995:

Tasman District boundary extended to align with the Tasman Region boundary at the 12-mile limit.

​

1998:

Not Applicable category changed to Area Outside Territorial Authority

​

2004:

Tauranga District changed to Tauranga City.2006:Banks Peninsula District merged into Christchurch City as a result of a Local Government Commission decision following a 2005 referendum.

​

2010:

Auckland Council established under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Rodney District, North Shore City, Waitakere City, Auckland City, Manukau City, Papakura District, and Franklin District territorial councils, and the Auckland Regional Council, were abolished to become a unitary authority known as the Auckland Council. The area now consists of one city council (with statutory provision for three Māori councillors), 13 wards, and 21 local boards.

​

2015:

Wanganui District Council name changed to Whanganui District Council effective 1 December 2015.

​

2020:

Otorohanga District Council name amended to Ōtorohanga District Council.

​

Opotiki District Council name amended to Ōpōtiki District Council.

​

Both changes were under schedule 2 of the Local Government Act 2002 and effective 17 January 2020.

​

2021:

A local government reorganisation transferred land between two territorial authorities, Western Bay of Plenty District and Tauranga City. The changes took effect on 19 February 2021 under schedule 3 of the Local Government Act 2002. Refer to the New Zealand Gazette notice for further details.

​

Numbering

The territorial authority classification is a flat classification. Territorial authorities are given a unique three-digit code. The classification contains 68 categories (including ‘999 – Area Outside Territorial Authority’).

OverviewThe fault awareness areas and fault avoidance zone show areas where there may be a surface fault rupture hazard. Surface fault rupture is the permanent breaking, ripping, buckling or warping of the ground on or near the line where a fault meets the ground surface, as a result of an earthquakeon the fault. It is different from earthquake shaking.The fault awareness areas are derived from faults mapped at a broad scale of 1:250,000 for Environment Canterbury by GNS Science between 2009 and 2019: Kaikoura (2015, updated 2019), Hurunui (2012), Waimakariri (2013, updated 2019), Selwyn (2013), Ashburton (2009), Timaru (2017), Mackenzie (2010), Waimate (2017) and Waitaki (2017). There is no dataset for Christchurch City as there are no known earthquake faults at the ground surface in the Christchurch City or Banks Peninsula area.This dataset has been created as recommended in Barrell, et al, 2015, Guidelines for using regional-scale earthquake fault information in Canterbury. GNS Science Consultancy Report 2014/211. A 125m or 250m buffer was placed around the mapped fault traces to create this polygon dataset, depending on how certain the fault is, and how well expressed it is at the ground surface. Definite (well expressed and moderately expressed) fault and monocline records and likely (well expressed and moderately expressed) fault and monocline records have a 125m buffer, recognising that the mapped location of the fault is fairly well constrained and is reasonably close the actual location. All other faults and monocline records have a 250m buffer, recognising the the mapped location is not as well constrained. See Barrell, et al, 2015 for a full description of the method used to create this polygon dataset, and recommended actions for each type of area.The fault avoidance zones are derived from more detailed fault mapping (generally 1:10,000 or better, using LiDAR) undertaken between 2004 and 2024 for faults closer to populated areas where more detailed mapping is needed for land use planning. These include: several faults in Kaikoua, the Hanmer Fault (Hurunui District), Ashley Fault (Waimakariri District), Greendale Fault (Selwyn District) and the Ostler Fault (Mackenzie District). Descriptions of the attribute fields:Name: Fault name, generally taken from the district fault name field (e.g. KDC_name) in the district fault datasets or the fault name in the fault avoidance zone datasets. Some of these have been changed or updated from the original district fault names to make them consistent with fault names in neighbouring districts.Zone:Fault zone that the fault is within, if any.Certainty:The level of confidence that the mapped feature is in fact an active earthquake fault - definite, likely or possible. See Barrell, et al, 2015 for full descriptions.Surface form:How clearly the mapped feature can be seen at the ground surface - well expressed, moderately expressed, not expressed or unknown. See Barrell, et al, 2015 for full descriptions.Min RI:Minimum fault recurrence interval, taken from the summary table of each district fault report, or updated with more recent information.Max RI:Maximum fault recurrence interval, taken from the summary table of each district fault report, or updated with more recent information.Min RI Class:Minimum fault recurrence interval class (as defined in Kerr, et al, 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report, or updated with more recent information. Some values have been changed to better match the minimum fault recurrence interval.Max RI Class:Maximum fault recurrence interval class (as defined in Kerr, et al 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report, or updated with more recent information. Dom sense:Dominant sense of movement on fault - dextral (strike-slip), sinistral (strike-slip), reverse, thrust or normal. Kept from the 1:250,000 GNS Science QMAP series fault attributes, where given.Sub sense:Secondary sense of movement on fault - dextral (strike-slip), sinistral (strike-slip), reverse, thrust or normal. Kept from the 1:250,000 GNS Science QMAP series fault attributes, where given.Down quad:Which side of the fault has gone down relative to the other side. Kept from the 1:250,000 GNS Science QMAP series fault attributes, where given.District:District that fault is within.Buffer: Whether a 125m or 250m buffer has been applied to the fault to create the fault awareness area as per Barrell, et al, 2015. Or the buffer distance used for fault avoidance zonation.Poly_type: Whether the polygon is a fault awareness area or a fault avoidance zone, as described above.Date: Year the information was created.Report: Report that accompanies the information.Author: The organisation that created the information.Complexity: The complexity of fault deformation within a fault avoidance zone (for fault avoidance zones only).Base_data: The original dataset that the fault awareness area or fault avoidance zone is based on.Base_scale: The scale at which the fault mapping was originally undertaken.Rept_link: Hyperlink to accompanying report.
