This layer includes the current South Island pastoral leases as at the layer's latest revision date. It excludes pastoral leases that have completed Tenure Review, endowment land, special leases, pastoral occupation licences, pastoral vacant land and special leases. Lease boundaries have been derived from graphical cadastral line work held in LandOnline which in many cases was itself derived from the Lands and Survey Department's hard copy record sheets. The boundaries of many of these original Run Plans, on which these leases were based, were obtained from early Run Plans, circa 1860. As such please note that the boundaries are indicative only.

**Introduction** This dataset provides a 1 arc minute raster image of the free-air gravity anomalies, which have been downward continued to the ground surface (McCubbine et al, 2017). **Description** Gravity anomalies are differences between measured gravity (from the airborne gravity dataset) and an ellipsoidal model of the Earth’s gravity field (GRS80). Gravity anomalies correspond to un-modelled density variations within the Earth’s crust and upper mantle. They are used to investigate concealed geological structures and for quasigeoid modelling. These free-air anomalies show values which include gravitation impact of the topography. The national airborne gravity dataset is comprised of more than 50,000 linear km of flight observations, covering the three main islands of New Zealand and up to 10km offshore. As the airborne gravity dataset was measured at flight altitude, the observations have been reduced to the ground surface (a process known as downward continuation). The national airborne gravity dataset was collected as a joint project between Land Information New Zealand (LINZ), GNS Science (GNS) and Victoria University of Wellington (VUW). The airborne survey was completed in a total of eight months, over two campaigns: August – October 2013, and February – June 2014. **Users may also be interested other layers created for Bouguer anomalies at ground surface and the along track observations from the gravity flight lines at flight elevation** [NZ Airborne Gravity Bouguer Anomalies at Ground Surface (2013-2014)](https://data.linz.govt.nz/layer/3530) and [NZ Airborne Gravity Flight Lines at Elevation (2013-2014)](https://data.linz.govt.nz/layer/3531).

This table records which current primary parcels are contained with DOC Administered Protected Areas. Most Protected Areas will be made up of more than one primary parcels. This table can be used to link the [DOC Administered Protected Areas](https://data.linz.govt.nz/layer/3564-protected-areas/) dataset to parcel layers such as [NZ Parcels](https://data.linz.govt.nz/layer/1571-nz-parcels/), [NZ Linear Parcels](https://data.linz.govt.nz/layer/1570-nz-linear-parcels/) or [NZ Primary Parcels](https://data.linz.govt.nz/layer/772-nz-primary-parcels/) DOC cannot guarantee the accuracy of the information contained in this table, but rather it represents best endeavours to maintain an accurate record of conservation land.

This table is used to associate LINZ Managed Crown Properties to current primary spatial parcels. For some records, there is a one to many relationship between properties and parcels. This table can be used to link the [LINZ Managed Crown Property](https://data.linz.govt.nz/layer/3358-linz-managed-crown-property/) dataset to parcel layers such as [NZ Parcels](https://data.linz.govt.nz/layer/1571-nz-parcels/), [NZ Linear Parcels](https://data.linz.govt.nz/layer/1570-nz-linear-parcels/) or [NZ Primary Parcels](https://data.linz.govt.nz/layer/772-nz-primary-parcels/) More information on Crown Property can be found under the [Crown Property section](http://www.linz.govt.nz/crown-property) on the LINZ Website.

This layer includes all Crown Land and Properties managed by LINZ which have been identified spatially and can include properties managed by LINZ on behalf of other agencies. The attributes in this dataset are derived from the National Property and Land Information System (NaPALIS), which is a centralised database for all Land Information New Zealand (LINZ) and Department of Conservation (DOC) administered land. The boundaries of many properties are linked to the applicable Landonline Primary Parcel(s), but in some cases the boundaries may have been drawn in as unsurveyed parcels to varying degrees of accuracy. As such please note that the boundaries are indicative only. The layer excludes any LINZ managed properties which do not have an identified location or extent. More information on Crown Property can be found under the [Crown Property section](http://www.linz.govt.nz/crown-property) on the LINZ Website. A subset of Crown Property can be found in the [South Island Pastoral Leases layer](https://data.linz.govt.nz/layer/1572-south-island-pastoral-leases/). A table of Property associations to Primary Parcels is published in the [LDS here](https://data.linz.govt.nz/table/3450-property-parcel-association/).

This Protected Area Layer contains land and marine areas, most of which are administered by the Department of Conservation Te Papa Atawhai (DOC) and are protected by the Conservation, Reserves, National Parks, Marine Mammal and Marine Reserves Acts. All of the areas have been identified spatially. The attributes in this dataset are derived from the National Property and Land Information System (NaPALIS), which is a centralised database for all DOC and LINZ administered land. The boundaries for most protected areas are derived from the Landonline Primary Parcel(s). In some cases, the boundaries may have been based on unsurveyed parcels defined to varying degrees of accuracy. As such please note that the boundaries are indicative only. The dataset includes reserves but it is not a complete set. Privately owned reserves are excluded from the dataset as they are not crown land. Also, the dataset does not contain a complete list of reserves “vested” in Local Authorities or “controlled and managed” by other organisations. The dataset is continually being updated however as errors or omissions are discovered and new land transactions are completed. The Department cannot guarantee the accuracy of the infromation but rather it represents best endeavours to maintain an accurate record of conservation land. A table of Protected Area associations to Primary Parcels is published in the [LDS here](https://data.linz.govt.nz/table/3561-protected-area-parcel-association/).

This data collection contains observations from moored instruments primarily from New Zealand and Antarctic waters deployed by the National Institute of Water and Atmospheric Research (NIWA) and its predecessor the DSIR. Data was sourced from a range of instrumentation over many decades, with primary measured variables including temperature, pressure, salinity, and current speed/direction. More recently, other chemical and biological variables may be found within data records. Data quality checking is variable but mostly quality controlled to remove bad data using visual checks on records – see individual un-subsetted files for specific information relating to contained data.
