This layer provides the **current** strata parcel polygons and their associated descriptive data as a single layer to facilitate their use independently of other primary parcels or non primary parcels.
Strata parcels are portions of land where the vertical extent is limited.
The combination of this layer with the primary parcels layer provides all current parcels for New Zealand (i.e. excludes Historic and Pending parcels)
If you require approved or historic parcels see the [All Parcels Layer](http://data.linz.govt.nz/layer/1571-nz-all-parcels)
This layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the [Survey Boundary Marks](http://data.linz.govt.nz/layer/774-nz-survey-boundary-marks) layer which contains accuracies for each parcel node.
The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. For more information [see](http://www.linz.govt.nz/about-linz/linz-data-service/dataset-information/cadastral-titles-data)
LINZ and its predecessors have been responsible for cadastral data in New Zealand for more than a hundred years.
Prior to LINZ, strata parcels were not generally mapped i.e. drawn on the various cadastral record sheets undertaken as part of the maintenance and indexing roles of the department, but some were captured for the subsequent Digital Cadastral Database (DCDB).
The DCDB provided the graphical index to survey records throughout New Zealand until the implementation of Landonline (2000-2002). As Landonline was rolled out to each Land District, that district’s DCDB data was converted into the Landonline database (also known as the Core Record System or CRS) and then decommissioned. Unlike the prior systems, Landonline is 'live' and reflects real-time transactions as it enables surveyors, lawyers and other land professionals (including Territorial Authorities) to search and lodge title dealings and survey data digitally. New parcel shapes are therefore survey accurate. However as the change to parcels (attributes or shape) is mainly driven by the subdivision process, only a small portion of the parcels dataset will be changing at any given point of time.
