This layer provides the **current** non primary linear parcels (e.g. Centreline easements) and their associated descriptive data as a single layer to facilitate their use independently of other non primary parcels.
Linear parcels are non-primary parcels that are defined by a line and a description e.g. the width. The most common example is centreline easements (in gross) e.g. Pipeline easements.
If you require approved or historic linear 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 predecessor departments have been responsible for cadastral data in New Zealand for more than a hundred years.
Non Primary Parcels (e.g. easements) are drawn by surveyors on the various survey plans and diagrams along with the primary parcels.
Prior to LINZ, non primary 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, nor were they captured for the subsequent Digital Cadastral Database (DCDB).
When Landonline was rolled out (2000-2002) non primary parcels began to be captured on an ad-hoc basis. However it wasn't until the second major update of Landonline (CRS3) in 2008, that capture for all new non-primary parcels became mandatory (although non primary parcel capture became more common from approximately 2005 with CRS2.
A change in the ‘2010 Cadastral Rules for Survey’ now means that new non-primary parcels are not allowed to cross primary parcel boundaries.
