Spatial Parcel Improvement Project
The Spatial Parcel Improvement (SPI) Project, begun mid-2010, is a two year project to capture and adjust survey data from existing survey plans to improve the accuracy of the cadastre in high priority areas.
The project's initial focus is on selected urban and rural areas of intensive use, with an aim to have 95% of coordinates in these areas accurate to two metres.
Read more about the project in the June 2010 news release and about the accuracy of the digital cadastre.

Suggest areas for improvement
LINZ welcomes suggestions on areas where existing survey data could be improved. In particular, LINZ is interested in urban areas and intensively used rural areas where cadastral data is inaccurate.
To suggest an area for improvement, use the online SPI recommendation form or email spiproject@linz.govt.nz.
If suggesting an area by email, please attach an image showing the extents of the area and include a brief reason for the recommendation. The following file extensions are accepted: shp, kml, tab, tiff, jpeg (note: please ensure shape files are zipped. The zip file must be password free).
