Manawatū-Whanganui Data

This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.

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

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 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

Orthophotography within the Manawatū-Whanganui Region captured in the flying season of 2022-2023. Coverage encompasses Whanganui urban areas.

Imagery was captured for Whanganui District Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.

Data comprises:
• 896 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:1000 tile layout.
• Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. Please refer to the tile index layer for specific details, naming conventions, etc.

Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 at 95% confidence level in clear flat areas.

Index tiles for this dataset are available as layer Whanganui 0.075m Urban Aerial Photos Index Tiles (2022)

Index Tiles ONLY, for actual orthophotos see layer Whanganui 0.075m Urban Aerial Photos (2022)
