The New Zealand Land Resource Inventory (NZLRI) is a national database of physical land resource information. It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work:

1. An inventory of five physical factors (rock type, soil, slope, present type and severity of erosion, and vegetation). A 'homogeneous unit area' approach is used to record the five physical factors simultaneously to a level of detail appropriate for presentation at a scale of 1:50,000.
2. A Land Use Capability (LUC) rating of the ability of each polygon to sustain agricultural production, based on an assessment of the inventory factors above, climate, the effects of past land use, and the potential for erosion. The NZLRI covers the country in 11 regions, each with a separate LUC classification.

The first edition NZLRI provides national coverage from mapping between 1973 and 1979 at a scale of 1:63,360. A limited revision regional upgrade of the north Waikato area was completed at a scale of 1:63,360 in 1983. Second edition NZLRI regional upgrades at a scale of 1:50,000 have been completed for Northland, Wellington, Marlborough and Gisborne-East Cape. Third edition NZLRI layers contained a restructured polygon attribute table to allow the core NZLRI to complement the newly created fundamental soil layers with minimal duplication.

Update of Edition 3 NZLRI. This update involves ++**no new mapping**++, but does include a ++**new National Land Use Capability legend**++ correlated for all regions across New Zealand. Attributes include original LUC units codes and unit descriptions so that users more familiar with original regional codes and North Island correlations can track the pedigree of units from old to new codes and descriptions.

The NZLRI is a spatial database containing about 100,000 polygons (map units), each of which describes a parcel of land in terms of five characteristics or attributes (rock, soil, slope, erosion, vegetation). This layer represents a GIS dissolve on the soil attribute of the NZLRI.

The land overlays are developed from amalgamated units from the land use capability (LUC) assessment of the New Zealand Land Resource Inventory (NZLRI) Gisborne East Coast Region, Second Edition, June 1999. In the NZLRI the maximum erosion severity has been assessed for each LUC unit and this is based on the geology, soil type, steepness, climate and vegetation cover. The land overlays comprise the following LUC units: Land Overlay 1 Classes I-IV and VIe1, 2, 3, 5, 7 and 8 inclusive, Land Overlay 2 Balance of Class VI, Land Overlay 3 (including 3A) Classes VII & VIII (see C7.1.5 for detailed units).

Erosion is the natural process of soil and rock wearing away and being moved through the landscape. Erosion includes sheet, wind, creep, slump, flow, rill, earthflow, gully, tunnel gully and stream erosion. In areas undisturbed by human activity, the rate of erosion is determined by geology and weather. Land uses, particularly those that reduce vegetation cover or disturb the soil can lead to a much faster rate of erosion. This is especially heightened in naturally unstable areas where even relatively minor landuse activities can have major impacts. Erosion that has been increased by human action is called induced or accelerated erosion and despite the voluntary erosion control efforts of many landowners and kaitiaki, this remains the major landuse issue in the district that also impacts on the district’s waterways and coastal seabed and key assets such as roading.

The New Zealand Fundamental Soil Layer originates from a relational join of features from two databases: the New Zealand Land Resource Inventory (NZLRI), and the National Soils Database (NSD). The NZLRI is a national polygon database of physical land resource information, including a soil unit. Soil is one in an inventory of five physical factors (including rock, slope, erosion, and vegetation) delineated by physiographic polygons at approximately 1:50,000 scale. The NSD is a point database of soil physical, chemical, and mineralogical characteristics for over 1500 soil profiles nationally. A relational join between the NZLRI dominant soil and derivative tables from the NSD was the means by which 14 important soil attributes were attached to the NZLRI polygons. Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layers contains flood return interval attributes. The classes originate from and are described more fully in Webb and Wilson (1995).

Data has been created from hosted feature service (https://mapping.gw.govt.nz/arcgis/rest/services/GW/NRPMap_P_operative/MapServer). It has been shared to the Open Data Portal. Map of lowland areas for category 2 surface waterbodies in the Wellington region for the management of rivers and streams in productive rural lowland areas.This feature class is derived from the New Zealand Land Resource Inventory (NZLRI) and the Land Cover Database v4 (2012), both produced by Landcare Research - Manaaki Whenua.In particular it is based on the land use capability layer which makes an assessment of the productive capability of land areas based on the underlying geology, soil type, slope angle, erosion susceptibility and vegetative cover.Slope classes A, B & C (under 16 deg) and soil classes 1-4 (arable land) were classified for inclusion in the area. Slope classes D,E, F & G (over 16 deg) and soil classes 5-8 (non-arable land) were excluded.It was created by first eliminating discrete polygons with slope classes below 15 degrees, occurring within broader areas above 16 degrees, using the dissolve tool. Likewise, islands of land over 16 degrees smaller than 15 km2sitting within lowland areas under 16 degrees were eliminated. Then complex, crenulated areas were rounded off with the simplify and smooth polygon tool. The whole delineation was then checked for accuracy and aligned where necessary to conform to slopes under 16 degrees with arable soils classes four and under.

Service Description: Hinterland characteristics – describes the nature of the hinterland with respect to its geomorphology and topography. This variable has 7 attributes such as lagoons, plains, rising ground and sea cliffs. The geomorphic variables were sourced from the New Zealand coastal type classification scheme and GIS mapping procedures that were previously created for Coastal Explorer using advice from expert panels including regional council staff, knowledgeable locals, university staff and consultants from throughout New Zealand. The coast was mapped and referenced against panel knowledge using information from a wide variety of sources including: 1:50,000 topographic maps, aerial photographs, Google Maps and Google Earth, RNZN hydrographic charts, various publications and reports, New Zealand Land Resources Inventory (NZLRI), the National Land Cover Data Base (LCDB), and the Estuarine Environment Classification database. In assembling the coastal and beach type information, site visits were made to many beaches to obtain information that could not be collected from existing sources, and parts of the coast were flown by light aircraft to obtain oblique aerial photographs. https://gis.niwa.co.nz/server/rest/services/COAST/NZ_Coastal_classification_Hinterland_characterstics/MapServer_Item Page Created: 2017-06-15 00:33 Item Page Last Modified: 2025-04-05 18:48Owner: steinmetzt_NIWA

Maps produced for MethaneSAT. Each dataset is an estimate of methane produced by enteric fermentation across different classes of livestock at approximately 1.5 km resolution (pixel length); this is not an equal area projection. Datasets are 12-band raster data where each band is monthly emissions (1=January). "CCTO", "CCPO" and "CCAV" refer to values of livestock carrying capacity determined by the NZLRI. The data underlying these maps are livestock distribution maps at sub-farm scale. Methane emissions are estimates based on Tier 2 inventory accounting methods. Distributions of livestock are determined through a process that combines Agribase farm counts, pasture productivity and the agricultural production surveys and census. A slightly more detailed methodology document is included as an attachment. Note that the output is considerably downsampled from sub-farm scale, using a weighted sum algorithm. This is both by necessity (to sufficiently confidentialise Agribase information), and by design (to match the resolution used in inverse modelling). Units are kT CH₄ (kilotonnes of methane), monthly total per pixel. Please acknowledge the funding from the NZ Space Agency through the MethaneSAT Project (C01X2023) which ultimately made this possible.

The Erosion Susceptibility Classification (ESC) is used to identify the susceptibility of land to erosion and then to set regulatory thresholds for various plantation forestry activities. The ESC is based on the analysis of potential and present erosion data associated with the NZ Land Resource Inventory and classification of Land Use Capability (LUC) units. This revision extends the ESC to cover all of New Zealand, revises the ESC class of some LUC units, allows identification of ESC units dominated by gully, tunnel gully and earthflow erosion, and identifies all polygons containing class 8e land.This dataset has been prepared to support the National Environmental Standard for Plantation Forestry. The ESC is used to identify the susceptibility of land to erosion which is used as the basis for setting resource consent requirements for various plantation forestry activities on different types of land. The ESC is based on the New Zealand Land Resource Inventory (NZLRI).
