The Land Use Map is composed of New Zealand-wide land use classifications (12) nominally at 1 January 1990, 1 January 2008, 31 December 2012 and 31 December 2016 (known as "1990", "2008", "2012" and "2016"). These date boundaries were dictated by the First and Second Commitment Periods of the Kyoto Protocol. The layer can therefore be used to create either a 1990, 2008, 2012 or 2016 land use map depending on what field is symbolised.

The New Zealand River Environment Classification (REC) organises information about the physical characteristics of New Zealand's rivers. Individual river sections are mapped according to physical factors such as climate, source of flow for the river water, topography, and geology, and catchment land cover eg, forest, pasture or urban. Sections of river that have similar ecological characteristics can then be grouped together, no matter where they are.

This information is mapped for New Zealand's entire river network - over 425,000 kilometres of river. Different types of rivers respond differently to the pressures placed on them - the REC can be used to highlight the most appropriate management tools and approaches to reduce these pressures for each river type. Information from the classification is used to develop policy, assess the environment, and report on the quality of river water.

Stream order is the numerical position of a tributary or section of a river within the entire network. Headwater streams are assigned a stream order of 1. When two tributaries of the same stream order meet, the order increments by one for the next section downstream. However, if two sections meet where one section has higher order than the other, the next section downstream has the same order as the highest upstream section.

The REC groups rivers and parts of river networks that share similar ecological characteristics, including physical and biological. Rivers that share the same class can be treated as similar to one another and different to rivers in other classes. The REC classification system groups rivers according to several environmental factors that strongly influence or cause the rivers’ physical and ecological characteristics (climate, topography, geology and land cover). A catchment is a polygon that defines the upstream watershed of a river system or sub-system. Land cover within the catchment was used to populate the river classification factors (see table 1.1 of the User Guide data.mfe.govt.nz/document/123-rec-user-guide-2010/ ).

Coastal hydrosystems describe coastal features that span a gradient from near coast freshwater lakes/wetlands (lacustrine/palustrine environments) to marine. The term 'coastal hydrosystem' avoids the common error of referring to all such features as estuaries, mislabelling the numerous types that are non-estuarine and have different behavioural characteristics and management sensitivities from any truly estuarine environment. It also encompasses the coastal systems that do not represent end-of-river environments (e.g., some pocket beaches and embayments) or are so large and complex as to be fed by several freshwater drainage features (rivers, streams, wetlands) but which are dominated by none (e.g., some harbours, fjords, sounds and coastal-lacustrine systems). It also incorporates the multiple aspects of each system, including beaches, spits, barriers, river mouths, wetlands, saltmarshes and other geomorphic, ecological and hydrological features.

The New Zealand Coastal Hydrosystem classification (NZCH) is a classification of coastal hydrosystems within New Zealand including some offshore islands. The coastal hydrosystems classification is based on a hierarchical view of the abiotic components that comprise the environments of coastal hydrosystems. This classification presents detail at the geomorphic class level because this level is particularly important for coastal management and conservation needs at national and regional scales.

The primary GIS is the point layer. Supporting files (attached) include: a CSV database of environmental variables; GIS polygon layer; and Google Earth (.kmz) point and polygon exports.

The database, GIS and Google Earth files should be used in conjunction with the Classification of New Zealand's Coastal Hydrosystems report (Hume et al. 2016) (also attached) which documents a full description of the database, the calculation procedures and limitations to the variables.

The spreadsheet comprises a database of 500 New Zealand coastal hydrosystems and their associated environmental variables developed for the report.

The GIS point file comprises 500 New Zealand coastal hydrosystems and their associated environmental variables developed for the database. The environmental variables are mapped at 1:50,000 scale.

NOTE: Within the point attribute file -9999 represents the environmental variables with no data as shown in the spreadsheet as a blank cell. Make sure to exclude these values from analyses.

The polygon files comprise 420 New Zealand coastal hydrosystems depicting their general shape of the water body basin at high tide and upstream limit.

The .kmz files are derived from the NZCH GIS point and polygon layers for use with Google Earth.

The report provides a classification of coastal hydrosystems within New Zealand including some offshore islands. The coastal hydrosystems classification reconciles and clarifies coastal hydrosystem terminology and produces a hierarchy and classification of coastal wetland, riverine, estuarine and marine types. This report identifies and provides a list of environmental variables that describe the characteristics and properties of about 500 discrete coastal hydrosystems that can be used to provide national and regional statistics on coastal hydrosystems. An Identification Key is provided to guide the determination of the classes.
