Freshwater fish are an important component of freshwater ecosystems, have intrinsic biodiversity values and are a valued resource for Māori, recreational and commercial fishers. The presence or absence of a fish species can be affected by changes in catchment land cover and land use, in-stream habitat, fish passages (routes for moving up and down waterways), pests, and contaminants.

The file contains the information associated with each record in the New Zealand Freshwater Fish Database used in the report, and the associated River Environment Classification information of the location of the observation.

Dominant land uses in New Zealand include conservation (eg national and forestry parks), forestry (eg for timber resources/wood supply), urban (eg built up areas and open parkland), and agriculture and horticulture. Each land use places different pressures on the land and on receiving environments such as waterways. These pressures can be both positive (eg increased productivity) and negative (eg biodiversity loss and reduced functioning of ecosystems).

This measure reports on agricultural and horticultural land uses by region.

Regional councils issue resource consents for the taking of fresh water for various purposes, including irrigation, drinking, hydroelectricity, and industry. Water can be taken from surface water or groundwater.

The file provides the primary source and primary use of the water take for each consented take.

Livestock farming is a widespread land use in New Zealand and contributes to our economy. High livestock numbers and the distribution of livestock across land environments can affect indigenous biodiversity and soil health (eg compaction). High livestock numbers and density in some land environments can also affect water quality, as nitrogen and bacteria from urine and faeces can leach into groundwater or run off the land into rivers and lakes.

We measure changes in the numbers of farmed livestock (eg beef and dairy cattle, deer, and sheep) across regions in New Zealand.

New Zealand has a diverse range of freshwater species. Many of these species are endemic to (only occur in, or only breed in) New Zealand. Freshwater fish and invertebrates are indicator species for the state of our freshwater environment. A decreasing population can indicate that the ecosystem is degrading.

This measure reports on the conservation status of New Zealand's indigenous freshwater fish and invertebrate species, including the number of species that have had a genuine change in conservation status between two monitoring periods (2009–13 and 2005–13). A change in a species’ conservation status reflects a change in its risk of extinction.

River water quality is valued for many reasons including ecological function and habitat, recreational value, its role in supporting people and industry, and its cultural significance. Nutrients such as nitrogen and phosphorus are essential for plant growth, however too much in rivers can lead to excessive growth of river algae, which can degrade habitat.

High concentrations of nitrogen in the form of ammoniacal nitrogen and nitrate-nitrogen can be toxic to fish and other aquatic animals, and nitrate-nitrogen can be toxic to humans. Water clarity is a measure of underwater visibility, and affects habitat of aquatic life such as fish and birds, and can also impact on aesthetic values and recreational use of rivers and streams. Escherichia coli (E.coli) can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces, which can cause illness.

File contains the model outputs for river water quality indicators as medians for each river segment in New Zealand’s digital river network.

Livestock numbers reflect changes in the number of farmed beef and dairy cattle, deer, and sheep across New Zealand. Livestock farming is a widespread land use in this country. It is important to monitor livestock numbers, because concentrated numbers, or large increases in numbers, can affect the indigenous biodiversity, soil health, and water quality.

File contains total livestock numbers by region for each year over the period 1994–2015

New Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. We also have many marine species found only in New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area covered by marine reserves as an indirect measure to understand the state of the marine environment.

Our fish stocks are affected by commercial, customary, and recreational fishing, and environmental pressures (eg ocean temperature, acidity, and productivity). The Ministry for Primary Industries uses three performance measures to assess influences on fish stocks: a soft limit (below which a rebuilding plan is required), a hard limit (below which closing a fishery should be considered), and an overfishing threshold (where the rate of extraction is higher than the rate of replenishment).
