11 June 2021: A revised version of this dataset has been published to correct the terminology used to compare nitrate-nitrogen values to the 3 g/m3 guideline value. The field name has been changed from “ref_meet” to “n_n_guideline”, and values in this field will now be either “Does not exceed” or “Exceeds”, instead of “Meets” or “Does not meet”. ​ This...

"Freshwater plant and animal pests can have significant negative impacts on ecosystem health by reducing indigenous biodiversity through predation and competition, and destabilising aquatic habitats. Freshwater plant pests can cause economic losses through blocking water intakes for hydroelectricity generation, impeded drainage or irrigation. In addition,...

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...

Sea lions and fur seals are the protected species most directly affected by fisheries in New Zealand waters, along with seabirds and dolphins. Trawling poses a risk to both species. Fur seals can also be captured by other fishing gear, including long lines. Estimating the bycatch of sea lions and fur seals indicates the pressures they face from current...

The marine economy shows the contribution marine-based economic activities make to the New Zealand economy as measured by gross domestic product (GDP). Measuring the marine economy shows how New Zealand’s marine environment is used to generate economic activity and how this changes over time. However, these activities can also be a source of pressure on...

Skin cancers such as melanoma are linked to exposure to ultraviolet radiation. New Zealand has one of the world’s highest rates of melanoma. This dataset relates to the "Occurrence of melanoma" measure on the Environmental Indicators, Te taiao Aotearoa website.

Flow is the volume of water passing a point over a certain time, and provides information about the availability of water for people and the environment. Overall, this affects how much water is available for irrigation, drinking water, hydroelectricity generation, and recreational activities. River flows also influence a waterway’s physical form, habitat,...

Seabed trawling and dredging (where fishing gear is towed near or along the ocean floor) can physically damage seabed (benthic) habitats and species. These fishing methods can also stir up sediment from the seabed, creating sediment plumes that can smother sensitive species. Recovery times for affected habitats and species depend on their sensitivity and...

New Zealand’s fisheries and aquaculture sector is an important primary industry. It provides New Zealanders with food, economic returns, and employment. Reporting on the value of this industry helps us to understand the marine economy. This dataset relates to the "Value of fisheries and aquaculture" measure on the Environmental Indicators, Te taiao...

New Zealand has 92 seabird and 14 shorebird species and subspecies (taxa). We have the highest number of endemic seabirds (found only in a particular area) in the world. Nearly 25 percent of the world’s seabird species breed in the New Zealand region, and almost 10 percent only breed here. Seabirds and shorebirds tend to be at or near the top of the food...

NIWA supplied ozone data in two forms, with different starting dates: - measurements made using a Dobson spectrophotometer (number 72), from 1987 - data assimilated from satellite measurements recalibrated against the global Dobson network, from 1978. NIWA takes measurements using the Dobson spectrophotometer 72 under clear-sky, direct sunlight conditions...

PM2.5 are particles 2.5 micrometres or less in diameter. PM2.5 is emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (eg from vehicles). Natural sources have less influence on PM2.5 concentrations than PM10 concentrations. This means PM2.5 comes mainly from human activities. Nationally,...
