Number of dredge tows (1990–2014)
Ministry for the EnvironmentSeabed trawling and dredging, when fishing nets or dredges are towed near and along the seabed, can physically damage seabed (benthic) habitats and species. It can also stir up sediment from the seabed, shading (in shallow waters) or smothering marine species. This measure focuses on coastal areas (waters shallower than 250m). Focusing on coastal benthic...Created 2 February 2020 • Updated 3 March 2025 -
Performance of assessed fish stock in relation to the hard limit (2009–15)
Ministry for the EnvironmentOur 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...Created 2 February 2020 • Updated 3 March 2025 -
PM10 exceedances by airshed 2006–13
Ministry for the EnvironmentParticulate matter 10 micrometres or less in diameter (PM10) in the air comprises solid particles and liquid droplets from both natural and human-made sources. PM10 can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (from vehicles). Natural sources of PM10 include sea salt, dust,...Created 2 February 2020 • Updated 3 March 2025 -
Lead concentrations 2005–13
Ministry for the EnvironmentLead is a heavy metal. Airborne sources include some industrial discharges, such as at metal smelters and the removal of lead-based paint from buildings without proper safety precautions. Lead can harm the nervous system and hearing, and impair mental development. Before 1996, when petrol became lead free, some New Zealand sites experienced elevated lead...Created 2 February 2020 • Updated 3 March 2025 -
Area of seabed trawled by depth class (1990–2011)
Ministry for the EnvironmentSeabed 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...Created 2 February 2020 • Updated 3 March 2025 -

Estimated fish and invertebrate bycatch in deep-water fisheries by year (1991–2012)
Ministry for the EnvironmentThe unintended catch of marine species other than the target species puts pressure on the populations of marine species by removing individuals or potentially modifying ecosystems.

Nitrogen dioxide concentration at state highway areas 2007–13
Ministry for the EnvironmentNitrogen dioxide (NO2) is a gas. It can be emitted directly into the air but is most often formed when nitric oxide (NO) emissions react with other chemicals in the air. Nationally, road motor vehicles are the main human-made source of nitrogen oxides (NOx, the collective term for NO2 and NO). NO2 may cause respiratory infections and reduced lung...Created 2 February 2020 • Updated 3 March 2025 -
Status of widespread indigenous trees - Widespread indigenous tree species,...
Ministry for the EnvironmentEight indigenous tree species, spanning a range of ecological niches, were surveyed twice (between 2002 and 2014) as part of a vegetation monitoring programme. The data from these surveys can be used to assess changes in tree populations. Monitoring the status and trends of these widespread tree species helps us detect large-scale, long-term changes and...Created 2 February 2020 • Updated 3 March 2025
