Performance of assessed fish stock in relation to the soft 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 -
Recruitment of indigenous tree sp putaputawēta 2002–2014
Ministry for the Environment"The rates of establishment (recruitment) of indigenous tree species vary across New Zealand. Changes in the state of the environment (such as from browsing pests, large-scale weather events, or climate change) may change the rates of recruitment of particular tree species. This in turn may alter forest processes. Repeated surveys of the distribution of...Created 2 February 2020 • Updated 3 March 2025 -
Estimated forest carbon stocks - Change in forest carbon stocks, 1990–2012
Ministry for the EnvironmentNew Zealand’s indigenous and exotic forests absorb and store carbon from the atmosphere through photosynthesis. As forests grow, the carbon stored in them increases. These carbon stocks help offset greenhouse gas emissions from sources such as agriculture, energy production, and transport. Column headings: type = vegetation type of forest vol_tC = volume...Created 2 February 2020 • Updated 3 March 2025 -

Estimated global production of major ozone-depleting substances (1986–2013)
Ministry for the EnvironmentOzone in the stratosphere is destroyed in a catalytic reaction with a range of chemical species (mainly CFCs) that are emitted through human activities. The emission of these ozone-depleting substances (ODSs) is closely related to the amount of the chemicals that are produced. The ozone layer absorbs most of the sun's harmful ultraviolet (UV) radiation....Created 2 February 2020 • Updated 3 March 2025 -

Cumulative occupancy of key non-indigenous species by port of first entry (2009–2015)
Ministry for the EnvironmentMarine non-indigenous (exotic) species arrive in New Zealand waters on the hulls of international vessels (biofouling) or in discharged ballast waters. Some have little impact or cannot survive in New Zealand waters; others have a negative impact on our native habitats and species and become pests. They can compete with, and prey on, indigenous species,...Created 2 February 2020 • Updated 3 March 2025 -
Carbon monoxide concentrations and exceedances 2005–2013
Ministry for the EnvironmentCarbon monoxide (CO) is a gas formed by incomplete combustion of fuels, in particular from road motor vehicles and burning wood and coal for home heating. It also occurs naturally, for example, from wild fires. CO can affect human health by interfering with the blood’s ability to carry oxygen and by aggravating heart conditions. Road motor vehicles are...Created 2 February 2020 • Updated 3 March 2025 -
Ozone hole (1979–2014)
Ministry for the EnvironmentOzone protects the Earth from harmful levels of UV radiation. The ozone hole is an area of reduced stratospheric ozone that forms over Antarctica each spring, due to ozone-depleting substance. Reporting on the state of the ozone hole provides important context for the state of ozone concentrations globally.

Freshwater pests: Canadian pondweed
Ministry for the Environment"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.

Annual glacier ice volumes (1978–2014)
Ministry for the EnvironmentA glacier is a body of slow-moving ice, at least one hectare in area that has persisted for two decades or longer. Glacier volume is strongly influenced by climate factors, such as temperature and precipitation. Changes in glacier ice volumes give some indication of changing climate conditions in New Zealand.

Ministry for the EnvironmentBacteria and parasites like campylobacter, salmonella, and cryptosporidium can contaminate our food and water, leading to serious illness. Campylobacter, salmonella, and cryptosporidium are influenced by temperature and other climate variables, and incidence rates may increase as climate change causes temperatures to rise.
