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. Freshwater plant pests can cause economic losses through blocking water intakes for hydroelectricity generation, impeded drainage or irrigation. In addition,...Created 2 February 2020 • Updated 3 March 2025 -
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. This dataset relates to the "Change in glacier...Created 2 February 2020 • Updated 3 March 2025 -
Notified cases of salmonellosis (1997–2013)
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. Monitoring the incidence rates...Created 2 February 2020 • Updated 3 March 2025 -

Sea-bird fishing-related mortality by conservation status (2006/7 to 2012/13)
Ministry for the EnvironmentAlong with sea lions, fur seals, and dolphins, seabirds are the protected species most directly affected by fisheries in New Zealand waters. Reporting on the risk of threatened and at-risk seabirds dying as a result of fishing activities each year is one way of assessing the pressure some seabird species face from current fishing practices. This dataset...Created 2 February 2020 • Updated 3 March 2025 -
Daily average column ozone by DOY (1978–2013)
Ministry for the EnvironmentOzone (O3) is a gas that is of interest in two regions of Earth’s atmosphere – at ground level and in the upper atmosphere (stratosphere). Stratospheric ozone absorbs ultraviolet (UV) rays from the sun and protects Earth from harmful levels of UV. Exposure to these UV rays has been linked to skin cancer. Monitoring variations in stratospheric ozone...Created 2 February 2020 • Updated 3 March 2025 -
Macroinvertebrate Community Index trends, by monitoring site, 2004-13
Ministry for the EnvironmentBenthic macroinvertebrates are small animals without backbones (eg insects and worms). They live on and under submerged logs, rocks, and aquatic plants on the beds of rivers and streams during some part of their life cycle. Macroinvertebrates play a central role in stream ecosystems by feeding on periphyton (algae), macrophytes (aquatic plants), dead...Created 2 February 2020 • Updated 3 March 2025 -
Frost and warm days trend assessment, 1972–2016
Ministry for the EnvironmentThe number of frost and warm days changes from year to year in response to climate variation, such as the warming pattern induced by El Niño. Climate models project we may experience fewer cold and more warm extremes in the future. Changes in the number of frost and warm days can affect agriculture, recreation, and our behaviour, for example, what we do...Created 2 February 2020 • Updated 3 March 2025 -

Conservation status of shorebird species and subspecies (2012)
Ministry for the EnvironmentNew Zealand has 92 seabird and 14 shorebird species and subspecies (taxa). Seabirds and shorebirds tend to be at or near the top of the food chain, and thrive only if the marine ecosystem is healthy. Decreasing bird populations can signal that the ecosystem is degrading.

High-class land for food production - New urban area on high-class land, by...
Ministry for the Environmenthigh-class land is the most productive land for growing food. It supports most crops across New Zealand. Expanding lifestyle blocks and urban areas reduces the availability of high-class land for commercial crop growing, and this land is unlikely to be returned to primary production. This affects our commercial food-production capacity. Column headings:...Created 2 February 2020 • Updated 3 March 2025
