Cultural Health Index scores for waterways, 2005–16
Ministry for the EnvironmentCultural Health Index scores for a waterway is a combination measure of historical cultural use and access, mahinga kai assessment, and water quality assessment from a cultural perspective of a site on a waterway. The Cultural Health Index scores compile this information into a classification system to provide an overall grading of the state of a site and...Created 2 February 2020 • Updated 3 March 2025 -
Oceanic sea surface temperature anomaly
Ministry for the EnvironmentThe ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Sea surface temperature changes with climate drivers such as El Niño, and will change with climate change. The sea surface temperature anomaly provides an indication of the heat change in the...Created 2 February 2020 • Updated 3 March 2025 -
Conservation status of marine mammals
Ministry for the EnvironmentNew Zealand has a diverse range of marine mammal species and subspecies, including whales, dolphins, seals, and sea lions. Marine mammals are indicator species for the state of our marine environment. The conservation status of a species relates to its risk of extinction. Many of these species are endemic (only found in) to New Zealand. They are apex...Created 2 February 2020 • Updated 3 March 2025 -
Freshwater pests: Great pond snail
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 -
Natural river flow statistics, predicted for all river reaches
Ministry for the EnvironmentRiver flow is the quantity of water passing a point over a certain time. Each river or stream has its own natural flow characteristics, such as peak flows following rain or high spring flows from snow melt. Overall, this affects how much water is available for irrigation, drinking water, hydroelectricity generation, and recreational activities. River...Created 2 February 2020 • Updated 3 March 2025 -

BOMEC_15_Class_region
Ministry for the EnvironmentThe 15 class Benthic-Optimised Marine Environment Classification (BOMEC). The BOMEC divides the benthic environment into ecosystem types. These are grouped into three inshore groups, three continental shelf groups, and nine deeper-water groups. Each group represents areas with similar environmental variables, such as depth, temperature, salinity, and...Created 2 February 2020 • Updated 3 March 2025 -
Emissions from burning wood or coal for home heating 2006 and 2013
Ministry for the EnvironmentIn 2013, 37 percent of homes burned wood and 4 percent burned coal for heating. Burning wood or coal for home heating emits a range of air pollutants. It is the main human-made source of particulate matter and a significant contributor of carbon monoxide. Exposure to these pollutants can damage health, with effects ranging from respiratory irritation to...Created 2 February 2020 • Updated 3 March 2025 -
DoC marine mammal sanctuaries (2016 report)
Ministry for the EnvironmentNew Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to 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...Created 2 February 2020 • Updated 3 March 2025 -
Number of extreme wave events exceeding 4m in coastal regions, 2008–15
Ministry for the EnvironmentExtreme wave indexes estimate the occurrence of extreme wave events in coastal and oceanic waters. Extreme wave indexes estimate the number of times a significant wave height exceeds one of three threshold values for at least 12 hours in 24 marine regions. The three wave-height thresholds are four metres, six metres, and eight metres. This indicator...Created 2 February 2020 • Updated 3 March 2025 -
Estimated contemporary and pre-human wetland area, by region (2008 estimate)
Ministry for the EnvironmentWetlands support unique biodiversity and provide important services. They clean water of excess nutrients and sediment, help absorb floodwaters, and act as carbon sinks (remove carbon dioxide from the atmosphere). They also have cultural importance for Māori, and provide valuable food and materials (eg flax). Draining wetlands for agricultural and urban...Created 2 February 2020 • Updated 3 March 2025 -
Mortality of indigenous tree sp māhoe 2002–2014
Ministry for the Environment"The rates of death (mortality) 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 mortality of particular tree species. This in turn may alter forest processes. Repeated surveys of the distribution of mortality...Created 2 February 2020 • Updated 3 March 2025 -
