Temperature at 30 sites around the country from at least 1972 to 2022. We report annual and seasonal trends for the period 1972 to 2022 as well as rate of temperature change per decade. We provide data on average, minimum, and maximum for daily, annual, and seasonal temperatures. Trends are reported for annual and seasonal statistics. Temperature change...

For seasonal trends, sites needed to have at least six complete seasons between 2011 and 2020. New to this update: not all seasons had to be complete – the previous update only calculated trends over complete seasons. Seasonal trends between 2011 and 2020 for: - Particulate matter 10 (PM10) concentrations - Particulate matter 2.5 (PM2.5) concentrations -...

Daily peak UV index values at Invercargill, Lauder (Otago region), Christchurch, Paraparaumu (Wellington region), and Leigh (Auckland region). The strength of UV light is expressed as a solar UV index, starting from 0 (no UV) to 11+ (extreme). Exposure to the sun's ultraviolet (UV) light helps our bodies make vitamin D, which we need for healthy bones and...

This dataset reports the linear trend (downward or upward shifts in data points over time) in New Zealand’s national average temperature from 1909 to 2022 from the National Institute of Water and Atmospheric Research’s (NIWA) ‘seven-station’ temperature series. Variables: data_released: Year the data was released source: Source of data p_value: P value...

Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency. Dataset used to develop the "River water quality: Escherichia coli" indicator (available at https://www.stats.govt.nz/indicators/river-water-quality-escherichia-coli). This dataset contains one parameter of water quality based on...

Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency. Dataset used to develop the "River water quality: clarity and turbidity" indicator (available at https://www.stats.govt.nz/indicators/river-water-quality-clarity-and-turbidity). This dataset contains two parameters of water quality based...

We provide temperature and anomaly data alongside Intergovernmental Panel on Climate Change (IPCC) global land temperature anomalies against the 1961 to 1990, and 1991 to 2020 baseline periods. Global average temperatures have increased by around 1 degree Celsius in the last century, almost certainly a result of high levels of atmospheric greenhouse gases...

This layer is the total rainfall for the year 2016, summed from interpolated daily rainfall, in mm, not the average. ​ More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.

Carbon monoxide (CO) is a gas formed by the incomplete combustion of fuels, particularly from motor vehicles, from burning wood and coal, and using unflued gas heaters for home heating. It also occurs naturally; for example, from wild fires. Carbon monoxide can affect human health by interfering with the blood’s ability to carry oxygen and by aggravating...

Carbon monoxide (CO) is a colourless, odourless and tasteless gas. The most common sources of carbon monoxide are from the incomplete combustion of fossil fuels such as fuel used by vehicles, and from wood and coal, commonly burnt in fires for home heating. Other common sources of carbon monoxide are tobacco smoke and indoor gas fires. It also occurs...

We report on the conservation status and most recent change in status of indigenous (native), resident (breeds in New Zealand) freshwater fish and invertebrates that have been assessed by New Zealand Threat Classification System (NZTCS) expert panels. More information on this dataset and how it relates to our environmental reporting indicators and topics...

This metadata record describes an image of land predicted to be at risk of severe mass movement erosion for the South Island. The image was produced using the Highly Erodible Land model that identifies land at risk to the main forms of mass-movement soil erosion in New Zealand: landsliding, gullying, or earthflow erosion. If the land has protective woody...

Forest carbon stocks and areas, including stock changes, areas, and deforestation. New Zealand’s indigenous and exotic forests absorb carbon dioxide (CO2) from the atmosphere through photosynthesis and store the carbon as biomass and in the soil. On average, more than twice as much carbon per hectare is stored in New Zealand’s mature indigenous forests...

Note that this is a large dataset so is provided as a shapefile, and will need a GIS application to view. Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency. Dataset used to develop the "River water quality: phosphorus" indicator (available at https://www.stats.govt.nz/indicators/river-...

The resource management enforcements dataset is compiled, from data supplied by Local Authorities (Regional, Unitary, and Territorial Councils), by the Ministry for the Environment. It contains numbers of different types of enforcement actions required of local authorities from 2014/15 to 2022/23. The NMS monitors implementation of the RMA by local...

Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency. Dataset used to develop the "Lake water quality" indicator (available at https://www.stats.govt.nz/indicators/lake-water-quality). We report on eight biological, chemical, and physical lake water quality attributes based on measurements...

This indicator measures the thickness of total column ozone in Dobson Units (DU) observed above Lauder, Otago, by day of year from 1979 to 2022. Variables: date: The date of the observation in YYYY-MM-DD total_colum_ozone: The thickness of the Total Ozone Column (TOC) in Dobson Units conf_low: Provides a lower limit to the uncertainty associated with the...

Lightning is the discharge of electricity from thunderstorms and can occur within a cloud, between clouds, or between a cloud and the ground. By international standards, lightning does not occur frequently around New Zealand. However, ground strikes can injure or kill people and livestock, damage property and infrastructure, and, although rarely in New...

Trends in percent of annual rainfall in the 95th percentile (r95ptot), 1960–2016. Intense rainfall can result in flash floods or land slips that damage homes and property, disrupt transportation, and endanger lives. It can also interfere with recreation and increase erosion. Changes to the frequency of intense rainfall events can alter biodiversity. Trend...
