For trends, sites needed to have at least six complete years between 2011 and 2020. For annual trends, a site could not have a gap in the time series longer tan four months. Annual trends between 2011 and 2020 for: - Particulate matter 10 (PM10) concentrations - Particulate matter 2.5 (PM2.5) concentrations - Nitrogen dioxide (NO2) concentrations -...

This dataset measures the strength of extreme wind at 30 sites across Aotearoa New Zealand from 1980 to 2022. For individual sites, we provide data for the highest maximum wind gust, average maximum wind gust, and the number of days with wind gusts extreme for a location. The average of the daily maximum wind gust provides information on windiness, while...

We report on the conservation status and most recent change in status of indigenous (native), resident (breeds in New Zealand) marine species that have been assessed by New Zealand Threat Classification System (NZTCS) expert panels. This includes marine mammals (dolphins, whales, seals, and sea lions), seabirds and shorebirds, sharks, rays, and chimaeras...

This dataset measures daily rainfall at 30 sites across Aotearoa New Zealand from 1960 to 2022. Variables: site: location of monitoring station date: date rainfall: rainfall in mm rainfall_units: rainfall is measured in mm lat: Approximate latitude location of NIWA climate stations to represent a site. lon: Approximate longitude location of NIWA climate...

The Interdecadal Pacific Oscillation (IPO) is a long-term oscillation of sea-surface temperatures in the Pacific Ocean that can last from 20 to 30 years. Its positive and negative phases affect the strength and frequency of El Niño and La Niña. In New Zealand, the positive phase is linked to stronger west to southwest winds and more rain in the west. This...

We report on trends in nitrate-nitrogen from livestock that has leached from soil per year across New Zealand since 1990. Nitrogen is an essential nutrient for plant growth. It occurs naturally, but in agricultural systems more nitrogen is commonly added to soils as fertiliser or as urine or dung from livestock. Not all the additional nitrogen can be used...

Interpolated PED values at 30 regionally representative sites. Soil moisture is vital for plant growth. When plants cannot access the water they need, growth is reduced, affecting crops and food for livestock, and native biodiversity. Over a sustained period, a drought can have significant social and economic costs, particularly for rural communities....

Mast-seeding events occur when plant species (eg New Zealand flax or trees such as the beech species) produce very large amounts of seed, usually every 4–6 years. These events are vital for the survival of some indigenous bird species. Unfortunately, the increase in food supply also prompts a dramatic increase in the numbers of mice, rats, and stoats (a...

Irrigation is used to support land use, particularly in areas with low or seasonal rainfall. Irrigation can improve the productivity of land for farming activity, and support amenity or recreational land uses within urban environments.Irrigation can also alter the natural character of our landscapes (eg change dry land to greener and wetter land), and can...

This dataset measures annual and seasonal rainfall at 30 sites across Aotearoa New Zealand from 1960 to 2022. We also provide data for annual and seasonal anomalies (difference from baseline) for each site from 1960 to 2022. Variables: site: NIWA climate site. season: Season or Annual data (combined for ease of data use) precipitation: Rainfall in mm...

This dataset reports the annual and seasonal temperatures at 30 sites around the country from at least 1972 to 2022. Data are also provided on anomalies for all 30 stations (difference from the 1991–2020 baseline period) and for 16 stations (difference from the 1961–1990 baseline period). Variables: site: NIWA monitoring site statistic: Statistic: maximum...
