The air pollutant emissions indicator reports on national human-generated (anthropogenic) emissions of particulate matter (PM10 – particles smaller than 10 micrometres and PM2.5 – the subset of PM10 particles that are smaller than 2.5 micrometres), nitrogen oxides (NOx), carbon monoxide (CO), and sulphur dioxide (SO2), between 2012 and 2019. The grouped...

Inhaling particulate matter (PM) containing heavy metals can cause serious health effects (World Health Organization (WHO), 2013). Airborne arsenic is linked to lung cancers (WHO, 2013), and heart, liver, kidney, and nerve damage (Caussy, 2003). Nickel and vanadium are linked to lung and nasal sinus cancers. Lead can impair cognitive function in children...

Data are for 15 measures of coastal water quality at monitored sites in New Zealand. These 15 measures are dissolved oxygen, pH, salinity, temperature, visual clarity, turbidity, suspended solids, ammoniacal nitrogen, nitrate-nitrite nitrogen, total nitrogen, dissolved reactive phosphorus, total phosphorus, faecal coliforms, enterococci, and...

Annual rainfall trends for 30 representative sites from 1960–2016. Rain is vital for life – it supplies the water we need to drink and to grow our food, keeps our ecosystems healthy, and supplies our electricity. New Zealand’s mountainous terrain and location in the roaring forties mean rainfall varies across the country. Changes in rainfall amount or...

PM2.5 is made up of solid and liquid particles in the air with a diameter of less than 2.5 micrometres. In New Zealand, most PM2.5 in the air results from combustion (burning wood for home heating, motor-vehicle exhaust), and to a lesser extent, particles formed from reactions in the atmosphere (secondary PM) and naturally occurring sea salt. Short- and...

Trends in 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...

The trends in the number of warm days for the 30 temperature sites across New Zealand are presented from 1972 to 2022. Warm days are days with a daily maximum temperature above 25 degrees Celsius. The number of warm days change from year to year in response to variable weather patterns and climate drivers. Climate models project we may experience more...

Two measures of rainfall intensity - percent of annual precipitation in the 95th percentile (r95ptot) and annual maximum one-day rainfall (rx1day). 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...

The number of farms involved in agricultural activities, and how they are changing, is important because agricultural activities can affect soil health and water. Agricultural activities include beef and sheep, dairy, arable, horticulture, deer, pigs, and other livestock.

Black carbon is a particle, often in the PM2.5 or ultra-fine size range, which is emitted from combustion sources and is commonly known as soot. In New Zealand most black carbon is emitted from vehicles (especially diesel vehicles), burning wood and coal for home heating, and outdoor burning. Both long and short-term exposure to black carbon is linked to...

This indicator measures groundwater quality in New Zealand’s aquifers and how it is changing over time, based on measurements made at monitored sites. We report on nitrate-nitrogen, ammoniacal nitrogen, dissolved reactive phosphorus, chloride, conductivity and Escherichia coli (E. coli) including: trends in concentrations for 10-year (2009–18) and 20-year...

Influenza is a potentially life-threatening virus that spreads quickly from person to person. It is a significant public health issue in this country, with 10–20 percent of New Zealanders infected every year. While influenza can occur all year round, incidence generally peaks in winter and spring in New Zealand. Some studies suggest this is because the...
