Ozone is a gas that forms a naturally occurring layer in the upper atmosphere (stratosphere), protecting Earth from the sun’s ultraviolet (UV) light. The ozone hole is an area of reduced stratospheric ozone. It forms in spring over Antarctica because of ozone-depleting substances (ODSs) produced from human activities. The ozone hole has started to shrink due to the phase-out of ODSs, and it is possible that it will cease to form by the middle of this century.
The ozone hole does not have a large effect on the concentration of ozone over New Zealand. However, when the ozone hole breaks up in spring, it can send ‘plumes’ of ozone-depleted air over New Zealand. Reporting on the state of the ozone hole helps us understand the state of ozone concentrations globally.

An emissions inventory provides information on the amount of key air pollutants that are released into the atmosphere for a given location over a given time period. This enables us to identify sources of pollutants. By understanding the amounts that different sources contribute, air quality can be better managed and modelled.
We evaluated emissions for five key pollutants for 2015, the most-recent year that data were readily available: particulate matter (PM) less than 10 micrometres in diameter (PM10), PM less than 2.5 micrometres in diameter (PM2.5), carbon monoxide (CO), nitrogen oxides (NOx), and sulphur dioxide (SO2), because they are the most important pollutants in New Zealand.
The grouped sources include: energy-related activities, construction dust, road dust, industrial process emissions (non-combustion), agriculture (emissions from animal housing), vegetation fires (burning agricultural residue and biomass burning), and incinerating of hazardous waste.
Only human-generated emissions were included in this emission inventory. No updated data for residential wood burning were available and was assumed to be the same as the 2013 national inventory.

"This data identified areas in the South Island that have been classified as being the most productive for growing food. It supports most crops across New Zealand. Expanding lifestyle blocks and urban areas reduce 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.

This data set relates to the "High-class land for food production" measure on the Environmental Indicators, Te taiao Aotearoa website."

Land cover describes the extent of vegetation, water bodies, built environments, and bare natural surfaces (eg gravel and rock) across New Zealand. Measuring the composition of and changes in land cover can help us understand the pressures that different land uses are placing on the biodiversity and functioning of ecosystems.

This measure reports on land cover by class, regional council area, and change over time in hectares and percentage.

New 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 covered by these tools as an indirect measure to understand the state of the marine environment.
Marine reserves lie within our territorial sea (12 nautical mile limit) and offer the highest level of marine protection in New Zealand waters. No marine habitat or life form, such as seaweed or fish, may be removed from, or disturbed in, these places.

New Zealand has a diverse range of marine mammal species. Marine mammals are indicator species for the state of our marine environment. They are apex species (near the top of the food chain) and can thrive only if their ecosystems are healthy. A decreasing population can indicate that the ecosystem is degrading.
This dataset relates to the "Conservation status of marine mammals" measure on the Environmental Indicators, Te taiao Aotearoa website.

Growing degree days (GDD) is the measure of how much warmth is available for plant and insect growth during a growing season. GDD information helps horticulturists and farmers predict plant growth and stock development. The GDD value changes in response to climate variations, such as El Niño. Long-term changes in GDD are a measure of changing climate conditions.

"The pressure from animal and plant pests is one of the biggest threats to biodiversity in the land environment. Pest predators (such as stoats and possums) eat eggs, birds, lizards, insects, and snails. Other animal pests (such as deer and goats) damage and kill trees and other plants and can compete with indigenous animals for the plants’ fruit and seed. Pest plants can out-grow the local vegetation. All these activities can dramatically change both our indigenous and agricultural environments.

This data set relates to the "Land pests" measure on the Environmental Indicators, Te taiao Aotearoa website."
