We have clean water, fresh air and healthy soils. Well-functioning and diverse ecosystems make up an environment that can support our needs. Resources are used efficiently. There is minimal waste and pollution.
Good air, water and soil quality, and reducing waste are all essential to maintaining a healthy environment and ensuring the sustainability of resources. Water-based recreational activities are part of an outdoor-focused way of life and it is essential that the water is of a high quality. Protecting land through open space covenants also helps maintain ecosystem diversity, along with natural and cultural heritage. Primary land uses such as agriculture, dairying and cropping are key contributors to an economy but they can have a negative influence on the environment.
16 indicators are used to measure progress towards the healthy environment outcome (defined above). Data relating to each individual indicator (for the 2001 to 2018 period) is provided via the menu below. The healthy environment index (pictured below) shows the composite average of the individual indicators.
As there is only one community outcome under environmental well-being, the same index is applied to both the well-being aspect and the community outcome area.
The GPI counts crime, pollution, greenhouse gas emissions, natural resource depletion and soil loss, as costs, not gains, to the economy.

Nitrate is a commonly measured indicator of groundwater quality. Compliance with the national standard should ensure that it is safe for the water to be used for human (and stock) consumption. Elevated nitrate concentrations may indicate a health risk as well as a risk of adverse impacts on the water quality in rivers and lakes, and in freshwater ecosystems. Greater Wellington Regional Council uses a threshold of less than 3mg/L of nitrate (measured as nitrate nitrogen) as their indicator of good water quality.
The number of groundwater monitoring sites that have median nitrate concentrations in the <0.002-3.0mg/l range expressed as a function of the total number of groundwater sites monitored

Data available only for 2007 to 2018
Only selected sites around the region are monitored, and the number of sites monitored has changed over the study period. Groundwater quality, particularly in shallow aquifers, is also strongly influenced by rainfall and river flows.

Indicators are updated in May and November each year; for those indicators where new data or survey results have become available.
