New Zealand National and Regional State of the Environment Aquifer Reporting

Central and regional government agencies collaborate to monitor and report on the quality of New Zealand's groundwater resources. Measurements from around 1,100 water wells representing the main economic aquifers are collected each season and used to prepare regional or national reports on its state, and trends over time. New Zealand's groundwater quality is of a relatively high standard by international standards, but is influenced by human activities and can also be affected by naturally occurring degrading processes.
