16 April 2020: Subsequent to publication in April 2019 we discovered two small errors with this dataset. These included:

  • Errors in the coordinates of some sites and their associated metadata (such as landcover and elevation).
  • Errors in our calculation of dominant landcover.

In addition, flow data from TopNet has also been updated.

These changes have a minor impact on overall results. These changes have have been corrected, and are republished here, as part of the Our freshwater 2020 release.

This dataset measures how water quality in New Zealand’s rivers is changing over time. It contains nine parameters of water quality based on measurements made at monitored river sites in years 1990-2017:

  • Nitrate-nitrogen
  • Ammoniacal nitrogen
  • Total nitrogen
  • Total phosphorus
  • Dissolved reactive phosphorus
  • Water clarity
  • Turbidity
  • Escherichia coli
  • Macroinvertebrate community index

More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.

This dataset was first added to MfE Data Service on 07 Apr 2020.

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 (1999–2018) periods.
