Report overview
  • Our National Policy Statement for Freshwater Management 2020 (NPS-FM) gives minimum acceptable levels of water contaminants. Throughout New Zealand, these loads are above acceptable and require load reduction. Loads are impacted by natural processes and land management practices.

    The dataset - what is it?

    A detailed document provides the current state of 4 contaminants - nitrogen (N), phosphorus (P), Escherichia coli (E. coli) and sediment in New Zealand water bodies. The receiving water bodies are lakes, rivers and estuaries. For each of the four contaminants compliance, local excess loads, regional and national load reduction and critical catchments are covered.

    Why it's important

    Ecosystem health and water quality are paramount to support all water uses. The purpose of this document is to assist Regional Councils to set catchment practices. Regional Councils may adjust allowable land use activities impacting Māori landowners.

        Caveats

        The study has used all the available data. Therefore, it would be difficult in most catchments to improve on the analysis. However, because the models were all national in extent, there may be a degree of model bias when the results are applied at fine scales.
