About this report

This report was commissioned by the Technical Leaders Group for the Healthy Rivers Wai Ora Project Report No. HR/TLG/2016-2017/4.3

The primary objective of this report is to provide evidence around the state of water quality in the Waikato and Waipa River catchments in 1863. Three secondary objectives are used to focus
this research:

  1. Estimate the state of water quality in the Waikato and Waipa River catchments in 1863
    using predictive modelling.
  2. Discuss the findings with respect to historical records and previous research.
  3. Indicate the effect that future policy actions—derived from the HRWO process—are
    likely to have on surface water quality.
