Programme overview

Greater Wellington Regional Council’s river water quality and ecology monitoring programme provides information on the stream condition across the Wellington Region. Water quality and ecosystem health are currently monitored at 42 hard-bottomed and 9 soft-bottomed river and stream sites within each main river catchment (Whaitua). These sites were chosen to represent the major land uses and human activities and the natural diversity of rivers and streams in the wider Wellington Region. This report contains monitoring results from 2016/17 to 2020/21.
