Currently Greater Wellington monitor intertidal estuary sediment quality annually to understand the natural variation within the environment and the impacts of human activities. Other studies such as subtidal sediment and macrofaunal assessments, habitat mapping, and bathymetry surveys are undertaken every four years or when substantial shifts are recorded during sediment plate surveys. Current and historical data up to the end of June 2022 are presented on maps and tables within this web report to provide an indication of the health of the Harbour over time. An interactive version of this report can be accessed from the water monitoring page.
