This site is in the middle basin of the Upper Waitematā Harbour, south of Herald Island. The site has been monitored since 2005 as part of an estuary-wide network to detect impacts of urban development in the surrounding catchments.
Mud content and macrofauna are sampled every three months, and contaminants every three years. Mud content is moderately high and has increased since monitoring began, whilst contaminant concentrations are low.
