This site is in the lower part of the Upper Waitematā Harbour near the narrow entrance to the Central Waitematā Harbour. The site has been monitored since 2005 to track any impacts of urban development in the catchment.
Mud content, contaminants and macrofauna are sampled roughly every five years. Mud content is very high, and some heavy metals are possibly impacting the ecology of the site resulting in poor overall health.
