Tāmaki Estuary
The Tāmaki Estuary is an important waterway that feeds into the Hauraki Gulf. It is located on the Tāmaki Makaurau isthmus. From its mouth between Karaka Bay and Musick Point, it extends approximately 17 km southward, with several tributaries on either side, all of which are themselves also estuarine in their lower reaches.
The Estuary and its tributaries have long been undervalued yet are important natural and community assets. For many years the Estuary has been detrimentally affected by under investment in pollution control, storm-water management and treatment, and ecological restoration. It suffered significant degradation, especially throughout the 20th century, from both industrial pollution from factories and fine silt and mud sedimentation from inadequately controlled soil runoff that emanated from commercial and residential development sites within its catchment area.
