More than 150 estuaries around New Zealand are monitored regularly to check their health.
Estuaries are usually monitored for sedimentation, high nutrients, chemical contamination and habitat loss. Microbiological contamination is also monitored in many places to find out if the estuary is safe for swimming, other recreational activities and for gathering fish and shellfish.
See LAWA Land Air Water Aotearoa for freshwater and coastal water quality data from around New Zealand.
You can also get involved with a range of projects at the places of interest to you.
