Coastal activities occur in the Coastal Marine Area (CMA), which extends from a mark on the shoreline known as mean high water springs out to 12 nautical miles. The CMA can also include rivers where they enter the sea, up to a point which is defined in the Resource Management Act. There are a wide variety of activities including construction and use of structures (including boatsheds), swing moorings, movement and extraction of material, driving on beaches,  dredging, discharge of contaminants, and occupation of space.  

Our compliance team monitor coastal resource consents. High risk activities are monitored at least once a year, whilst some low risk activities are not monitored.  

All applicants for coastal activities must check whether there are any Customary Marine Title applicants under the Marine and Coastal Area (Takutai Moana) Act 2011 (MACA) for the area that their activity will take place. More information on the MACA can be found on this website.
