Introduction
The coastal marine area (CMA) applies to foreshore, seabed, water and air from mean high water springs (MHWS) to 12 nautical miles (territorial sea) (s. 2 RMA).
Determining Mean High Water Springs
The MHWS boundary has not been surveyed for Auckland, as it has a dynamic and varying location. The indicative coastline shown on the maps is an approximate representation of MHWS-10, which is the level equalled or exceeded by the largest 10 per cent of all high tides. Where the line crosses a river mouth and the CMA boundary has been defined by agreement between the council and Department of Conservation, the CMA boundary at river mouths is indicated on the maps and detailed in
Appendix 6.4.
As a jurisdictional boundary, the exact location of MHWS needs to be defined on a case-by-case basis. Where activities are close to the indicative coastline, a site-specific survey will be required to determine the location of MHWS and the actual CMA boundary. If a site-specific survey determines that MHWS is not located in the position shown on the maps, the zone of the adjacent land or CMA applies.
Management Framework
The CMA is managed through zone, precinct, overlay and bylaw provisions. The CMA zones are:
General Coastal Marine zone (CMA only)
This zone includes the majority of Auckland's CMA. It covers all of the CMA outside of the zones listed below.
Marina zone (land and CMA)
This zone provides for the development and operation of existing marinas. The Marina zone covers both land and CMA to enable integrated consideration of activities that cross MHWS.
Mooring zone (CMA only)
This zone contains objectives, policies and rules for moorings within a Mooring zone and has been established to provide for the mooring of vessels at strategic locations. By establishing mooring areas the Unitary Plan seeks to concentrate moorings in defined locations and avoid a proliferation of moorings throughout the CMA.
Minor Port zone (land and CMA)
This zone provides for the integrated and efficient operation of particular minor ports in the Auckland region. The Minor Port zone includes the Port of Onehunga, the Gabador Place Wharves, the Papakura LPG Terminal and the Chelsea Sugar Factory Wharf. The zone includes land as well as CMA at the Port of Onehunga and Gabador Place to integrate management across mean high water springs.
Ferry Terminal zone (CMA only)
This zone provides for the integrated and efficient operation and development of existing ferry terminal facilities, and provisions for the development of new ferry terminal facilities.
The Ferry Terminal zone applies to terminals at Devonport (includes Devonport and Victoria wharves), Stanley Bay, Northcote, Birkenhead, Beach Haven, Hobsonville, Mātiatia and Kennedy Point (Waiheke Island), and Whangaparāoa, Tryphena and Port Fitzroy (Great Barrier Island). The existing ferry terminal facilities at Gulf Harbour, Bayswater, West Harbour, Half Moon Bay and Pine Harbour are within marinas and are in the Marina zone.
Defence zone (CMA only)
This zone provides for the continued operation of defence activities in the CMA adjacent to the HMNZ Naval Base in Devonport and the Onetaunga Bay Wharf (Kauri Point).
City Centre zone and waterfront precincts (land and CMA)
This area is included in the City Centre zone to recognise the key role of the waterfront as part of the city centre. This area includes the Port, Viaduct and Central Wharves, Wynyard and Westhaven precincts.
Auckland Airport sub-precinct coastal (CMA only)
The CMA adjacent to the Auckland International Airport is included in the precincts section.
