The entire west coast of the North Island from Wanganui to Cape Reinga to 12 miles from shore is under either a prospecting or exploration permit for mineral mining.

KASM (Kiwis Against Seabed Mining) are holding a presentation about seabed mining on September 5 2012 at the Muriwai Fire Station, Cnr Motutara & Coast Rd, Muriwai. All welcome.
