In 2009 the National-led government, as part of a November 2008 confidence-and-supply agreement with the Māori Party, undertook a review of the Foreshore and Seabed Act 2004. In response to the review the Marine and Coastal Area (Takutai Moana) Act 2011 was passed, repealing the 2004 act. The new law replaced Crown ownership of the foreshore and seabed with a ‘no ownership’ regime, and provides for the recognition of the customary rights of iwi, hapū and whānau in the common marine and coastal area.
This has resulted in a massive number of claims for customary title to the foreshore and seabed. Contrary to assurances given by the government, the claims include not only remote areas of the coast, but every inch of the common marine and coastal area of New Zealand. Over 580 applications have been lodged for the recognition of customary rights and customary marine title over 10 million hectares of the foreshore and seabed out to 12 nautical miles (22 kilometres), including harbours, estuaries and river mouths, the airspace above and many of the minerals below.
