The New Zealand foreshore and seabed controversy is a debate in the politics of New Zealand. It concerns the ownership of the country's foreshore and seabed, with many Māori groups claiming that Māori have a rightful claim to title. These claims are based around historical possession and the Treaty of Waitangi. On 18 November 2004, the New Zealand Parliament passed a law which deems the title to be held by the Crown. This law, the Foreshore and Seabed Act 2004, was enacted on 24 November 2004. Some sections of the Act came into force on 17 January 2005. It was repealed and replaced by the Marine and Coastal Area (Takutai Moana) Act 2011.
