The United Nations special rapporteur on indigenous human rights, Rodolfo Stavenhagen (right), visited New Zealand in 2005. He came to assess whether the Foreshore and Seabed Act 2004 breached Māori human rights, and concluded that it did. Stavenhagen is shown here with Ngāi Tahu chief executive Tahu Potiki at Tuahiwi marae, near Christchurch. The visit was prompted by complaints from Māori leaders about the act. Professor Stavenhagen's wide-ranging report commented on education, the environment and social services, and recommended constitutional reform based on the Treaty of Waitangi.
