Concern over the disproportionate number of Maori people in prison is reflected within the psychiatric institution population as well where Maori and other cultural minorities are over- represented. Since 1990 and the New Zealand Department of Health's acceptance of the validity of the Treaty of Waitangi as a basis on which to negotiate change, a concerted effort has been made to redress health care inequities. Maori people, however, continue to press toward self-determination in areas that affect them most, including health care. With the introduction of the Health and Disability Services Act of 1992, self-determination may be a realistic goal since the New Zealand Government has promised to encourage greater participation of Maori people at all levels, to allocate resources that reflect Maori health needs and perspectives, and to develop culturally appropriate practices and procedures as an integral part of the health service system. 28 references and 3 tables
