This study investigates the way in which Maori values are incorporated into environmental decision-making. Recently, the implementation of large resource developments have drawn protest from Maori communities and focussed attention on these values. The study examines the nature of these values, associated with the way the Maori people use and perceive the environment, and determines that these are still strongly held today. It then establishes that as an indigenous minority culture Maori values should be specifically considered. From this basis, environmental decision-making procedures are examined. The findings reveal that many procedures do not sufficiently account for Maori values. Two options are formulated to improve the existing situation. The first option looks at changes to present procedures. The second option investigates implementing reforms to encourage earlier participation with Maori communities.
