Choosing Wisely is an international health quality improvement campaign designed to prevent harm by reducing the number of unnecessary tests, treatments and procedures, and by promoting shared decision-making. In this study, 8 Māori consumers and 7 Māori health practitioners were interviewed about the Choosing Wisely New Zealand campaign and its messages. Study participants highlighted issues ranging from lack of Māori participation in programme governance through to practical issues like meaningful and literacyappropriate health messaging, traversing consumer, practitioner, organisational and health-system aspects. Participant feedback also indicated the need for patients to have trust in the practitioner, a sense of autonomy and availability of advocacy and support in the consultation. The study authors noted that Choosing Wisely New Zealand is the first of the international programmes to acknowledge the possibility that their initiative might increase inequity for indigenous populations. They stressed the need to consult Māori early and to infuse Treaty principles and Māori knowledge and custom at every stage of the programme.
