Health promotion in New Zealand has become an established approach in addressing public problems since the 1980s, through increasing use of intersectoral action, the use of public policy and mass media as promotional strategies, and the increasing control Maori have taken over the provision and purchase of health promotion services. An example of health promotional initiatives is the action put in place to reduce childhood obesity in primary schools. Research was completed to identify the barriers to improving school food environments and promoting healthy nutrition in primary schools in New Zealand.
