HPA is a Crown entity established on 1 July 2012 under legislation to lead and support national health promotion initiatives. It has a board appointed by the Minister of Health, and staff in Auckland, Wellington and Christchurch.
In addition to national health promotion initiatives, HPA performs all functions previously undertaken by the Alcohol Advisory Council (ALAC) and the Health Sponsorship Council (HSC).
The Big Change Starts Small campaign focuses on the quality and quantity of food families are eating as well as inactivity and sedentary behaviour. The campaign call to action is for families to make small changes to improve their diet and to be more active.
