The document outlines the aims and approach of Healthy Families New Zealand, an initiative to improve population health. The initiative seeks to (1) prevent chronic disease by promoting healthy choices, physical activity, and healthy weights; (2) encourage communities to live healthier lives; and (3) reach about a quarter of New Zealand's population. It will establish a workforce of about 75 staff and invest $10 million annually, mostly in staffing. Ten locations across New Zealand will implement the initiative through community leadership and multi-sector engagement to drive sustainable healthy changes.
