In New Zealand (NZ), 88% of health loss is now caused by non-communicable diseases, in part attributed to low levels of physical activity (PA) and high levels of inactivity, and the downstream impacts of these, including suboptimal blood glucose profiles, body size, and blood pressure.1 While the NZ 2016 PA Report Card on Physical Activity for Children and Youth2 revealed relatively high levels of PA, approximately one-third of NZ children and youth did not meet PA recommendations of ≥60 minutes of moderate-to-vigorous physical activity (MVPA) per day. The purpose of this paper is to summarize the methods for grade calculation and results of the 2018 update of the PA Report Card for NZ.
