Childhood obesity is a critical issue in New Zealand that we can no longer afford to ignore. Currently, one in three children is overweight or obese, putting the health of an entire generation at risk if we continue to delay taking action. This issue highlights a significant matter of equity. Māori and Pacific children and those from socio-economically deprived backgrounds are disproportionately affected, reminding us of the systemic barriers rooted in historical factors that exist within our society. Efforts focussed on changing individual behaviour have achieved limited success in reducing childhood obesity rates. Therefore, it is necessary to shift our focus upstream and address the root causes of this issue. This viewpoint piece underscores the role of the obesogenic environment as the primary driver of childhood obesity, advocating for an upstream approach to enact broader changes in the food environment. Within this framework, this piece puts forward three policy measures that could be essential in addressing the childhood obesity epidemic: implementing a tax on sugary beverages, restricting unhealthy food marketing and ensuring access to healthy food in schools. These policies are backed by substantial evidence of their efficacy, cost-effectiveness and potential to improve health equity, including contextual evidence from successful international models. However, despite ample evidence and support, New Zealand has fallen behind international standards in adopting these measures, partly due to resistance from the food industry and the need for stronger political leadership. Thus, a “call to action” is needed to overcome these challenges, mobilise against the current policy inertia and make addressing childhood obesity a priority.
