New Zealand's largest Māori public health organisation is backing new research from the University of Otago to take bold action against the obesity crisis.
The research says two-thirds of food sold at rugby and netball games is considered unhealthy, undermining the positive impact of physical activity.
The research shows that sugary beverages, chocolate, potato crisps and fried food are the most commonly available at sporting venues.
Hāpai te Hauora chief executive officer, Lance Norman, said they've worked with community groups for a number of years on this kaupapa or issue.
Last year Hāpai partnered with Aotearoa Maori netball to go 'fizz free' to encourage no fizzy drinks which is now standard for their future tournaments across the country.
"Our focus has always been on community-led initiatives because in our experience these provide the greatest engagement, and the most sustainable change.
"There's no point just riding in and telling communities they're doing things wrong and then putting the burden of change on them alone. There has to be financial and educational support behind these policies," Mr Norman said.
They're calling on minister for sport and recreation Grant Robertson and the minster of health Dr David Clark to help sports clubs to implement healthier nutrition policies.
