National says the State has a role to play in obesity, but it's up to people to decide which choices they make.
Leader Judith Collins has copped criticism from some people for saying that obesity is a weakness and is a matter of personal responsibility.
Her health spokesman Dr Shane Reti told Kate Hawkesby whether obesity is a weakness is up to the individual.
He says the Government's role is to give people all the education they could possibly want, so they make the best choice.
Labour leader Jacinda Ardern says the comments by Judith Collins show the Opposition has nothing on one of the most significant health issues we have.
Shane Reti says people have a choice of one option over another, but whether it's a personal weakness is up to the individual.
