New Zealand has the third highest obesity rate in the Organisation for Economic Co-operation and Development.
“Manufacturers themselves are beginning to bring in low-sugar options. We are starting to see a shift in the New Zealand market place,” added Chepuli.
“A bottle may be 600mls, which may include two to three servings, so if you’re going to drink that entire bottle you need to multiply those numbers up accordingly.”
