Nestle is removing its 4.5 health star rating from Milo powder after concern from Consumer New Zealand.
The consumer watch dog gave the product a Bad Taste Food Award in 2016, with chief executive Sue Chetwin saying it was 4.5 stars out of five for a product that was almost "50 per cent sugar".
The high health star rating was based on the drink being made with skim milk, however on its own the powder earned just 1.5 stars.
"It's the skim milk that boosts the number of stars," Chetwin said. "But our research found most milo drinkers prepare the drink with standard blue top or full-cream milk."
Chetwin said the product packaging also featured pictures of active young sportspeople. The 4.5 star health rating would be removed from packages in June.
