A renewed call to restrict alcohol advertising and sponsorship, as young women under the age of 24 are drinking huge amounts of RTDs.

A Massey University study has found women who get RTDs from liquor stores drink around 24 litres a year - that's more than the heaviest group of male drinkers.

Alcohol Healthwatch executive director Dr Nicki Jackson told Larry Williams young people are exposed to high amounts of targeted alcohol brand advertising.

"Some of the restrictions that we need to be looking at is around advertising and marketing. These are young girls drinking heavy quantities of RTDs, they're very much marketed towards young people."

Dr Jackson said this is not what she wants for young girls.

"They're putting their brains at risk, they're putting themselves at risk of alcohol-related harm, there's aspects around getting pregnant and foetal alcohol spectrum disorder."
