Researchers say warning labels on booze bottles are woefully inadequate.

The research was conducted by fourth-year medical students at Otago University.

They found most alcohol containers have either no warnings, or a pea-sized pregnancy warning.

Researcher Tessa Grey says, instead, marketing material dominates alcohol containers.

She says little attention is paid to consumers’ right to know the health risks.

She's calling for mandatory standardised labelling which outlines alcohol-related risks.
