Communities are voicing concerns over high strength beers being a 'court case in a can'. 

The products are being sold as singles in supermarkets and liquor stores and are stronger than RTDs, ranging from 7% to 16%. 

Communities Against Alcohol Harm have been raising the issue of the beers at a number of public hearings in Auckland. 

Secretary Grant Hewison says the beers present a much bigger issue compared to some other products. 

He says they're designed to be consumed quickly, are in 500 millilitre single cans, are cheap and are easy for someone vulnerable to stow in a pocket or bag.
