The Retailers Association has urged a parliamentary committee not to proceed with amendments to liquor laws until the Law Commission has finished its review on the issue.
The Justice Select Committee is considering the Sale and Supply of Liquor and Liquor Enforcement Bill.
The bill was a response by the previous Labour-led government to a spate of alcohol-related attacks on shop owners in South Auckland.
If passed, the bill would make it an offence for an adult to supply liquor to a young person without parental consent and give councils a greater say in the number of alcohol outlets in their district.
But Retailers Association's chief executive John Albertson says the bill is failing to address key issues, including the supply of alcohol to minors.
