The Government rejects accusations it has gone soft on the regulation of drinks known as alco-pops, as a result of industry pressure.
National Party MPs came under fire as Parliament made its way through one of the last stages of the liquor reform legislation.
Justice Minister Judith Collins made several adjustments to the legislation in August, one of which backed away from regulating the sale and content of alco-pops.
Opposition MPs say those drinks are aimed directly at the youth market, and accused her of bowing to industry pressure.
The Government says the new law will still allow the regulation of alco-pops as needed, and that encourages the industry to act responsibly.
