"We need to get it right and leave no loopholes for this industry, but we were already pushing this legislation quickly and it is now getting quicker.
"We are fully aware of the concerns of New Zealanders around these products and this industry."
Labour associate health spokesman Iain Lees-Galloway said while his party was happy with the intent of the Bill, it could have been introduced much sooner.
While the Bill would establish a licensing regime for people wanting to manufacture and import the substances, the Opposition wanted that widened to include the people who sold legal highs.
"We also want greater ability for communities to have their say about exactly where the shops that sell legal highs can be placed in their communities."
