Consumer concern around the rising number of products with caffeine on the market has prompted a review into New Zealand and Australia's policies governing food standards.
Those living in New Zealand and across the ditch have been asked to weigh up three options on guidelines which determine the sale of caffeinated products in both countries.
A subcomittee of the Australia and New Zealand Food Regulation Ministerial Council, which is responsible for the regulation of food and beverages in each country, is leading the review.
The policy options paper, which was finalised last month, highlights changes in the caffeine market over the past 10 years.
"The most significant changes have been seen in increases in sales of energy drinks and coffee-consuming culture outside the home,'' the report said.
