People are being asked to give their views on how to improve food labelling.
A committee overseeing a review of food labels in Australia and New Zealand is about to start public consultations.
Meetings are scheduled for Christchurch and Wellington in March.
Green Party food spokesperson, Sue Kedgley, says the Green Party in both New Zealand and Australia supports a traffic light labelling system.
She says independent nutritionists would determine which foods get a green label for being healthy, orange if they are marginal and red if they are unhealthy.
Ms Kedgley says that would allow consumers to see what type of food it was at a glance.
However the Food and Grocery Council says the proposed traffic light system is overly simplistic.
It says it supports percentage daily intake labelling that some products already have.
