National's Food Minister, Kate Wilkinson, will not say before the election whether she supports the "traffic light" food-labelling system recommended by an official transtasman review - a silence tagged "despicable" by the Greens.
Ms Wilkinson will not reveal her position on the controversial proposal and other food labelling recommendations until she has presented them to next month's meeting of the transtasman food ministers' council.
Labour doesn't have an opinion on the recommendations, but health spokesman Grant Robertson said there was value in traffic-light labelling.
Greens food spokeswoman Sue Kedgley welcomed the report's proposals to improve nutrition labels and its urged enhancement of Australia's country-of-origin labelling, a policy her party is striving to have applied here.
She abhorred consumers' being kept in the dark about the Government's position until after the election. "[It] is despicable, frankly."
