Best-before labels are only a guide that quality may be affected.
New Zealand food and consumer experts say the idea is a good one.
NZ Guild of Food Writers president Trudi Nelson said best-before and use-by labels were discussed at the guild's meeting in November, at which sustainability was the theme.
She said many people tended to throw food away when it passed the best-before date. But most of those products were still edible.
"Reducing food waste is all about sustainability for us. New Zealanders are a savvy bunch of food lovers. We read labels, shop at farmers' markets, buy seasonal and organic where we can.
"So let's think outside the supermarket bag - eat cheese that's a few weeks out of date, cook with a can of tomatoes that's passed its best-before date ... "
Mrs Nelson said statistics revealed at the three-day annual conference showed that $470 worth of food was being thrown away per person, each year.
A total of 15 per cent of grocery items bought by Kiwi households ended up in the bin.
"We promote ourselves as being green and clean, so let's lead the way in reducing food waste," Mrs Nelson said.
Consumer NZ chief executive Sue Chetwin also welcomed the proposal to remove best-before dates - saying many people continued to confuse that with use-by labels.
"Use-by labels, you absolutely have to have.
"But the best-before date is really about the quality of the food."
Ms Chetwin said many non-perishable foods could be eaten months, even years, after the best-before date.
It was up to consumers to decide whether they felt a particular food was still good enough to eat, she said.
