UK supermarket giant Tesco is promising to end edible food waste and there are calls to do the same in New Zealand.
More than 100,000 tonnes of food is thrown away by local industry every year.
But there's a growing number of people trying to save it.
One such company is KiwiHarvest, a food rescue company that saves high-quality food from being wasted and delivers it to those most in need.
Maria Madill, Auckland manager of KiwiHarvest, told Newshub: "No food business wants to see good food going to waste.
"They all want to be doing something good for their community and we are the enablers."
The company started in 2015 and now delivers more than 40,000kg of food every month.
Children at Tamariki Ataahua early learning centre get up to three meals a day and owner Sharon Stephens says donations help keep the pressure off families.
KiwiHarvest driver Terry Marsters says that doing his bit to help people is its own reward.
Many companies donate to KiwiHarvest, including Countdown Supermarkets which has committed to zero food waste going to landfill by 2020.
