More than three billion dollars' worth of household food gets thrown in the bin every year. 

The Prime Minister's Chief Science Advisor, Dame Juliet Gerrard, has issued the government 27 recommendations, including a reduction target. 

Executive Director of NZ Food Waste Champions Kaitlin Dawson told Mike Hosking that we need to focus on other ways to lower the figures. 

She says there's waste in retail, farming, and manufacturing but overall, it's a system issue.
