Why is food so expensive?

Food prices were 7.6 per cent higher than in March last year, the highest annual rise in food prices in ten-years. The last time food prices rose so much in a year was July 2011 - that rise was 7.9 per cent but was influenced by the rise in GST the previous year. Stats NZ recorded increases in every food price category it measures - the most dramatic - an 18 per cent increase in the price of fruit and vegetables.
