A trip to the supermarket hit the wallet hard in January after food prices rose 2 per cent.
Statistics New Zealand said the rise in the price of food was the biggest monthly increase since June 2013 after five months of decreases in 2015.
The seasonally adjusted increase in price was 0.4 per cent, as fruit and vegetables were more expensive in the summer months.
The fresh produce aisle was where the price jump was most noticeable, with fruit and vegetables costing 4.4 per cent more in January. But, when seasonally adjusted, fruit and vegetable prices were down 0.7 per cent.
Fresh milk rose 4.9 per cent, chocolate increased 5 per cent and the price of plain biscuits went up 14 per cent.
