Food prices in January were 0.8 per cent higher than a year earlier, driven by higher meat, grocery and take-away costs.
Higher costs for restaurant meals and ready-to-eat food made the biggest contribution to the increase in Stats NZ's food price index.
Ready-to-eat food prices rose 3.3 per cent in January compared to January 2018. Meanwhile milk, cheese and eggs were 2.9 per cent higher, while restaurant meals cost 2.3 per cent more. Meat, poultry and fish prices were 1.9 per cent higher.
Those increases were partially offset by a 5.8 per cent drop in fruit prices, with fruit and vegetable prices overall down 3.7 per cent. Non-alcoholic drink prices fell 0.9 per cent.
The food price index accounts for about 19 per cent of the consumers price index, which is the Reserve Bank's mandated inflation target when setting interest rates.
