ASB Bank economist Kim Mundy said the food prices data was softer than expected, prompting it to pull down its forecast for second quarter inflation to 0.5 per cent, below the Reserve Bank's 0.6 per cent forecast.
ASB didn't change its view for interest rates and continues to expect the Reserve Bank to cut in August and November, she said.
Today's data show the decline in annual food prices was led by lower grocery prices which dropped 2.3 per cent.
Dairy product prices weakened, with cheese prices down 9.5 per cent, fresh milk slipping 3.9 per cent and yogurt falling 9.2 per cent. The average price of a kilo of cheddar cheese dropped to $7.68, from $9.12 a year earlier and marking the lowest level since September 2007, the statistics agency said.
Meat, poultry and fish prices dropped 0.9 per cent over the year as chicken fell 5.3 per cent, processed meat slid 2.9 per cent and lamb sank 5.2 per cent. Beef bucked the trend, advancing 4.3 per cent.
Fruit and vegetable prices increased 2 per cent over the year, with continued record high prices for avocados, up 146 per cent, partly offset by lower prices for tomatoes which fell 20 per cent.
Restaurant meals and ready-to-eat food advanced 1.6 percent over the year.
