Higher fruit prices have helped push up the overall cost of food.
In the year to July, rising prices for grapes and avocados sent fruit prices jumping skywards by 7.9 percent, and overall food prices by just over 1 percent.
Restaurant meals and ready-to-eat food also rose by almost 2 percent, while soft drinks jumped by 3.9 percent.
Official figures show food prices rose by 0.6 percent last month, after a similar increase in June.
Last month, mandarin and grape prices rose further, as did those for meat, poultry and chicken.
A drought in the US has pushed world beef prices to record highs, bringing New Zealand's beef prices up by 7.1 percent.
However, the prices of bread and butter fell.
