However, monthly food prices fell 0.2% in the month of September, following a fall in vegetable prices.
Prices for cucumber, lettuce and capsicum led the drop in vegetable prices in September, Mr Haigh said.
The prices for items found in salads typically began to fall in September months as warmer weather arrived, although the falls for September this year had not been as large as in previous years, he said.
Fruit prices fell 0.5%, influenced by lower prices for oranges, grapes and bananas, Mr Haigh said.
