Stats NZ says food inflation was back up five-percent for the year to July.

The heftiest increases include butter rising 42-percent, cheese 29, and produce climbing more than seven.

Infometrics Principal Economist Brad Olsen says other essentials like milk, steak, and mince are also going up.

Olsen says food price inflation probably won't impact next week's Reserve Bank announcement, but it is uncomfortable for households.
