The Infometrics-Foodstuffs New Zealand Grocery Supplier Cost Index showed an average 1.9% year-over-year increase in supplier costs for supermarkets in August, unchanged from July's result, according to an Infometrics report on Monday.
Supplier costs rose across all departments in August compared with a year earlier, with seafood and butchery costs remaining higher due to sustained global demand and pricing trends, although the pace of cost growth for chilled foods slowed a little amid slightly lower dairy costs.
"The August data continues a recent trend of a more elevated number of cost increases being recorded, but at a less intense pace than originally expected," said Brad Olsen, principal economist at Infometrics.
"Broader input cost data shows businesses were either less willing to raise costs, or unable to respond as quickly as the knock-on economic effects of the Middle East conflict emerged," Olsen added.
The renewed conflict continues to cloud the cost outlook for the remainder of this year, with oil prices moving higher again and raising expectations for further cost adjustments in the coming months, Olsen said.
