Grocery Supplier Cost Index

The Infometrics-Foodstuffs New Zealand Grocery Supplier Cost Index (GSCI), commissioned by Foodstuffs New Zealand, measures the change in the list cost of grocery goods charged by suppliers to the Foodstuffs North and South Island cooperatives.

List cost refers to the cost suppliers charge retailers before trade spend is applied; trade spend being any form of discount provided by a supplier to allow their goods to be discounted.

The Index utilises detailed Foodstuffs NZ data, across over 60,000 products, analysed by independent economics consultancy Infometrics to produce the GSCI and publish it on a monthly basis.
