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