Costcutter has insisted it is making “good progress” in resolving the delivery and availability problems still being experienced 10 weeks after it switched its distribution contract from Nisa to Palmer & Harvey.

Chief executive Darcy Willson-Rymer said availability rates were up and “they continue to rise across the network.”

The symbol group held its annual conference - attended by members, suppliers and P&H - this week in Portugal, where Willson-Rymer said the continuing problems had been discussed.

“We recognised the challenges of the migration and it was also an opportunity to look ahead to new developments and discuss future priorities for the next 12 to 18 months,” he said.

“This will ensure we continue to focus on our members, their customers and working closely with our suppliers.”

However, retailers are losing patience with the ongoing problems, with a small number considering striking in protest.

Comments have been left on, as well as the website of The Grocer’s sister publication Convenience Store, calling for strike action.
