Irish grocery sales rose by 3.3% in the three months to the middle of July, while SuperValu retains the largest market share of any grocery retailer here at 22.5%.
Tesco is next, despite a drop in sales, with a 21.9% share, followed by Dunnes Stores on 21.3%.
Commenting on the recent growth in the sector, Director at Kantar Worldpanel David Berry said: "Ireland’s involvement in the Euro 2016 certainly looks to have had a positive impact for the major supermarkets.
"Alcohol sales over the past 12 weeks are 11% higher than the same time last year, as consumers stocked up more often and bought more each time they shopped.
"Soft drinks, confectionery, crisps and snacks all also saw positive sales growth as football fans made the most of the opportunity to treat themselves."
Meanwhile, Lidl has the largest market share of the discount retailers at 11.9%, while Aldi's share of the Irish grocery retail market is 11.2%.
In the past year an extra 38,000 households have visited Aldi, contributing to a 3.7% sales growth in the past 12 weeks – a clear improvement from March of this year when growth stood at just 0.8% and the discounter was losing shoppers.
The figures from Kantar Worldpanel in Ireland also show grocery market inflation stood at 2.6% for the 12-week period ending 17 July.
