With sales growth of 3.1% in the 12 weeks to 22 April, SuperValu is once again the grocery retailer with the largest share (22.3%) in the Irish market.
According to Kantar Worldpanel, SuperValu’s growth recently has been especially pronounced in the Dublin region, with sales in the retailer’s Munster heartland remaining steady.
This is the first time SuperValu has held top spot alone since July of last year.
Tesco has also seen strong growth in the past year, with the UK-owned company in second spot with a 22.2% market share.
Tesco has continued to build on its strong start to 2018, Kantar’s assessment states, with overall sales up by 6.1%, almost twice that of the market as a whole.
Although Tesco’s performance in Dublin is strong, the rest of Leinster contributed the most to growth, with the retailer’s share jumping from 26.1% to 28%.
In contrast, Dunnes’ share growth in Connaught and Ulster in the 12 weeks to 22 April was offset by a drop in the Dublin region, where share fell from 26.2% to 24.8%.
Overall Dunnes now holds a 21.9% share of the Irish grocery market.
Commenting on the figures, Douglas Faughnan, Consumer Insight Director at Kantar Worldpanel, said: "SuperValu has attracted more shoppers through its doors and persuaded its customers to buy more items per trip.
"In addition, while performance remains strong in its Munster heartland, SuperValu’s growth in the capital is particularly noteworthy. The retailer’s sales in Dublin grew 4.5% compared to last year, second only to Tesco which saw growth of 7.4% in the city."
Meanwhie, Lidl and Aldi were the second- and third-fastest growing retailers this period, with sales up 4.2% and 3% respectively.
Kantar says Lidl’s growth was predominantly driven by its sales in Leinster (excluding Dublin), whereas Aldi experienced a strong 12 weeks in Munster, Connaught, and Ulster.
Frozen food sales proved a lucrative source of revenue for the traditional retailers, according to the report, with sales of frozen food at Tesco, SuperValu, and Dunnes outpacing those of fresh, chilled and ambient food and drink.
Overall frozen sales rose 7.3%, in line with Iceland’s continued expansion in Ireland.
The British retailer has attained a 6.3% share of frozen sales, driven by increased footfall through further store openings.
