New figures show that the German discounters Aldi and Lidl have again seen their share of the multi-billion euro Irish grocery market grow.
Kantar Worldpanel figures show that the rival chains now have a combined 13.8% share of the grocery market here, compared to an 11.8% share a year earlier.
The latest figures - for the 12 weeks to June 9 - show that Tesco's position as the country's biggest grocery retailer took another hit in the 12 weeks.
Its share of the market has fallen from 28.6% to 27.7% while Dunnes’ share now stands at 21.9%, down from 22.4% a year ago.
SuperValu and Superquinn have both performed in line with the market, maintaining their market shares of 19.7% and 5.5% respectively.
The Kantar Worldpanel figures also show that the rate at which grocery prices are increasing has begun to slow. Grocery prices increased at 4.8% in the latest period under review, the first time the rate has dipped under 5% in the past six months.
''Throughout 2013 the price of our groceries has been increasing at over 5%, higher than the rate of inflation and a trend which has put a huge strain on consumers’ wallets. Now we are seeing grocery prices increasing at the slower rate of 4.8%, a welcome sign for shoppers that months of rapid increases may be coming to an end,'' commented David Berry, commercial director at Kantar Worldpanel.
The overall performance of the grocery market dropped back slightly this period, with sales declining by 0.2% compared to marginal growth of 0.1% last month.
