Northern Ireland's largest supermarket Tesco's market share is up by 1.4%, latest figures show.
It follows a small drop in the chain's market share last month.
At 34.8%, more than a third of food, drinks, alcohol, household, health and beauty products bought here were purchased at one of the chain's 50 stores - according to Kantar Worldpanel.
The figures are based on the 52 weeks to November 6, 2016.
Meanwhile, the region's second largest retailer, Sainsbury's, saw a 0.2% drop in its market share to 17.4%, comparing to Asda's 17.3%.
Sainsbury's operates 13 stores here compared to 17 Asda stores.
But the biggest winner was Lidl which saw the largest increase - with an extra 1.9% of the total more spent here compared to last year, bringing its market share to 5.1%.
The German retail chain has 38 stores across the region and has continued to push its range of Northern Ireland produce.
Other multiples, a category including Dunnes, M&S, Co-op and Iceland, also saw a 1.9% uplift in market share to 9.2%.
