Domino's Pizza said that sales in Ireland rose by 3.7% to €11.5m in the 13 weeks to the end of September.
The company, which has 48 outlets in Ireland, said that like-for-like sales have now seen nine periods of consecutive positive growth. They rose by 2.4% in the latest quarter, despite the unusually warm weather.
The group, which has stores in Ireland, the UK, Germany and Switzerland, said that total sales for the third quarter grew by 10.4% to £140.9m. Year to date sales up by 11.1% to £437.9m, it added.
Online sales also continue to grow strongly, with digital sales now accounting for 62.4% of UK delivered sales compared to 58.4% the same time last year.
"I am pleased to report another quarter of solid like-for-like sales growth across all four of our markets. The introduction of our new store design meant a delay in first half store openings, but the programme is now well underway," commented the company's chief executive Lance Batchelor.
"We are making good progress in transferring our German corporate stores across to franchisees, which will be a significant step forward in the evolution of this new growth market," he added.
The company's chief executive said it is confident of meeting City expectations for the full year.
