The annual rate of inflation fell back to 4.9% in June from 5% in May, according to the Central Statistics Office.
Prices rose by 0.2% compared with May, but this was a smaller fall than in the earlier months of the year. The inflation rate is still well above the euro zone average, however.
Clothing and footwear prices fell by 1.7% in the month, but higher air fares and petrol prices pushed transport prices up 0.8%. Restaurant and hotels prices were also higher, while higher mortgage repayments continued to raise prices in the housing category. Mortgage interest costs have risen by 46% over the past 12 months.
The figures also show that Ireland's inflation rate, as measured by EU's harmonised index, crept up to 2.8% in June from 2.7%. This measure excludes mortgage interest repayments. Ireland has the second highest rate in the euro zone, well above the average of 1.9%.
Separate CSO figures show that industrial production in May dropped by 6.15 compared with the same month last year, though it rose 0.5% compared with April.
The seasonally adjusted figures also show that, in the three months from March to May, production also fell by 6% compared with the previous three months.
The biggest drop was in the modern sector - which includes technology and chemicals - where production in May was down 9.3% on the same month last year. In contrast, the traditional sector saw a rise of 4.1%.
