There was a slight increase in the inflation rate last month but it is still in negative territory, according to one measure.
Lower fuel costs continue to be the main factor in keeping down inflation.
The annual rate of inflation as measured by the Consumer Prices Index for March increased slightly, and now stands at -0.6 per cent, up from -0.7 per cent in February.
The annual rate as measured by the Retail Prices Index has also shown a small increase, and now stands at 3.4 per cent, up from 3.3 per cent.
Excluding housing costs, the annual rate of inflation shown by the RPI increased to 4 per cent in March, up from 3.9 per cent the previous month.
