So far this year, four officers have been convicted of the offence in Northern Ireland compared to eight at the same point last year.
In 2006, the PSNI's worst year for drink-driving, 22 officers were convicted of drink-driving.
A PSNI spokesman said of the latest figures: "The number of cases must be put into context of the overall size of the PSNI - just over 9,000."
"Of the four officers convicted, three were constables and one a reserve constable (part-time). Three were male and the other female."
The female officer had taken part in a road safety TV advertisement.
She subsequently had to edited out of the ad at a cost of £9,000 to the taxpayer.
Prior to the 2006, 2002 had been the worst year for drink-driving among police officers in Northern Ireland when 15 officers were found guilty of being over the limit.
