Gardaí say that following a review earlier this year they are now satisfied with the integrity of the homicide statistics.
Deputy Garda Commissioner John Twomey has said minor misclassifications had been discovered, but that these cases need ongoing assessment because as evidence emerges classifications might change.
For example, an incident initially classified as assault might be changed to homicide.
The investigation began after it was suspected that some cases of murder, manslaughter and violent deaths may have been misclassified.
The move followed recent controversies over inaccuracies and exaggeration of garda road policing statistics.
However, at the Garda Representative Association conference last night, Mr Twomey said that following the review of 41 deaths, An Garda Síochána is satisfied that there had been a full and proper investigation into each one.
Mr Twomey also said that DNA samples had been taken from more than 1,000 convicted sex offenders following the introduction of legislation two years ago.
He said because these were historic cases and the offenders had variously been sent to jail, moved homes or left the country, it was not possible to take DNA from every one of them but gardaí had so far targeted 84% of those available.
Meanwhile GRA General Secretary Pat Ennis has said it would be wrong to make any comment on the ongoing investigation into falsified breath tests.
Speaking on RTÉ's Morning Ireland, Mr Ennis described it as a "systems failure" and said it was clear to the GRA that the blame for the debacle lay with the organisation and senior management, not individual members of gardaí.
He said he accepted there was an issue that needed to be addressed and it was imperative the public had faith in gardaí.
He said he knew there would be a dent in the confidence the public had in gardaí, but he was sure that would recover.
Mr Ennis said he had full confidence in Garda Commissioner Nóirín O'Sullivan.
Call for gardaí to be allowed have beards
A motion has been passed at the GRA conference calling for a change to the regulation that prevents gardaí from having beards.
Earlier this week, former GRA president Dermot O'Brien told RTÉ's Drivetime that "a well groomed beard is an entitlement to a man if they want to grow a beard."
He added that he could not "see any reason" why the existing regulation could not be changed.
However, while the motion was passed Ms O'Sullivan said there are other more important priorities for the force.
The association has rejected a separate proposal to link speeding fines to motorists' salaries.
The Road Safety Authority has said fining people on the basis of their income is being considered but had yet to be developed.
The GRA said it was vehemently opposed to the suggestion, with Mr Ennis saying it is extremely unhealthy in a democracy to incentivise the prosecution of people in any context.
