The head of the Criminal Assets Bureau has said 2018 looks set to be the busiest in its 22-year history.
CAB has now identified 973 targets across the country, up 60% from the 600 cases it had in 2016.
Detective Chief Superintendent Pat Clavin has said "the great majority of cases" involve drug trafficking, followed by those who are involved in burglaries and robberies.
"Certainly outside of Dublin we find that people are very concerned about the burglary and robbery gangs and we have done quite a number of operations where we suspect people have assets that are derived from robbery and burglaries".
The Criminal Assets Bureau was set up in the wake of the murder of journalist Veronica Guerin in 1996.
It is tasked with targeting assets obtained directly, or indirectly, from criminal conduct.
The agency has the power to seize assets if officers believe they are the proceeds of crime.
CAB said almost half of the targets it now has are based in Dublin with 177 suspects coming from west Dublin alone.
Limerick has the highest number of CAB targets outside of the capital, with the assets of 72 suspected criminals under scrutiny.
It is followed by counties Meath, Wexford, Kildare, and Louth.
CAB now has 350 asset profilers operating around the country. They have been trained to spot the trappings of unexplained wealth in their areas and feed back the information to CAB's headquarters in Dublin.
At local level, the agency has become much more active in targeting individuals who exhibit a flashy lifestyle, linked to the proceeds of drug dealing or other crimes.
Detective Chief Supt Clavin said its crackdown will continue in 2019.
"Our targets would be the biggest level of national figures who are involved in criminal feuding around Dublin, we have international cases but we also have local cases" he said.
"We don't just go after big cases we also go after smaller local cases and the reason we do this is try stop them from becoming bigger criminals, to catch them earlier".
CAB is asking the public for more tip-offs about people who may be living suspiciously lavish lifestyles, without any visible means of support.
"They might see somebody who changes their car every year, who takes a number of expensive holidays to places like Las Vegas, to the States, to Dubai and always appears to have spending that is not in keeping with their earnings", he said.
