Four properties in the Carrickfergus, Ballycarry and Larne areas have been searched today.
Officers from the Paramilitary Crime Task Force executed a series of search warrants on the properties.
Following the searches documents, computers, and mobile phones were seized and will now be examined. At one property in Ballycarry around £6,000 cash was also seized. There were no arrests.
The searches related to civil recovery investigations and were undertaken with a view to identifying recoverable or associated property.
NCA branch commander Billy Beattie said they are determined to prevent those engaged in criminality from benefiting financially from their actions.
“Those involved in criminal acts should know that we are not just after them, but also their money.
“In respect of the searches carried out today, our investigations will continue with the material that we have seized,” he said.
And the PSNI’s Head of Criminal Investigation Branch, Detective Chief Superintendent Tim Mairs said the actions demonstrate the strength of the three agencies working together as part of the Paramilitary Crime Task Force, and their commitment to tackling the abuse of these vibrant communities by the criminal individuals and groups.
“We would encourage anyone with information to contact the police on 101 or alternatively information can also be provided to the independent charity Crimestoppers on 0800 555 111,” he added.
