The head of the Criminal Assets Bureau (CAB) Pat Clavin is one of three new assistant Garda commissioners selected by the Policing Authority.
The list also includes the first police officer from the PSNI, Paula Hilman, to be appointed to that rank in the Garda force.
The third officer on the list is Anne-Marie Cagney.
The three were chosen by the Policing Authority following a rigorous series of interviews and written examinations.
They were selected from a shortlist of seven who made it through to the final round of the competition.
Their names have now been submitted to the Garda authorities for clearance before the details of the appointments are publicly announced.
Det Chief Supt Clavin has been in charge of the CAB at a time of expansion and successful operations that led to a record haul of assets, worth in excess of €50m, being seized last year.
