Gardai and Revenue Officers seized over 38,000 cigarettes in Enniscorthy last week with an estimated street value of €26,000.
The seizure took place on Wednesday following a joint intelligence led operation.
A search warrant was executed at a residential property in the town on Wednesday afternoon.
A spokesperson for the gardai in Enniscorthy said the cigarettes, which were branded 'Marlboro Gold', 'NZ Gold' and 'Sobranie', represented a potential loss to the exchequer of €20,500.
No-one was arrested in relation to the seizure, however, investigations into the matter are ongoing and the find was part of ongoing multi-agency operations targeting the supply and sale of illegal tobacco products in the shadow economy.
