Thirty one suspected trafficked women sought help last year, according to the Immigrant Council of Ireland.
Potential victims were from Europe, Africa, Asia and South America.
Catherine Cosgrave, legal services manager with the Immigrant Council, said: “Of the 31 women who sought the protection and support of our frontline services and independent law centre, 11 were new cases – making the year the second busiest since we started work in this area a decade ago.
“Clients need assistance in terms of being officially recognised as a victim of trafficking, immigration and visa issues, asylum applications as well as access to supports to restart their shattered lives.
“Above all we must ensure that women and girls removed from the clutches of criminal gangs are not themselves treated as criminals.
