A human rights advocacy group in the Cook Islands says a shared database should be set up with the government to target abusive employers.
Punanga Tauturu works with victims of domestic abuse and says it has come across cases of foreign workers who have been forced to surrender their passports or work 14 hour days.
Its spokesperson, Nga Teinangaro, says it refers cases to the labour and employment relations office but sharing information across organisations would help pinpoint and monitor employers that take advantage of their workers.
"Some of the work they do is not in line with the contract that they have put in place, where they actually work more hours than is stated in the contract and they also do other jobs apart from what is stated on the contract. Our main awareness is for for people out there in the community, foreigners working here, to know where to go to."
Nga Teinangaro, says a public list of abusive employers would also help foreign workers find reputable jobs.
