Papua New Guinea's National Intelligence Organisation is appealing for more stringent checks on foreign workers entering PNG
The NIO says there are questions over the authenticity of entry claims of some foreigners who cite work contracts on major resource extraction projects.
The agency is concerned that workers for projects such as the Ramu Nickel construction in Madang may be entering without proper security, customs and immigration checks.
The Chinese company running the project, Ramu NiCo, denies the claims, saying it complies with PNG's laws.
However the NIO's Bob Nenta says a lot of foreigners enter PNG citing work contracts, but not all are genuine.
He says that a more concerted effort is needed by government agencies to check where these immigrants are headed.
"We are taking it to our highest level, that maybe we do need to do more work on this, tighten it up more, do more checks on whose coming and maybe to follow through to see where they are going, if they are going to Ramu and not anywhere else."
