Questions have been raised about the Tongan government's plans to spend $US1.9 million dollars setting up a new security office.
Our correspondent says the Tonga National Security of Information Office appears set to try and curb the leaking of key government information.
Kalafi Moala says it will work with Tonga police and government agencies in New Zealand and Australia, though there has been no explanation of what their role might be.
Don Wiseman asked Mr Moala what the government might be keen to keep hidden.
