The decision to sack Piveni Piukala was made by Cabinet last Friday, reports Kaniva Tonga News.
A government statement said the grounds for termination included incompetence, acting in bad faith, and failure to follow due process in appointing the chief executive of the Tonga Broadcasting Commission, or TBC.
On Wednesday, the TBC reported the termination followed Mr Piukala's decision to decline a request from the prime minister to suspend three TBC staff members and to investigate them for alleged misconduct.
