Two of the Tonga Broadcasting Commission's most senior journalists were recently moved out of the newsroom into sales, and a popular talkback programme was cancelled.
The Tonga Broadcasting Commission and the government have had a strained relationship this year with Prime Minister 'Akilisi Pohiva calling the broadcaster 'an enemy of government.'
However, revenue losses and unpopular content were the reasons given for the changes.
Mr Fonua said the changes have had an impact on the amount of election coverage broadcast on the TBC.
