Last month, Mr Pohiva labelled the state broadcaster an enemy of government, saying he was not happy with its operations and someone else might better serve its role.
Tapu Panuve has now resigned as TBC chair, thanking the government for the opportunity, but adding that if a stakeholder is not happy, it is time to leave.
Mr Pohiva says he forced Mr Panuve to resign and he is working to replace the general manager Nanise Fifita as well.
Local media report sports administrator 'Ahongalu Fusimalohi has been appointed the new chair.
