Solomons Islands has a new Minister of Mines, Energy and Rural Electrification, as David Pacha swaps places with Samson Maneke.
Mr Maneke will now be the Minister of National Unity, Peace and Reconciliation.
They will both be sworn in today.
The Prime Minister, Manasseh Sogavare, says the reshuffle is necessary considering the ministers' expertise.
The Ministry of Mines has come under constant and heavy criticism for the way it has handled bauxite mining operations on Rennell Island in Renbel Province.
Mr Pacha has been Minister of Mines before, under former Prime Minister Derek Sikua.
