This follows on from the historic approval of the Golf Ireland proposal by golf clubs recently where 94% of the GUI ballot and 100% of the ILGU vote signalled a new beginning for the sport across Ireland.
The board, which is charged with getting Golf Ireland up and running ahead of the official launch of the body in 2021, includes four representatives from both the ILGU and GUI with O'Connor as an independent chairman.
Speaking about his role, O'Connor said: "I see the establishment of Golf Ireland as a historic new beginning for the sport in Ireland, building on the great work over generations by the GUI and the ILGU."
