Billionaire Gina Rinehart has quit the board of the Ten Network to focus on the construction of her giant iron ore project.
Also one of Ten's major shareholders, Rinehart failed to attend any of the broadcaster's board meetings in the 2013/14 financial year because of her commitments as chairwoman of Hancock Prospecting.
Construction of that company's US$10 billion ($12.8 billion) Roy Hill project in Western Australia recently passed the halfway mark, with the first shipment of iron ore scheduled for September 2015.
In the past 12 months Rinehart has secured crucial funding for the project, despite falling prices for iron ore amid rising supply.
John Klepec, the chief development officer at Hancock Prospecting, has attended Ten's board meetings on Rinehart's behalf since October 2013, and will permanently now replace her as a director.
