SYDNEY (Reuters) - Australian broadcaster Nine Entertainment Co Holdings Ltd ( NNMTF ) said its chairman Peter Costello resigned on Saturday and has been replaced by non executive deputy chair Catherine West.

"Catherine West has been appointed Chair of NEC," the company said in a June 9 statement.

"The board wishes to thank Mr Costello for his contribution to Nine over more than a decade including eight years as chairman."

In addition to resigning as chairman, Costello would "also step down from the board effective immediately", Nine said.

Costello, Australia's former treasurer, said in a separate statement issued by Nine that the board needed a new chair to "unite them around a fresh vision".

West was appointed to Nine's board in May 2016 and became deputy chair in September 2023, according to Nine's corporate website.
