Morrow will remain with the telco until the end of March, when he takes over the reins at NBN Co.
No. 3 telco Vodafone has had a bumpy ride in recent years, but Murrow has managed to turnaround the telco once branded Vodafail by disgruntled customers, who fled the carrier, en masse.
Spanish - born Inaki Berroeta has served as President and CEO of Voda Romania since 2010 overseeing 3500-employees.
Under his leadership, the telco delivered growth and improved profitability in a competitive market, and led successful bid acquiring a 15 year spectrum license and rolled out the first 4G LTE services.
Morrow said Mr Berroeta's international experience and passion for the Vodafone family would ensure continued transformation of the company.
"Inaki is a great fit for the local team and his diverse background places him well to take Vodafone through to the next phase of its 3 year turnaround."
A 20-year veteran of the telco industry, he served as CEO of Vodafone Malta in 2007 and prior to this held various roles at Vodafone Spain, Global Star USA, AirTouch International Inc (USA), Airtel Moviles (Spain) and Keon (Spain and USA).
He holds a Masters of Science in Telecommunications from Bilbao Superior School of Telecommunications Engineering.
