NBN COO Greg Adcock is due to leave the company after a two year stint and won't be replaced.
According to media reports, Adcock and CEO Bill Morrow came to a mutual decision not to continue with the COO position.
Adcock will move into an advisory role reporting to Morrow until his departure which will happen by early 2016.
Morrow said that he appreciated Adock’s contributions in helping the company overcome many of the challenges it was facing in network delivery.
For example, Adcock led the rebuilding of its delivery partner relationships, the stabilising and ramping up of the fibre-to-the-premises (FTTP) build program, the start of the fibre-to-the-node (FTTN) build and the launch of the company’s first satellite, Sky Muster in October this year.
“Greg leaves the network engineering and deployment team with strong leaders, ready to scale and accelerate the build of the NBN network,” he said.
In a statement, Adcock said he was pleased to have been a part of the leadership team driving the progress made over the last two years.
“I can’t thank the NBN team enough for their focus and dedication and I will watch their continued progress with pride.”
Meanwhile, NBN executive general manager, regional deployment, Peter Ryan will step into an interim chief network engineering officer role heading up the network engineering and deployment department.
A search will be undertaken for a permanent replacement, said NBN.
Prior to joining NBN, Adcock had been at Telstra for twenty years. His last role involved "delivering on Telstra’s infrastructure commitments" under the telco's deal with NBN.
