Chief executive of Chorus Mark Ratcliffe has announced he will step down from the role around the middle of next year.
Ratcliffe was CEO of the company when it was a business unit within Telecom and led the demerger in 2011.
He has since then steered Chorus' role in the nationweide Ultra Fast Broadband initiative and fibre roll-out.
The announcement comes as Chorus this morning reported a net profit after tax of $91 million, unchanged from a year earlier, and earnings before interest, tax, depreciation and amortisation of $594 million for the year ended 30 June 2016.
The fibre roll-out is now 57 per cent completed. The company has recently said it has struggled to find qualified staff to cope with the roll-out as well as regular winter weather interferences to its copper network.
