Outgoing Telecom chief executive Paul Reynolds was a competent leader who steered the company through difficult years, commentators say.
The company announced yesterday that Reynolds would leave before July next year.
The 54-year-old Scotsman joined Telecom as chief executive in September 2007.
Since then he has been forced to deal with a heavy bout of government regulation and a slump in the company's share price.
"He's had the most extraordinary period to lead the company through and all this stuff's been imposed on him by successive governments which he has been battling against. My feeling is that he has done well in an incredibly difficult environment," said Forsyth Barr analyst Guy Hallwright.
