Communications Minister Malcolm Turnbull has appointed the internet entrepreneur Simon Hackett to the board of the company in charge of the National Broadband Network rollout.

Mr Hackett founded the internet service providers Internode and Agile Communications.

Mr Turnbull has also appointed the former head of NBN Co's construction division, Patrick Flannagan, to board, as well as former Bigpond and Telstra executive Justin Milne.

In a statement, NBN Co executive chairman Ziggy Switkowski said the two appointees are well-established industry figures with lengthy careers in telecommunications and broadband.

"This is a period of transition for the company and it will be a great asset to have a new board that brings decades of combined experience in the industry," he said.

It comes after almost the entire NBN Co board quit in September.

Dr Switkowski was appointed as head of the government-owned business after the former chief executive Mike Quigley resigned in July.

The new appointees will be joined on the board by exisiting directions Alison Lansley and Kerry Schott.

The board is expected to deliver a review of the NBN rollout by the start of next month.
