Joining Verbiest are investment banker Charles Sitch, NZ Post deputy chair Justine Smyth, Transpower director Maury Leyland and Hong Kong telecommunications company PCCW's chief technology officer Paul Berriman.
The announcement comes as Telecom releases shareholder information about the proposed demerger, which investors still have to approve.
The phone company won the lion's share of the government's broadband rollout after proposing structural separation in a bid to shed the heavy regulatory burden of operating a copper-line network monopoly, and win tax-payer funding to build a nationwide fibre network.
That bid was successful, and Chorus won $929 million of the $1.35 billion on offer from the government to roll-out an ultra-fast broadband network.
Chorus expects it will have to spend $470 million and $670 million of its own money over the next eight years on construction.
Once the split is complete, New Telecom will be the bigger of the two companies, with adjusted pro-forma earnings before interest, tax, depreciation and amortisation of $1.125 billion on $5.1 billion of sales in the 12 months ended June 30, while Chorus made $676 million on $1.1 billion of revenue.
The shares fell 2 per centfor to $2.465 in trading yesterday, and have climbed 16 per cent this year.
