Telecom recently said it's considering structural separation of its network and retail businesses because of the Government's broadband plan.
Crown Fibre Holdings has announced Telecom is one of the 14 parties short-listed for the broadband roll-out.
Communications Minister Steven Joyce says a structural separation of Telecom would be a major change to the telecommunications industry.
And he says it would impact on key elements of the regulatory regime governing the industry.
Submissions close on 15 October.
