During the release of results for the first quarter of 2018, Morrow hinted that NBN Co was thinking of releasing speed estimates in the event that internet service providers did not do so.
But Fairfax Media reported on Thursday that Morrow was now back-pedalling on this position, claiming that it could confuse customers.
He told the Senate Environment and Communications Legislation Committee that NBN Co had looked carefully at the "mass confusion" about services that were being provided to end users.
Morrow said: "Part of the reason [why consumers are confused] is they think NBN Co is their entire provider.
"I do not want to propagate confusion ... where the consumer is confused about who their go-to company is for their telephone and internet requirements."
He said that the agreements that NBN Co had with RSPs would have to be examined by lawyers before any speed information could be released.
"If there are no restrictions, and if the RSPs do not publish the information, then I intend to," Morrow said.
But he was not willing to give the committee any more information, claiming that he did not know if this could take place before July next year.
