Mr Williamson passed the offer on to Telecom, which had been privatised. "NZ Telecom chose, for whatever reason, not to do it," he said.
The Telecom chairman at the time, Peter Shirtcliffe, said he could not recall the proposal being put to the board. The board would have been unlikely to go into such a deal because of the pressure of restructuring the formerly state-owned entity.
Mr Williamson said Mr Keating "pulled the plug" on a joint transtasman aviation market in 1994. It would have allowed Air NZ to fly to, within and beyond Australia on the same basis as an Australian firm.
Mr Williamson said Mr Keating's decision came after pressure from News Corp's Rupert Murdoch, whose group then owned half of Ansett.
