Abdul Hanan Himat, head of the Taleban's Bakhtar news agency, earlier quoted Taleban Information Minister Qudratullah Jamal as saying in Kabul that she had already been freed.
A Pakistani official in the northwestern city of Peshawar had told Reuters the handover would take place at the Torkham border crossing point near the Khyber Pass.
Zaeef said he had invited a British diplomat to his house to discuss procedures for Ridley's release on Monday. The Taleban's reclusive supreme leader, Mullah Mohammad Omar, had issued an order to free Ridley, officials said on Saturday.
Ridley, 43, was picked up with two Afghan guides near the eastern Afghan city of Jalalabad on September 28 while dressed in an all-enveloping burqa, which has only a mesh for the eyes.
The hardline Taleban, threatened with US military strikes for refusing to hand over fugitive militant Osama bin Laden, had been investigating whether Ridley was really a journalist or a spy.
The decision to release her came a day after British Prime Minister Tony Blair made a brief stop in Islamabad for talks on the Afghan crisis and the global war on terrorism with military ruler General Pervez Musharraf.
"We, after our contacts through diplomatic channels, decided to release her," Jamal was quoted as saying by Qatar's al-Jazeera television channel.
The fate of Ridley's guides was not immediately known, but they could face severe punishment.
