Taibu turned out for Namibia on Sunday in Windhoek against Limpopo in a South African provincial tournament, which runs until next March.
He can play for Namibia while remaining a Zimbabwean citizen as the competition is not given full international status.
''I'm going through the contract at the moment and should sign it in the next couple of days,'' the 23-year-old right-handed batsman told BBC Sport.
''I wanted to be away from the politics in Zimbabwean cricket and at the same time remain active in competitive cricket, so Namibia is good for me at the moment.''
Taibu turned his back on Zimbabwe last November after 24 Tests and 84 one-day internationals, accusing the country's cricket board of financial mismanagement.
He had stints of club cricket in Bangladesh and England before moving to South Africa, where he tried to qualify for the Proteas.
Taibu, however, did not rule out returning to his homeland, saying, ''It's a possibility, but if nothing happens soon I won't be going back to play for Zimbabwe.''
