The Opposition suspended its plan to hold nationwide street protests following passage of the Election Laws 2016.
Cord had planned for mass action, in quest to suspend implementation of the laws.
However, during Opposition's mega meeting at the Bomas of Kenya in Nairobi, Cord leaders asked Kenyans to come out in large numbers and register as voters, before going to the streets for protests.
This follows the second phase of the Mass Voter Registration exercise, by the Independent Electoral and Boundaries Commission (IEBC), set to kickoff January 16. IEBC targets six million new voters in the drive.
"To our supporters, we will deal with election Laws - we promise you that - but you must all go out, in every town, village, home, church, school, bus stop every single day and not rest until everybody you meet is a registered voter to send a mass message to Jubilee that they must go home!'' said Cord leader Raila Odinga.
''It has to be done. It has been done elsewhere. It will be done here with your help and the backing of a united opposition,'' he added, Wednesday.
