The action drama starring Maggie Q has been struggling since its move to 9pm on Friday nights, dropping to a low 0.2 18-49 demographic rating and just 793,000 viewers two weeks ago.
The network has decided to move it back an hour to its previous slot of 8pm on Fridays.
Nikita's first airing in the new slot will be on November 30, according to advanced TV listings. It will be followed by a repeat of superhero series Arrow.
The show - based on the French film Nikita, the remake Point of No Return, and previous series La Femme Nikita - is currently in its third season on The CW.
