Steve Niles, who created the graphic novel on which last year's film was based and wrote the original screenplay, will return to writing duties alongside Ben Ketai.
The original story starred Josh Hartnett and Melissa George and centred on a remote Alaskan town that gets overrun by blood sucking villains during a month of complete darkness. Columbia Pictures released in North America last year.
It is believed the sequel will focus on the lead female character as she wreaks revenge against her supernatural foes. Mandate International declined to comment.
