AZ signed the 23-year-old on a season-long loan deal from Club Brugge in the summer as a replacement for Alireza Jahanbakhsh.
However, Rotariu failed to impress and only made eight appearances for the club in the first half of the season. With Calvin Stengs back to full fitness, AZ have allowed Club Brugge to end his loan early.
Club Brugge have now sold the forward to FC Astana in Kazakhstan.
