The first chance of the second half fell to the away side, but Krul was on hand to save an effort from Chris Eagles with his legs.
Having struggled in the final third for large parts of the match, hosting Newcastle broke the deadlock courtesy of an individual effort from Ben Arfa 16 minutes from time. The French midfielder picked up possession just inside the Bolton half, before weaving his way into area and shooting low into the left hand corner of the net.
The victory was made certain in the 83rd minute thanks to Cisse, who headed in a cross from Shola Ameobi. That strike took his tally for the club to ten since joining from Freiburg in January.
The Magpies will drop back down to sixth if Chelsea defeat Fulham later today.
