Campbell was two under par after his initial seven holes. Then he disintegrated.
He signed for a five over par 77 and followed that up yesterday with a six over par outward nine and an eventual 79 to kneecap his chances of weekend play.
Subsidiary poster boy Danny Lee did not even front because he decided to go after Race to Dubai points in the Hong Kong Open this week.
Another poster boy, former NZ Open champion Smail, began with a scrappy 77 including a triple bogey, but repaired a fair chunk of that damage yesterday.
He ended with a 68 with the highlight an eagle on the sixth when he holed his second shot to the par four in a rollicking outward half of 32.
Amateur Fox opened up with a par round but emulated Campbell with a six over par outward half yesterday to leave him in danger of missing the cut. However Fox birdied the last to arrest a scrappy round and give himself another chance this weekend.
