Kiwi Steven Alker, who carded rounds of 69 and 71, and countryman Tim Wilkinson (72 and 68) both finished at one-over and look set to miss the cut, which was projected to be at one-under.
Meanwhile, at the Mizuno Open on the Japan Tour, Michael Hendry remains in a share of the lead after the second-round, despite carding a one-over 73 yesterday.
The North Shore professional opened with a nine-under 63 on Thursday but couldn't keep up that pace yesterday as the field caught up with him. He holds the lead with three others, including Australian Scott Strange, at eight-under.
The top four players from this week's tournament get direct entry to The Open Championship in Scotland in July.
At the Lanhai Open on the PGA Tour China circuit, Josh Geary carded an even-par 72 yesterday to sit in a share of second place after the second round. Geary and two others are one shot back from leader J.H. Wang.
Kiwi Daniel Pearce is one shot back from Geary at four-under in a tie for fifth, while Waikato professional Mathew Perry is at two-over in a share of 35th.
Geary leads the order of merit in China having won the Buick Open last month.
