Ryder told New Zealand's selectors Monday he is unvailable for personal reasons for the A team's tour which involves two limited-overs matches against Ireland and others against the UAE and Afghanistan.
New Zealand Cricket said in a statement it "respects Jesse's decision" to withdraw.
The tour is part of the process which will lead to the Dec. 8 announcement of New Zealand's preliminary World Cup squad.
Ryder yesterday failed to join his Otago provincial team on a flight to Christchurch for a domestic Twenty20 match, only advising team officials later of his unavailability.
