Left-handed batsman Umar Amin was drafted into the ODI squad in place of all-rounder Shoaib Malik who had sustained an injury during the fourth ODI against New Zealand in Hamilton.
"Shoaib Malik is doing better after sustaining a delayed concussion during the last ODI in Hamilton. However, he has not made a full recovery to be available for selection in the Wellington ODI," said Pakistan team physiotherapist Vib Singh.
Amin is already available in Wellington as he is a part of the T20 squad.
Pakistan have lost the first four ODIs of the five-match series against Kiwis while the fifth is scheduled to begin in a few hours.
