"The way Mark's played against one of the best T20 bowling attacks in the world has been nothing short of outstanding," New Zealand head coach Gary Stead said. "His match-winning knock in the fifth and deciding match was particularly special and we're happy to have someone in such strong form added to our ODI squad."
Tom Blundell and Henry Nicholls will join the squad in Rawalpindi for the ODIs, while Dane Cleaver, who was part of the T20Is, will return home.
The ODIs begin in Rawalpindi on April 26, with the last three matches set to take place in Karachi. The final game takes place on May 7.
