The inclusion of Seifert provides the Black Caps with another top-order option in their batting line-up and the 30-year-old was in good form himself during the T20I portion of the series against Pakistan.
Seifert was the leading run-scorer across the five-match series with 249 runs and Stead believes he can replicate these efforts in the 50-over game.
“With several new faces in this squad it’s great to be able to call on a player of Tim’s experience,” Stead said.
“He’s in good form after a great T20 series and he provides another strong top-order batting option heading into an important match tomorrow.”
New Zealand squad for second ODI against Pakistan: Tom Latham (c), Muhammad Abbas, Adi Ashok, Michael Bracewell, Jacob Duffy, Mitch Hay, Nick Kelly, Daryl Mitchell, Will O’Rourke, Ben Sears, Tim Seifert, Nathan Smith, Will Young
