Canterbury seamer Matt Henry has been brought into the Blackcaps squad for the second test against Pakistan at Hagley Oval starting on Sunday.
Henry replaces Neil Wagner, who's recovering from undisplaced fractures in both the fourth and fifth toes of his right foot, sustained in the first test at Bay Oval.
Wagner’s recovery is expected to be approximately six weeks.
NZ coach Gary Stead says Henry brings test experience and local knowledge to the squad.
"Matt has been in good form with the ball having recently taken 6-53 for New Zealand A against the Pakistan Shaheens (A side) in December," Stead says.
"We’re still a couple of days out from the test, so need to take a look at the surface while also assessing our options for best-possible team make-up."
Henry is the only change from the squad named for the first test, where he will battle with Mitchell Santner and Daryl Mitchell for the final two spots in what should be an unchanged side.
There is a lot riding on the second test for the home side, who must win to keep alive their hopes of making the test championship final, with India and Australia currently sitting in front of them.
Williamson's Blackcaps are currently the provisional No.1 test team, and a win against Pakistan in Christchurch would cement their spot at the summit.
