The tour will play an important role in firming up the final spots in New Zealand's T20 World Cup squad.

"Michael has faced a long period on the sideline and it's exciting to see him back playing cricket again," selector Sam Wells said. "The fact he's back playing at a high level after an achilles rupture is testament to his hard work and application.

"He's a well-respected leader and has captaincy experience for Wellington along with New Zealand A and New Zealand XI teams, which we believe holds him in good stead to lead the group in Pakistan."

"Tim is still very early in his domestic career but his natural ability and explosive power was on full display this season," Wells said. "Combined with his outstanding fielding, we believe he has a skill-set that's well suited to the format.

"We've been delighted with Will's early efforts in international cricket, in both the formats he's played so far. This tour will be an excellent chance for him to test his skills in foreign conditions."
