"We saw against India earlier this season the power and range of shots that Tom possesses. His adaptability also means he can feature in a range of batting positions," coach Mike Stead.
"He led an inexperienced T20 squad to Bangladesh in 2021 and we were really impressed with his leadership of that group during a COVID bubble tour."
Former South Africa under-19 skipper and top order batsman Chad Bowes and seamer Henry Shipley, who made his one-day international debut in January, are in line to win their first T20 caps after being included in the squad for both series.
New Zealand play Sri Lanka in Auckland, Dunedin and Queenstown in the first week of April before three T20s against Pakistan in Lahore and another two in Rawalpindi from April 14th-24th.
Stead will skip the Pakistan T20s, leaving Shane Jurgensen to lead the team, but return to the helm for the subsequent five one-day matches against the hosts.
Squad: Tom Latham (captain), Chad Bowes, Mark Chapman, Matt Henry, Ben Lister, Adam Milne, Daryl Mitchell, Jimmy Neesham, Rachin Ravindra, Tim Seifert (not Pakistan series), Henry Shipley, Ish Sodhi, Will Young.
Pakistan series only: Dane Cleaver, Cole McConchie, Blair Tickner.
