Corey Anderson included as specialist batsman in T20I squad
Anderson was sent home from New Zealand's tour of England earlier this year with a “bone stress related injury to his lumbar spine”.
The 25-year-old, who has 72 international wickets across the three formats has not yet resumed bowling at the domestic level and will feature only as a batsman.
The squad also sees the return of Grant Elliott, who has recovered from a broken arm which he sustained during a net practice session in November.
The team will be led by Kane Williamson and Brendon McCullum has not been named in the squad as he will not be taking part in the World T20 in India next year.
James Neesham and Nathan McCullum are unavailable due to injury and Matt Henry misses out on selection alongside Tom Latham.
Despite the fact that Anderson will not be bowling in the T20Is, New Zealand coach Mike Hesson is confident that the left-hander will be very effective even as a specialist batsman.
"It's been a long process for Corey, but we've been happy with his recent progress and the fact he's managed to string a few games together for the Northern Knights.
“He's getting closer to bowling, but we'll be taking a precautionary approach.
“We've seen how dynamic a batsman he is and can threaten any bowling attack in the world.”
Speaking about Elliott’s inclusion, Hesson said, “Grant brings a lot to the squad and has experience in pressure moments, which is key to batting in the middle order in Twenty20.”
Henry, who took eight wickets in the first two ODIs against Sri Lanka has been dropped while George Worker also misses out for the final two games.
The two T20Is between New Zealand and Sri Lanka will be played in Mount Maunganui and Auckland on the 7th and 10th January respectively.
