Allrounder Devine will remain as the captain in One-Day Internationals (ODIs).
"With captaincy comes an additional workload that, while I’ve enjoyed taking on, can also be challenging at times," the 34-year-old said in a statement.
"But I won’t be around forever, so I think stepping away from captaining one format at a time gives the next leaders time to find their feet."
Devine, the first cricketer to score six consecutive fifties in T20 Internationals, has captained New Zealand in 56 matches in the format, winning 25 of them.
