"Despite Martin Guptill being ruled out, we've decided to name just two rather than three additional players, taking the squad to 13.
"We're confident that, with the As on the ground over there, we have adequate cover."
Anderson, who last played for the Black Caps at the 2017 ICC Champions Trophy, said it was always an exciting moment getting that call.
"It's obviously been a long road back and after the surgery there were some long tedious days," he said.
"But this is what the rehab is for and to be picked again is a great feeling."
Larsen said returning to the international scene was an important step for the talented 27-year-old all-rounder.
"Corey's had a really good winter playing in the UK and training back at home, and has shown on the New Zealand A tour he's more than ready for the rigours of international cricket."
The final game of the New Zealand A one-day series is on Friday, after which Larsen and coach Gary Stead will name the final additions to the Black Caps ODI squad.
Fresh off his century in the second round of the Plunket Shield, Central Stags wicket-keeper Dane Cleaver has been called up to the New Zealand A team as cover for Tom Blundell, who has a groin strain.
Blundell has undergone a scan and will be monitored over the next week with an eye to returning for the second First-Class game against Pakistan A, before joining the Black Caps for the three-match Test series, starting in mid-November.
