All-rounder Corey Anderson has left Mumbai and is flying home from the Indian Premier League with a finger fracture.
Fast bowler Adam Milne's heel injury has also ruled him out of the IPL.
Both players' involvement with the national cricket team's tour of England appears to be in doubt.
A New Zealand Cricket spokesman says they're waiting for the pair to arrive home before commenting further.
Milne missed the semi-final and final of the recent World Cup due to the injury, which hasn't healed enough for him to play for the Royal Bangalore Challengers.
