The main concern for the Black Caps heading into the tournament is the top of the order. In the recent 2-0 defeat to South Africa, James Neesham was tested alongside Martin Guptill with neither batsmen firing in the two New Zealand innings.
As expected, the squad doesn't include Otago opener Jesse Ryder who missed the New Zealand A tour of the UAE due to personal reasons.
The basis of the squad offers plenty promise for New Zealand fans. Daniel Vettori (277 ODIs), Brendon McCullum (232), Mills (166) and Ross Taylor (137) all have stacks of experience while the likes of Corey Anderson and Mitchell McClenaghan have the game-changing potential to star in the tournament.
The likes of Kane Williamson, Southee, Nathan McCullum and BJ Watling have all been around international cricket long enough to know what is needed to win a one-off tournament, while younger squad members Milne, Henry and Latham might be in a better position in four years' time to make an impact at a World Cup but wouldn't surprise if they were included in the 15-man squad.
All eyes will be on these 30 players over the next 30 days.
