Brendon McCullum and his men will face one of their biggest CWC challenges immediately as Sri Lanka confirm the return of deadly bowler Lasith Malinga.
Arguably, Malinga is one of the hardest bowlers for batsmen to play against in world cricket.
At the death and the top of the innings, Malinga is almost impossible to build a decent run rate against and in this forms what will be one of the biggest challenges that the Blackcaps batsmen will face throughout the Cricket World Cup.
Malinga could be the bowler that ruins the party surrounding the World Cup by ripping through the Blackcaps batsmen in game one.
The threat will be present no matter where the Blackcaps are in their innings.
Blackcaps bowlers must take consistent wickets. For the batsmen, chasing a total over 300 will be tough against a side that possesses Lasith Malinga as part of their attack, even if the conditions are perfect for batting.
The Blackcaps showed good mental headspace with the bat during the recent series against Sri Lanka and Pakistan, but the question of how they will approach a bowler like Malinga is difficult to answer.
A batsmen like Martin Guptill and his frequent indecision early on at the crease is perfect for Malinga.
Sri Lanka would be encouraged to use him at the beginning of an innings, not just at the depth.
The Blackcaps batsmen have to bat without fear, take risks, and back themselves to find gaps in the field because Lasith Malinga has the potential to rip his way through the batting lineup at a moments notice.
