A win will all but secure New Zealand a semifinal berth.\xa0
Thunderstorms are forecast during the course of the match which starts at 9.30pm.\xa0
If the game is called off, the Black Caps would need South Africa to beat Afghanistan tomorrow and England to defeat Pakistan on Saturday to reach the semi-finals.\xa0
Coach Gary Stead told Mike Hosking that the forecast is getting better day by day, so he\u2019s pretty sure they\u2019ll be able to get some sort of match in.\xa0
He said that they know they have to beat Sri Lanka, and if they do that there\u2019s a good chance they\u2019ll qualify for the semifinals. \xa0
