Remarkably, West Indies captain Darren Sammy won the pre-match coin toss for the sixth match in a row. He decided to field first, and so England will post a total to chase in Kolkata.
England will contest the World Twenty20 final after Jason Roy's career-best knock and some brilliant death bowling overwhelmed New Zealand.
The Black Caps came into the semi-final with a 100 per cent record but were blown away by seven wickets with 17 balls remaining in Delhi.
They had been kept to a below-par 153 for seven by the constricting efforts of Chris Jordan and Ben Stokes and then looked on as Roy crashed 78 from 44 deliveries.
Roy hit 11 fours and two sixes, scoring more than half of the target on his own, before Joe Root (27 not out) and Jos Buttler (32 not out) finished off with three maximums in four deliveries.
England will play either hosts India or the West Indies in this Sunday's final.

England collapsed haplessly and then received no mercy from a rampant AB de Villiers at the Wanderers as their tour of South Africa ended with a nine-wicket trouncing and 2-0 Twenty20 series defeat.
From 157 for three in the 17th over, England were bowled out for 171 with two balls of their scheduled innings unused - after Jos Buttler (54) and Eoin Morgan had set course for far better.
De Villiers (71) then wasted no time putting England's efforts into brutal context, with South Africa's fastest-ever Twenty20 50 from 21 balls, as Morgan's tourists lost a fifth successive international white-ball match in the space of 13 days.

England seamer James Anderson is on track to play in the second Test against South Africa in Cape Town.
Anderson was ruled out of the series opener in Durban due to a calf strain that has been troubling him since the start of the trip.
But England have been easing their record wicket-taker back into action over the course of the past week, with Anderson sending down regular spells in the nets.
On Wednesday morning the 32-year-old sent down the equivalent of six overs in the middle, watched by bowling coach Ottis Gibson, and got through the session without any concerns.
England fly to Cape Town on Thursday, with the Test starting on January 2.
Nick Compton and James Taylor came together to lift England after a difficult start to the Boxing Day Test against South Africa.
The tourists had been 12 for two and 49 for three after being asked to bat on a rain-affected morning at Kingsmead, Dale Steyn dismissing both openers and Dane Piedt pinning Joe Root lbw with his first delivery.
But Durban-born Compton, returning to Test cricket after two-and-a-half years in the cold, offered a steady hand at number three as he and Taylor took the score to 121 for three at tea.
