New Zealand stormed into the final of the ICC Men’s T20 World Cup after crushing South Africa by nine wickets in the first semi-final at Eden Gardens.

Chasing 170, the Black Caps raced to the target with just one wicket down, powered by a blistering century from Finn Allen, who struck 100 off 33 balls — the fastest century in T20 World Cup history.

New Zealand captain Mitchell Santner had earlier won the toss and elected to field.

South Africa posted 169 for eight in their 20 overs. Marco Jansen remained unbeaten on 55, while Dewald Brevis scored 34 and Tristan Stubbs added 29. Captain Aiden Markram made 18, Quinton de Kock 10 and David Miller six.

For New Zealand, Matt Henry, McConchie and Rachin Ravindra picked up two wickets each to restrict the Proteas.

In reply, Allen dominated the chase with a stunning display of power-hitting. He was well supported by Tim Seifert, who scored 58 as New Zealand completed the chase comfortably.

South Africa had entered the semi-final with a psychological edge, having beaten New Zealand in the group stage and holding a superior overall T20 World Cup record in head-to-head meetings.

However, New Zealand maintained their strong knockout pedigree against the Proteas in ICC tournaments.

The second semi-final between India and England will be played at Mumbai’s Wankhede Stadium.
