Finn Allen smashed the fastest century in T20 World Cup history as New Zealand crushed South Africa by nine wickets to reach Sunday's final. The explosive opener raced to 100 not out from just 33 balls, including 10 fours and eight sixes, as the Black Caps chased down 170 with 43 balls to spare.

Allen's blistering knock surpassed Chris Gayle's 47-ball century from 2016 by 14 deliveries and ranks as the joint third-fastest in men's T20 internationals. Tim Seifert provided strong support with a 58 off 33 balls, as New Zealand's openers put on 117 runs in just 55 balls. South Africa had earlier been rescued from 77-5 by Marco Jansen's 55 not out, which included five sixes in an unbeaten 55 off 30 balls.

The Proteas' collapse marked another semi-final heartbreak in major tournaments, extending their reputation as chokers. Despite entering as favourites after an unbeaten run through the group and Super 8 stages, South Africa's top order failed for the second consecutive match. New Zealand will now face either India or Australia in the final, with Allen's record-breaking performance establishing them as serious title contenders.
