Sri Lanka have gone from the brink of the Women's T20 World Cup knockout stage to out of the tournament.

New Zealand's huge 102-run win over Sri Lanka on Sunday in Paarl instead put them in position to follow defending champions Australia into the semi-finals from Group 1.

The Kiwis moved second behind Australia, but that could also be temporary as a win for South Africa over Bangladesh on Tuesday would see the hosts snatch the semi-final place.

New Zealand gave themselves a chance with a dominant performance to end Sri Lanka's participation.

Bernadine Bezuidenhout (32), Suzie Bates (56) and Amelia Kerr (66) all made big contributions at the top of the order to see New Zealand to an impressive 3-162 after choosing to bat first at Boland Park.

Sri Lanka, who would have been into the last four with a win, collapsed under the pressure and were all out for just after being one batter down with Achini Kulasuriya not coming out because of an injury.

New Zealand legspinner Kerr took 2-7 off 2.5 overs.

Fast bowler Lea Tahuhu returned figures of 2-12 in four overs to join Australia's Megan Schutt as the joint-leading wicket-takers at the tournament with eight scalps.
