In the chase, Kerr and Suzie Bates put on 47 for the second wicket which looked to give the White Ferns a chance at 54-1 at the midway mark before they lost nine wickets for 34 runs.
Australia’s Megan Schutt finished with 3-3 from 3.2 overs including 18 dot balls. New Zealand haven’t beaten Australia since March 2021 while this was their fourth straight World Cup defeat to Australia.
“We needed to have a good start and we let the run rate creep up too much. By the ten over mark it was up over 10-an-over,” New Zealand captain Sophie Devine said.
“At the halfway mark we thought the wicket played better than we thought it would. But we got ourselves into a bit of a hole. When we were bowling we strayed a little too far from the stumps and that’s where we had been good against India.
“In the field we were a little sloppy. With the bat we need to play some more courageous shots. We’ve still got two games to go. We don’t want to get too carried away with run rate. Sri Lanka is our next big game.”
