The White Ferns have been crushed by 232 runs in the third and final Rose Bowl one-day international in Brisbane on Wednesday.
Chasing Australia's mammoth target of 325/5, NZ were bundled out for just 93 in 27 overs.
The victory seals a 3-0 series sweep for Australia to go with their 2-1 win in the Twenty20 internationals.
Batting first, the hosts bludgeoned the NZ attack from the opening over.
Captain Rachael Haynes led the way with 96 runs, combining with Alyssa Healy (87) for a 144-run first-wicket partnership that set the foundation for their imposing total.
Spinner Amelia Kerr was the lone bright spot with the ball, finishing with figures of 3-50.
In response, five quick White Ferns wickets in the first 15 overs essentially ended the contest, including the key scalps of Amy Satterthwaite (41), Sophie Devine (0), and Kerr (0).
That momentum continued for Australia, who claimed the final five wickets for just 39 runs to complete an easy day at the office.
