The match was reduced to 25 overs a side after rain in Tauranga.
Australia posted 149-7, with White Ferns off-spinner Leigh Kasperek taking three wickets in five balls to disrupt their progress.

New Zealand slipped to 51-4 and 77-6 in their chase, Megan Schutt taking 2-22 as the hosts struggled for runs.
Georgia Wareham also took 2-25 on her one-day debut as Australia extended their record-breaking winning streak to 24 matches.
