The Black Ferns Sevens have failed to fire in Sunday's Sydney Sevens final, limply falling 31-0 to Australia.
So dominant through their pool play and in Saturday's matches against Ireland and Canada, the Kiwis collapsed at the final hurdle.
They conceded five tries to none and never looked likely to respond, despite the attacking presence of Portia Woodman and Michaela Blyde.
Giving up first-half tries to Shannon Parry and Charlotte Caslick, a yellow card to Kiwi Tyla Nathan-Wong early in the second half didn't aid their cause.
Australia then romped home in the second stanza through Ellia Green, Evania Pelite and Emma Sykes tries to break a five-match losing streak against New Zealand and win their first trans-Tasman Sevens clash since the 2016 Rio Olympics final.
