The All Blacks Sevens will need luck on day two if they are to retain their Sydney trophy after being thrashed by Fiji 26-5.
The Fijians scored three-unanswered first-half tries to open up a 21-0 lead at the break.
The Kiwis hit back early in the second half through Regan Ware, but they couldn't recover from the bad first half.
Fiji scored a late try through Waisea Nacuqu to seal the 21-point victory.
The loss means they will need Fiji to lose to Wales to have any chance of making the semi-finals.
Earlier, the All Blacks Sevens opened their Sydney campaign with a dominant 54-5 win over Wales on Saturday.
The New Zealanders ran in eight tries to one to continue their momentum from their two consecutive title wins in Cape Town and Hamilton.
Caleb Clarke and Salesi Rayasi both ran in a brace of tries, while Joe Goodchild crossed for the Welsh.
Their last pool game is against Kenya at 3:41pm (NZT) on Sunday.
