New Zealand suffered one of the biggest upsets in sevens history when they were beaten 14-12 by Japan.
In a double blow for the team Sonny Bill Williams has been ruled out of the tournament with a partial Achilles rupture. He has been replaced by Sione Molia.
Joe Webber also left the field with a suspected dislocated shoulder.
The New Zealanders struggled to get possession in the first half of the pool match against Japan - with the score 7-7 at half time - and Japan defended well after the break.
Scott Curry and Akira Ioane scored tries for New Zealand.
New Zealand's next pool game is against Kenya at about 8.30am - and they need to win to keep their Olympic campaign on track. A loss would mean the team would have to rely on other results to make it through to the quarter-finals.
