Fiji have extended their lead atop the World Sevens Series to five points after overcoming New Zealand 21-7 to defend their Hong Kong title.
Pita Ahki's try gave the All Blacks Sevens an early lead in the final before Jerry Tuwai levelled the scores at 7-7 before the break.
Fiji then took control in the second spell when Kitione Taliga and the returning Semi Kunatani, who was named man of the match, dotted down to seal victory.
New Zealand were forced to play two periods of extra time in their semi final victory over South Africa but coach Sir Gordon Tietjens played down any suggestion his squad was tired, insisting Fiji were simply too good.
"I'd never use that as an excuse but they obviously worked very very hard in that semi final and the final wasn't to be. I'm certainly not looking back at that but it might have played a minor role perhaps. We were competitive in the final but just not good enough."
Samoa missed out on the Cup quarter finals and were upset 19-14 by Scotland in the bowl semi finals.
