The man was taken to hospital after being injured trying to jump a barrier to get onto the ground where the Kiwis were knocked out of the Rugby League World Cup by Fiji, police said in a statement.
Fiji dominated the first half in Wellington but were too slow and laboured to break the Kiwis down as they failed to add to Apisai Koroisau's penalty.
Fiji face reigning champions Australia next.
No side scored more points than Fiji in the group stage and they thought they had taken a fifth-minute lead through Brayden Williame, only for replays to show the Catalans Dragons player had failed to ground the ball.
Fiji have reached the last four on two previous occasions but were massive underdogs to make it in 2017 after being drawn with the Kiwis.
