The New Zealand 7s team pulled off a great escape to defeat the Vodafone Fiji 7s team 24-21 in their quarterfinal match this afternoon.
With about 10 seconds left on the clock, Fiji was leading New Zealand 21-17.
But a decision made by Fiji to kick for chase came back to haunt them as New Zealand quickly gained possession.
After patient build‑up and great team play there was a break by Tim Mikkelson which allowed Sione Molia to score the winning try.
Iopu Iopuaso had scored the opening try in the match and this came as a double blow for Fiji because Kalione Nasoko was yellow carded.
Fiji scored its first try with six-men on the field when some great team play led by Jerry Tuwai allowed Sevuloni Mocenacagi to score in the corner.
