New Zealand have vowed to win the Wellington Sevens tournament for Toby Arnold who is facing nine months on the sidelines after seriously injuring his knee.
Arnold was hurt in the opening minutes of New Zealand's first game against Scotland on day one of the fourth leg of the HSBC Sevens World Series and scans have confirmed serious ligament damage which will require surgery.
"Toby was obviously devastated to be told," said New Zealand Sevens coach Gordon Tietjens.
"He's very, very down and you've got to feel for him.
"You want to play in this tournament. He was part of this tournament last year. We've got to go out and win it for him. That's what we've got to do."
New Zealand are certainly on track to repeat their Wellington title success of last year after going through pool A unbeaten.
A DJ Forbes hat-trick helped them overcome a shaky start against Scotland to win 29-7, while Bryce Heem, Tomasi Cama and Hosea Gear all bagged doubles as they cruised to a 54-0 victory over Japan.
Even the presence of streaker, who tackled Samoan player Alatasi Tupou, could not put them off their stride as they went on to win their final match of the day 19-5 to set up a Cup quarterfinal showdown with surprise package France, who were runners-up in pool D.
"I was quite amazed the guy actually got through the barriers," Tietjens said of the pitch invader.
"But it happens in sport sometimes. The streaker is going to find himself in hot water. He won't be allowed in tomorrow or for a long, long time.
"He could have got himself badly injured and he could have injured one of the players as well. So it's not good to see that sort of thing happening."
While most people would not have expected the French to make it into the Cup last eight, Tietjens said they were a more than capable side.
"They will be tough. We've played them in the past and they've won an IRB series tournament so you never take them lightly," he said.
"We've seen what they can do. We've seen them at the World Cup."
Canada topped pool D after beating the French in their opening game then following that up with a narrow loss to Australia and an impressive 21-14 win over Kenya.
They will meet Samoa in the Cup last eight.
South Africa were the only other team to go through day one unbeaten after keeping the United States and Cook Islands scoreless then defeating England, the 2009 Wellington champions, 14-10 to take top spot in pool B.
South Africa however, face a tricky Cup quarterfinal against pool C runners-up Fiji.
A shock loss to Pacific Island rivals Tonga in their second game meant they had to beat Wales – which they did comfortably 19-0 - to take second spot.
England will meet Tonga who topped pool C.
The quarterfinal bowl matches will see Scotland play Kenya, who were the most disappointing of the day one teams, Wales take on the United States, Australia face Japan and the Cook Islands play Argentina.
