"Ambrose has earned his spot in the starting 12. He brings experience from previously playing for the All Blacks Sevens and, with his recent time with the Blues, is a good addition to the team.
"I'm looking for the team to step up and play with improved discipline. Again in Las Vegas we showed glimpses of the squad we can be, but we let ourselves down in the games that mattered with simple errors. To move past the semifinals and take out a tournament we need to play without mistakes in every game.
"We go into the tournament keen to make our first final of this series. We are first up against Russia, who are improving, Scotland is only a couple of places behind us on the overall series standings and have shown they can win against the top teams, and Canada will be keen to impress at home. So we are going to have to work hard on day one to earn our spot on finals day."
That New Zealand-Canada clash is the climax to day one, so the 35,000 crowd should be in full voice by then.
New Zealand are fourth on the overall standings, but trail leaders South Africa by 36, so at the halfway point of the World Series, they may be playing for second of third.
