Ambrose Curtis and Beaudein Waaka return to the All Blacks Sevens squad named for the Las Vegas and Vancouver legs of the HSBC World Series.
Joe Webber, Sam Dickson, Lewis Ormond, Teddy Stanaway and Rocky Khan were all unavailable for selection due to injury, while Regan Ware's name is also missing from the 14.
Curtis, who last started for the All Black Sevens in 2015, having 17 tournaments to his credit, played for the Maori All Blacks on their Northern Hemisphere tour at the end of last year and has been on a training contract with the Blues over the summer. He appeared in the Brisbane Tens less than a fortnight ago.
Waaka last appeared for New Zealand at the Dubai leg of the World Series in December.
"It's great to have a largely settled squad to take to North America. The new players who debuted in the Wellington and Sydney tournaments have impressed thus far, so it's good to keep giving them game time and experience," said All Blacks Sevens head coach Scott Waldrom.
