The side features one new player in Akira Ioane, who was a star performer for Auckland at the National Sevens over the weekend where the team came second to Wellington.
The 18-year-old finished school at Auckland Grammar only last year and it will be his first trip to Vegas - not that he will get a chance to see the sights.
It will be a lesson in professional rugby and how to win a tournament for the youngster Tietjens says reminds him of Zinzan Brooke.
"He is someone we want to grow as a sevens player. He has all the attributes and the skill set of a fine rugby player. He's exciting, very fast, very skilful and it will be real challenge for him his first tournament, but I am sure he will thrive on that.
"He is somewhere around a 4.81 standing 40 (metres), which is very fast. He has learnt so much in these last three days that it was a no-brainer really as he has played himself into a situation where I want to see what he has got.
"It is also about adding depth looking forward to 2016. You have an 18-year-old here and slowly bring him in with the experienced players."
The All Blacks Sevens have not won in Las Vegas and this will be the fifth year the US tournament has been held in the gambling mecca.
"We have played consistently well there so it's not that we don't play well there, it comes down to those defining moments that decide whether you win or lose," Tietjens said.
"We have to use different tactics because there is not as much width on the field so there is a lot more contact and I have picked a side that is very strong and very big and hopefully they can do the work for us."
