After three legs of the Sevens World Series, New Zealand are in third behind Fiji and leaders South Africa. They must finish in the top four in the series to earn automatic qualification for the Olympics in Rio de Janeiro next year.
"We are very much looking forward to Wellington as the city really turns it on for all the teams. It's always very special to play in front of a home crowd as we only play in New Zealand once a year," Tietjens said.
"This is also an important tournament for us given our current position in the series. We won here last year so we will be working hard to do our best in front of our fans."
New Zealand sevens squad: Tomasi Cama, Dylan Collier, Scott Curry, Ambrose Curtis, Sam Dickson, DJ Forbes, Jack Goodhue, Josh Gordon, Rieko Ioane, Gillies Kaka, Tim Mikkelson, Lote Raikabula, Sherwin Stowers, Murphy Taramai, Beaudein Waaka, Joe Webbe
