Some new faces in All Blacks 7s
Trael Joass, Andrew Knewstubb, Vilimoni Koroi and Tone Ng Shiu will make their debut in front of home fans.
Waldrom said selections were based on performance at the recent National Sevens tournament.
"We said that the guys performing well would be the ones rewarded with selection. We are confident that this squad contains the best sevens rugby players in the country at the moment.
"This is a team based on form, and it shows that exciting talent coming through can put their hand up and be successful with national selection.
"It’s exciting to put Trael, Andrew, Vilimoni and Tone into the All Blacks Sevens environment in Wellington. Our focus when we go into camp next Monday is to bring the new guys up to speed with our structures and the team culture.
"There is also a lot of experience in the squad. DJ Forbes will play his 82nd World Series Tournament in Wellington, and a number of the other players have been part of successful campaigns over the years. It is good to have a mix of experience and new talent to keep us fresh.
"We are feeling confident heading into the Wellington tournament. There were big improvements in the team between the Dubai and Cape Town tournaments as the squad got to spend more time together. Since then we have had the Nationals and a four-day camp together in Rotorua, so we enter the build-up this week match-fit and gelling as a group.
"Wellington is always the highlight of the series for the boys. There is nothing like having a big crowd at Westpac Stadium cheering the team on. It’s also special to be able to play in front of our family and friends.
"We enter the tournament defending champions and we will be giving it our all to hold onto the Wellington trophy and make it four wins in a row,"
