But according to Laidlaw, the young prospect is unfazed.
"I know there's been a bit going on in the background but my job is to coach rugby; his is to play and other people can sort out the behind the scenes stuff," Laidlaw said.
"He's trained really well. In his first start he topped metres which was unbelievable. He's an athlete who makes repeat efforts which is what we're looking for so we expect him to get more game time this weekend and play really well.
"He gets his opportunity and I think he's going to take it.
"Our conversations have been about the game. We've reviewed his game and prepared him well to play this week. We're really excited around how he is going. It's another great opportunity for him to strip. He's learnt a lot from the weekend. It was his first proper sevens tournament."
Nanai-Seturo will line up alongside fellow 18-year-old Caleb Clarke, the Auckland and Blues wing, and son of All Blacks midfielder Eroni, noted for his silky skill and pace.
Clarke and Joe Webber replace Andrew Knewstubb, ruled out with concussion, and Kurt Baker, who moves to 13th man.
Laidlaw is looking to expose these emerging talents ahead of finalising his Commonwealth Games squad.
New Zealand come off a disappointing fifth place finish in Sydney. Capturing the title in the Cape Town event and losing the final in Dubai earlier in this series suggests this team should regroup and challenge for the inaugural Hamilton crown.
Emerging from a tough pool which features France, Scotland and Argentina will provide early tests on day one.
"Our game is settling down now and we understand what works for us. Sometimes we fall back into bad habits; the game against Australia we made a few bad decisions and let them get momentum in the game.
"That is frustrating but the way we bounced back showed there was a real hunger in the team to play well. We want to win a World Series so every point you play for is crucial.
"As a player and coach you always want to play at home. We are loving being here in Hamilton, it feels familiar, the guys have been able to spend some time with family. Come Saturday, the crowd will lift us and give us an advantage and we're going to embrace it."
Laidlaw also threw his support behind the push to include the women's team at the Hamilton event next year.
Sydney set the standard last weekend with the first three-day fully integrated tournament. There are now discussions around staging a four-team women's invitational event in Hamilton next year.
"We've got an obligation to grow women's and men's rugby so I'm sure people behind the scenes are looking at solutions for that. It's great to be able to watch and support the women's and men's at the same time. I'd love to see them in New Zealand for sure."
