The 19-year old is continuing to make an impression on the ATP tour. He reached a high of worldNo23 in June, the youngest player to be ranked in the top 25 since Richard Gasquet in 2005.
Shapovalov was named the 2017 ATP Star of Tomorrow, and was the youngest player to finish in the top 100 after a season in which he beat world No1 Rafael Nadal and Juan Martin del Potro to reach the semifinal of the Montreal Masters.
He also became the youngest semifinalist at an ATP Masters 1000 event during the year.
''It's is a great tournament and I'm looking forward to being back,'' Shapovalov said.
''The fans were incredible last year and it's so much fun - I can't wait to get back on to centre court.
''Auckland is awesome. I jumped off the Sky Tower when I was there last time. I'm not sure what I'll do on this visit but I'm sure I'll find something fun.''
ASB Classic tournament director Karl Budge was thrilled Shapovalov would be back.
''There is no question he is a star of the future, and he's delivering some big matches right now. He's so athletic and dynamic, just so exciting to watch on court.
''The ASB Classic has a reputation for showcasing the next generation of talent: Nadal, Federer, Wozniacki and Murray have all played here early in their careers. . . We're certain that Shapovalov is going to be another name to add to this list.''
