The 17-year-old Otago boxer defeated highly ranked North Island competitor Ali Ismalluh at the Canterbury Championships over the weekend to win the male youth 69kg category.
He clocked a unanimous decision with a busy effort in all three rounds. It was Henry's 49th amateur bout and an important win as he builds towards the youth and junior world boxing championships next year.
Henry is from a family of boxers. His father Ryan and mother Cherine are both former South Island Golden Glove winners.
His sister Zsana also fought at the Canterbury Championships but was stopped in the second round by Deb Bean in the women's elite novice 75kg division.
Dunedin's Jaime Heperi was defeated by Zoe Cummins in the women's elite novice 57kg division.
