Henry (17) won gold in the youth 69kg welterweight category at the national championships.
It was a convincing victory in the final for Henry, who beat Aucklander Eruera Mahara
5-0.
His achievement was recognised with selection in next month's tri-series competition in Auckland.
Fighters from Australia, Samoa and New Zealand will participate.
It will be a big ask for Henry but he has shown good skills this year and is starting to build an impressive record.
The win at the weekend was just a continuation of a year during which he has notched some good victories.
He has won all eight of the bouts in which he has competed, including the South Island golden gloves title.
He was also awarded the most scientific youth boxer award.
Long-term, Henry is hoping to go on and compete at the youth world championships next year.
At the same championship, Kasib Murdoch, also from Dunedin, made the final of the youth 64kg light welterweight category.
Despite a great performance, Murdoch was second after a 3-2 split decision 3-2 went the way of opponent Xavier Mataafa-Ikinofo, from the central North Island.
