Patterson was the 2014 Commonwealth Games gold medallist in the Men's 85kg division.
At a recent competition in Papatoetoe, which was Kumeroa's last prep-weight before departing, he exceeded his own personal bests with a 125kg lift in the snatch and 151kg in the clean & jerk.
Chris Kumeroa said his son has broken 33 national records in those two disciplines over the last couple of years.
"Despite living in Auckland, our people in Whanganui have been extremely supportive towards him going to the worlds and we are extremely grateful.
"He is of Whanganui Iwi decent and we try and keep him connected to home as much as possible, so he will always know where home is.
"This is particularly important as we forge forward as an Iwi, as like us all he will have a role to play in providing support for our collective effort as a people."
The IWF Youth World Championships start tomorrow, NZ time, and run to April 10-11.
