Wanganui Lightning won convincingly, 15 goals to Taranaki's 2.
Wanganui also entered a second under-14s team, the Wanganui Raptors, who finished fourth.
"We are extremely proud of their tenacity throughout the tournament, never giving up and playing hard right to the final whistle. This was the first national tournament these children have played in, not to mention the majority of the team only started playing rink hockey this year.
"We as a club certainly look forward to watching these young players develop further over the coming year and we certainly look forward to seeing what the 2021 nationals will bring.
"It is great to see the potential future of Wanganui rink hockey, with the children doing so well at such a young age.
"For anyone interested in learning the game of rink hockey, you don't need to know how to skate as we will teach you," Ross said.
