NATABUA High School won the West Zone Two Secondary Schools Rugby Union 7s under-19 grade after beating surprise finalist Yasawa High School 12-7 in the final.
The Natabua boys were pushed to the wire by their Yasawa counterparts and scored in the last minute to gain victory.

"Yasawa was very impressive but lost concentration in the last minute to allow Natabua to score the winning try," Danford said.
"They will be the team to watch this year. They have a lot of raw talents. We are glad that they travelled all the way to be part of our tournament."
