Similar play soon resulted in Titietasi scoring again between the posts, followed by another successful conversion, taking Sacred Heart into the halftime break with a 14-10 lead.
Early in the second half Dhanya King scored in the corner to boost Sacred Heart's buffer to 19-10. However, Girls' High fought back into the match with two good tries to gain the lead 20-19.
Sacred Heart weren't done though, and on the back of strong ball running, excellent support and gritty determination, Dhanya King scored again in the corner to close out the victory.
"It was an incredibly high-quality game played by two talented teams," McAlley said.
"I'm immensely proud of our team and the hard work they've put in over the past 18 months to improve as much as they have.
"I've seen them ignite their passion for the game and really come together and work well as a team."
McAlley said he, coach Ian Hauraki, manager Jude Trumm and the team had focused on getting the foundations of the game right before targeting wins.
"For us it's very much been about progress, not perfection. And that's paid off. A win of this scale in a game against a side as formidable as Hamilton Girls' High is outstanding."
The team would have gone on to play the country's top four girls' teams as representatives of the Chiefs rugby region, however, given the impacts of Covid-19 that won't happen this year.
Wayne Maxwell, who is the head of game development for female rugby in the Waikato Rugby Union's high-performance team, presented the cup to the team.
