On Saturday morning, WGHS overcame Tauranga Girls' College 4-1 before beating Westlake Girls' High School 5-nil in the semifinals to advance to the final against Havelock North High School on Sunday.
WGHS went two games up against their Hawke's Bay foes with Traill and Brown winning the tie's two first games. Despite WGHS No 1 Ferguson losing a tough match, Year 13 Collins won her game in four sets to secure the national title and make team captain Saunders' game result irrelevant.
"I feel like it really hasn't sunk in," Saunders said.
"Everyone is like 'wow you're national champions' and it's pretty surreal but awesome for the hard work to pay off and I'm really proud of the girls."
Saunders, a Year 13 who had attended the competition for five straight years and captain for three, said it was satisfying to get the win after four years which featured two second-place finishes, a fifth and a sixth.
"It was pretty awesome because we came second in the first two years and it was really cool to see all the girls improve and it's great to finish off with a win."
WGHS were favourites going into the tournament with an even spread of B grade players which gave them the No 1 seeding.
Saunders said while she was confident in her team's ability, she was never sure of the win especially against Havelock North High School as the second seed.
"It was obviously very exciting and we knew we had a really good chance, but you still really never know because you have a lot of players who are under-graded and it was still really unpredictable," she said.
"It was even more nervous having that top seed because we knew that we were almost supposed to win but Havelock were pretty close to us, it was a close final."
Saunders praised the involvement of the team's younger players and was hopeful, if not a little wistful, for the future of WGHS at the tournament.
"It's really exciting for the next few years as well because there are two Year 11s and three Year 9s so they are all just going to get stronger.
"I'm very jealous because I love the tournament and I have a feeling they'll get close to it again."
