It was the first time their New Zealand Super Rugby Aupiki champions faced the Super Rugby W champions of Australia, and it’s hoped the match will be the start of a full transtasman women’s competition.

Blues captain Maia Roos was stoked to win the inaugural battle against Australian opposition.

“I’m so proud,” she said on Sky Sport. “It was cool to play our Tasman sisters.

“It’s a big step towards growing the game. We are happy to be here and get the win.

“I don’t think the score reflects how tough the game was.”

Black Ferns captain Ruahei Demant did an excellent job steering the Blues around the field, while two stunning solo tries to teenage fullback Braxton Sorensen-McGee stole the show.

Both sides made errors in the opening exchanges, but it was the Blues who struck first through a great run from Sorensen-McGee, who beat three defenders to cross.

Patience eventually paid off as Elizabith Moimoi crashed over for the Blues’ second.

A long-range effort from Sorensen-McGee saw the Blues add a third and take a 19-0 lead at the break.

The Blues continued to search for opportunities, and it took a strong carry from Portia Woodman-Wickliffe for the hosts to claim their fourth.

A late try from Cheyenne Tuli-Fale put the icing on the cake for the Blues, but the Waratahs did cross for a late consolation through Desiree Miller, from a stunning chip to the corner.

But the Blues had the last say, by winning a turnover at a scrum and Krysten Cottrell scoring in the corner.

Despite the loss, Waratahs captain Emily Chancellor was upbeat about the outcome.

“What a huge opportunity for Australia and New Zealand,” she said. “Well done to the Blues, they were exceptional.

“We haven’t had much practice in those conditions, but it was fun.”

Up next for women’s rugby is the Pacific Four Series next month with matches against the Wallaroos, Canada and USA, starting on May 10.
