Rugby: Maiakawanakaulani Roos' heartwarming reaction to being named youngest Black Ferns captain

Maiakawanakaulani Roos is as surprised as anyone, after being named Black Ferns captain for their final Pacific Four match against the USA on Saturday.

Roos, 21, will become the youngest-ever skipper to lead the NZ women, breaking the record previously held by Dame Farah Palmer by three years.

As the team was announced, her shock was evident, quickly turning to delight, as her  teammates congratulated her on the historic achievement.

Roos then video-called with mother Maia, her grin saying it all, as she delivered the news she was named captain.

Coach Allan Bunting has praised Roos' leadership throughout their Pacific Four campaign, as the world champions look to wrap up the title with their third straight win. 

"Throughout my time in the Black Ferns, Maia has been exceptional - a true professional both on and off the field - and her presence is widely felt," he said. "A key member of our leadership group now, her daily habits and actions transition into consistent performance. 

"She is a good human and is always looking out to help others. We have great confidence in her captaining the Black Ferns on Friday."
