Mafi is slight in stature, but she can play and has plenty of pace on the wing. Her three games in the Farah Palmer Cup have yielded two tries, including an important five-pointer in the 29-25 victory over Canterbury last weekend.
"Making the team was beyond what I expected. My original goal was to get into the Auckland secondary schools team, so making the Storm was a big thing for me," Mafi says.
Fa'amausili gave her the heads-up the Storm selectors had their eye on her, so she upped the ante at training. While she plays mainly at halfback for Marist and Mangere College, she says the transition to the wing has been made easier by the Storm environment.
"The women are welcoming and supportive. Going into the team, I thought I was below all of them. They showed me that it doesn't matter what size I am," Mafi says.
Coach Dean Bickerton took her aside and was able to instil some confidence in her at the first training. She hasn't looked back.
Now she is rubbing shoulders with Olympic silver medallist Tyla Nathan-Wong. Sevens is an option for Mafi, who is keen to head to the US with the Marist sevens for a tournament early next season.
From April to August, Mafi's rugby routine is a busy one. Aside from training, she will play for Marist on a Saturday, have church and training on a Sunday, and then is co-captain in the Mangere girls' team which plays in the developmental 10s grade on Monday nights. The younger girls in the school side look up to Mafi.
"There are some very young girls in the juniors. They are still learning, but this season they showed me a lot of passion. They surprised me with how well they did."
The Storm host Otago at Colin Maiden Park on Saturday, and Mafi is sure to be in the mix.
