"I have been taught to stand my ground and not let anyone push me around," added Muzariri, 17.
"When I go into a male-dominated society it's just really empowering to be able to freely express that [through poetry]."
Muzariri said it was her teacher who first suggested she give spoken word a go.
"My teacher said 'you have a big mouth ... I think this would be good for you'."
The team need to raise $2400 dollars in the next 10 days to get them across the Ditch and performing against Australia's best.
The group was excited but a little nervous about heading to Sydney to represent New Zealand on October 23.
"Every time someone says 'you're representing New Zealand' I freak out," said Rico.
All four young poets were in their first year of performing spoken word and this was Marist's first year with a team entered in WTFL.
Despite being new to the medium, Crerar, 18, said spoken word was a way to "speak things that have been on my heart for a long time".
Responses she got after performing her first poem, which dealt with social stigma around mental illness, made Crerar realise "wow, this is really meaningful."
Rockwell, 18, agreed, saying poetry gave her an outlet to speak on issues she was passionate about.
"I feel like it's my responsibility as a young woman to speak up against injustices."
The Auckland Poets Collective, which helps run WTFL, collaborated with the Sydney-based Bankstown Poetry Slam to make the transtasman battle happen for the first time.
