"I was hard-headed during those years and wouldn't listen when my parents tried hard to help me with my homework.
"So like a lot of our youth who take the wrong path because they've never really fitted in to mainstream education, I found high school became too difficult and left at 15.
"As I got older, I went off track but was slowly encouraged by my mentor Pura Tangira to much better avenues, including kapa haka."
Joining the kapa haka group Te Waka Huia in 2006 was a turning point for Ms Greening, who's lineage is Ngati Porou, Ngati Kahungunu, Te Aitanga a Mahaki, Rongowhakaata, Ngai Tamanuhuri, and Tainui waka.
"I love being Maori. I like being around my culture and interacting with people from other areas," she said.
She has been able to do this extensively through her involvement with Te Waka Huia for Te Matatini National Kapahaka, which was held in Rotorua in February as a four-day event.
Last year, Alexia moved to Hawke's Bay to study for her second degree.
