Pua Magasiva's love for acting was inspired by his older brother, Robbie Magasiva, a well-known actor in New Zealand. His brother's support coupled with a determined spirit to succeed as an entertainer has helped the Samoa-born actor land roles in several feature films including New Zealand's "Crime Story" and "Aidiko Insane" and the domestic independent feature "Eye of the Storm".
Magasiva was also in several international television projects including the UK's "Revelations - Unfinished Business", a Maori television drama entitled "Aroha - Haka & Siva", and a guest role on New Zealand's hit soap opera "Shortland Street".
Magasiva attended St. Patrick's College in Wellington, where he was known for his natural entertainment ability. In addition to acting, he is a talented dancer, singer and athlete.
