Bailey Junior Kurariki, who gained notoriety for being convicted of manslaughter when he was 12, was jailed for 14 months when he appeared in Manuakau District Court on Monday.
He was appearing on charges of assaulting his girlfriend and her cousin, assaulting a member of the public, resisting arrest and disorderly behaviour.
The charges relate to two separate incidents earlier in 2011.
During sentencing, Judge Margaret Rogers asked Kurariki if he thought he could serve his sentence in the community but he interrupted several times saying he had been targeted by the media and unfairly treated.
Judge Rogers admitted prison may only serve as a way for Kurariki to prove himself as some sort of outlaw and a way for him to strengthen and build on his notorious reputation, but she said she had no other option but to impose the 14 month sentence.
Kurariki was 12 when he was involved in the murder of pizza deliverer Michael Choy. He was convicted of manslaughter and jailed for seven years. He was released from prison in 2008.
