A man who stabbed one of the country's most notorious murderers more than 40 times has been sentenced to preventive detention.
Siuaki Lisiati, himself a convicted killer, stabbed double murderer Graeme Burton with two shanks while the men were in the maximum security prison at Paremoremo in Auckland in May 2018.
Flanked by four security staff in the High Court in Auckland this morning, Lisiati was sentenced by Justice Venning to preventive detention, to serve a minimum of five years and two months.
He was already serving a sentence of life imprisonment for murder.
Lisiati swore at the judge after being sentenced.
