Michael Murray is expected to be kept out of general population as he serves his time for killing Connor Morris.
He was found guilty of murder yesterday by a jury in the High Court at Auckland.
As he was led from the court room, a family member of Connor Morris, who had Head Hunters connections, yelled, "Murray your day's coming".
Criminologist Greg Newbold said Murray would likely be kept in protection and his location secret.
"He'll have to have a fairly close eye kept on him for most of his sentence," he said.
