Police had already charged one man with murder and yesterday following raids on gang homes in Moerewa, arrested three men and a woman.
They will be appearing in the Kaikohe District Court today on a number of charges including murder, party to murder and conspiracy to pervert the course of justice.
"We have been receiving great assistance from the public who have supplied information that has been crucial in achieving today's results. The investigation team has been working tirelessly to see these people are held to account," said Detective Inspector Kevin Burke.
"I believe that many reluctant witnesses who were in fear of reprisals from gang members will now have the confidence to come forward."
