Five people have now been arrested over the the assault which left a North Shore kebab shop owner in a coma.
Bryan Johnson, 40, was left in a coma following the beating at the All Go Kebab in Glenfield, on Auckland’s North Shore, on August 28.
Surgeons took 15 hours to reconstruct his face but it will still never be the same again, while the extent of his brain injuries are still to be determined.
His injuries included broken eye sockets, a fractured forehead and jaw, brain injuries and a shattered nose.
Four men, aged between 19 and 28 years old, have been charged over the incident.
Three of the men were charged in relation to the assault itself and the fourth with subsequent discussion about it.
They appeared in the North Shore District Court and were remanded in custody.
Earlier, a 27-year-old woman was arrested over the assault.
Detective Sergeant Adam Lough said the attack was premeditated and Johnson knew some of the accused.
He told TV3 news it was a “who-dunnit” case which had required some “old-fashioned police work”.
