Four people have been arrested over an assault in Auckland earlier this year that left a man blind in one eye.
Police say a second victim suffered serious head injuries in the assault at a bar in Browns Bay on the North Shore on 3 May.
Two men were arrested on 9 June and two more have been arrested on Wednesday.
Two face charges of intending to cause grievous bodily harm, while the others face assault charges.
Police say they are not looking for anyone else in relation to the assault.
