The man involved in an altercation with a 15-year-old has been taken to Waikato Hospital for surgery to reattach some of his ear.
The 23-year-old was taken to Tauranga Hospital last night following a fight at a Links Ave home about 7pm.
Detective Sergeant Darryl Brazier said most of the man's ear had been cut off.
"It was quite a nasty laceration . . . this guy, having his severed but not completely off."
The man was transferred to Waikato Hospital today.
Police apprehended a 15-year-old who will appear before Tauranga Youth Court next week.
Mr Brazier said police recovered a weapon they believed was used to inflict the damage, but would not release more information on this as the matter was now being dealt with through the justice system.
