Less than 48 hours into their holiday, two American tourists were the victims of a "vicious and unprovoked" attack in Northland - and one will need reconstructive surgery.
Sergeant Phil Le Comte said police were investigating the incident outside the Bay Adventurer Backpackers on Kings Rd in Paihia about 3am on Saturday.
"A vicious and unprovoked attack on two male American tourists, aged 22 and 23 years respectively, resulted in both being hospitalised overnight for their injuries."
While the pair were discharged from the Bay of Islands Hospital later, the 22-year-old will undergo reconstructive surgery at Middlemore Hospital in South Auckland in the next few days, Mr Le Comte said.
He said a weapon was not believed to be involved.
