Rotorua police are asking the city's adults to take care of their children, especially around alcohol, after about 100 teenagers spilled out onto the street during a party on Saturday night.
Senior Sergeant Denton Grimes said police were called about midnight after a party near Old Taupo Rd got out of control.
Mr Grimes said police attended a "disorder incident" involving up to 100 people. Five were arrested for disorder type offences.
"There were injuries to some of those involved, but they were not believed to be serious."
"Police were required to disperse the group and moved them away from the area and moved them down Old Taupo Rd to split them up."
