Police arrested several people for their own safety because they were too drunk, during yesterday's Raggamuffin Festival in Rotorua.
While officers said they were generally "happy" with the behaviour of the 14,000 revellers at the festival, there were still 10 arrests in and around the stadium.
Most were alcohol related, including some people who were disorderly or needed "to be taken into custody for their own wellbeing due to extreme intoxication".
"It is a concern that some people seem to use these events as a chance to push the boundaries, and we will continue to give thought to how we can better achieve compliance," Rotorua area commander Inspector Bruce Horne said.
Five people were also arrested at Friday night's Raggamuffin pre-party.
