Several of those charged after rioting during the Undie 500 weekend in Dunedin last month, including a high school pupil, have admitted their offending.
Some of the 61 people charged after two nights of partying on Castle Street dissolved into mass disorder appeared in Dunedin District Court on Thursday.
High school student Dillon Matt Todd, 18, was caught as he was about to launch a glass bottle at the police during the unrest in September.
In court on Thursday he admitted possessing an offensive weapon with intent to cause violence. He is seeking a discharge without conviction and will appear again later this month.
Michael Hamish Allen, 18, was convicted of disorderly behaviour, forestry worker Joshua William Cox, 17, of obstructing police, Joshua Russell Cochrane, 19, of breaching the liquor ban and Ryan James Reid 19, of disorderly behaviour likely to incite violence. All were fined.
