Campers had been allowed to bring unlimited alcohol in. The festival had been granted a special licence but festival organisers reverted to BYO status after pressure from festival-goers who had already purchased tickets.
I'm horrified to read some comments on social media hoping it doesn't get shut down next year by the "fun police".
I'm sure those innocently trying to celebrate New Year but who ended up sheltering under mattresses in terror would not describe the evening as fun.
Neither would police and emergency service staff, who work tirelessly on public holidays, not able to spend it with their own families, so they can keep communities safe.
I wouldn't have minded if police had just blasted the mob with tear gas and let them wake up on New Year's Day in a cell.
If we needed more proof that BYO should not be allowed at public events, here it is.
People who moan about "police state" and "fun police" should remember it is the police who protect us from idiots like the Gisborne rioters.
We should be grateful for the police and regulations which made our Mount New Year fun but without trouble.
