Senior Sergeant Craig Dinnissen said a car involved in a hit-and-run incident on Saturday had been involved in other incidents over the course of three hours in Dunedin, causing "a huge amount of carnage and calls for service".
The 44-year-old man ran red lights, abused people, and intentionally drove over a child’s bike at the Dunedin Botanic Garden, after the child jumped from the bike to avoid being run over.
The man then hit another car head-on in South Rd before fleeing.
The alleged errant driver was found at his home at 7pm, and was charged with dangerous driving causing injury and drink-driving.
Another motorist was stopped in Cumberland St at 5.06pm on Saturday after being seen driving erratically on State Highway 1.
The 48-year-old man said he had just come to Dunedin from Central Otago and was "just driving around", Snr Sgt Dinnissen said.
He was told to return home, and a breach notice was submitted.
On Friday, a 64-year-old woman left her Middleton Rd home and went to Wakari Hospital to visit a friend.
She was found and taken home by police, but shortly afterwards she left home again, this time going to visit a friend at Dunedin Hospital.
She was warned for breaching lockdown rules.
She was trespassed from the store.
Police also dealt with several reports of people partying over the weekend, in breach of lockdown rules.
They were called to Wairoa St at 9am on Saturday after reports of a loud party the night before, where multiple bubble breaches were alleged to have occurred.
At 10.50pm on Sunday, police were called to Clermiston Ave after reports of a party.
A man at the address had bail conditions to reside in Roxburgh and not to consume alcohol.
Earlier on Sunday, at 4pm, six men were found partying in Corunna St. Five of the six lived elsewhere.
On Sunday morning, police received reports of people whitebaiting at Henley. No-one was located.
Snr Sgt Dinnissen said police generally were happy with the behaviour of Otago residents, but a minority were causing work for police due to their "ignorant antisocial behaviours".
