Police attended two large disturbances involving boy racers overnight - but took no action apart from speaking to those involved.
The first, in an industrial area along Rosebank Rd in the Auckland suburb of Avondale, was reported just after midnight.
"Police were called to this incident about 12.30am on Saunders Place and spoke with those involved, but there were no arrests or anything of that nature," a spokeswoman said.
The second occurred on Crawford St in Avalon, Hamilton. Police were called around 2.30am to a report of disorder between groups, she said.
