Police say they are "comfortable" with the actions of officers who attended a Hamilton party early on Sunday, after a teenager claimed she was assaulted while being arrested.

Police said they were aware of a Facebook posting alleging a 16-year-old female was assaulted, although no formal complaints had been made.

There were multiple calls in the early hours of Sunday from north Hamilton residents reporting that about 50 teenagers were fighting in the street.

The first police officers at the scene had bottles thrown at their vehicle from the crowd.

"The teenagers involved had spilled out onto the road from a nearby party which had got out of control and was subsequently closed by police resulting in six arrests," the statement said.

"A senior police officer was present at the incident and witnessed the arrests that took place. Based on current information, police are comfortable with the arrest procedures and actions carried out by their staff."

The allegations follow claims of heavy-handedness by officers who attended a party in Auckland last month.

Investigations were launched after pictures of a bloodied Ella Ekatone, 15, were posted on Facebook by friends who attended an 18th birthday party in Howick.
