Ella Eketone in 2013 after she was pushed by police and landed on the concrete, smashing two front teeth out of her mouth and causing other facial injuries.

An Auckland teenager has reached a confidential settlement with police, three years after an officer pushed her to the ground, knocking out her teeth.

Ella Eketone was 15-years-old at the time of the incident in 2013 when police used "excessive force" to break up an out of control party.

She was pushed to the ground by a police officer with such force that it knocked out two of her front teeth and caused other facial injuries.

Eketone's lawyer, John Munro confirmed on Tuesday that a "confidential settlement" had been reached with the police.

He could not comment further.

It was settled sometime this month, he said, and was between the police and the family. They would not be pursuing further legal action.

The Independent Police Conduct Authority (IPCA) last year ruled that the officers breaking up the party used unjustified and excessive force, and the young girl was not posing any risk.

However the internal investigation by the Counties Manukau Police in 2013 found the officer had used "reasonable force" and acted appropriately given the circumstances.

Munro said the IPCA findings did not influence the settlement.

"The IPCA, they just make decisions but they don't make recommendations or bind anyone," he said.

At the 2013 party, around 200 young people who police said were intoxicated, had spilled on to Wellington St in Howick and several fights broke out.

Bottles were also thrown at officers as they tried to disperse the crowd, police said.

Eketone claimed she was pushed numerous times by an officer as she was leaving the out-of-control party because she was scared.

She eventually fell on to the ground face-first, knocking out her two front teeth and other injuries to her mouth and nose.

She spent the night in Middlemore Hospital.
