Ms Lewis told the Herald that she did not intend to enter a plea on Friday, and will seek further legal advice.
She has lodged a complaint with the Independent Police Conduct Authority against the investigating police officer.
"My faith in the justice system is weakening," Ms Lewis said in her complaint.
"I am a victim, not the assaulter. I have suffered enough trauma and suffering through this ordeal, and now [the police officer] is saying I am up for assault?"
Her partner, Drew Cocker, had blamed members of his family who disapproved of their relationship for the attack.
Mr Cocker claimed his aunt threw the first punch at Ms Lewis, who struck back at a barbecue that was meant to be their house-warming party.
Ms Lewis, who still has to wear a neck brace, said she was also seeking help from the Hamilton Abuse Intervention Project.
She has been auctioning her underwear online to raise funds to pay for her legal and dental costs.
