She is charged with assaulting Kellie-Jay Keen-Minshull, aka Posie Parker, in Auckland on March 25, 2023.
She faces a second charge of assaulting another person on the same day.
The charges each carry a maximum term of six months’ jail and a $4000 fine.
Rubashkyn earlier told the Herald that she had left New Zealand after receiving death threats, and did not plan to return for some time.
Parker, who calls herself a women’s rights supporter, was appearing to speak at Auckland’s Albert Park last month when she was doused in a bottle of tomato juice and had to be rushed away by security.
Her planned speech was cancelled amid scuffles and the rest of her New Zealand tour was aborted.
