Judge Harvey convicted and discharged him on the two charges he was found guilty of before directing the transcripts be sent to police District Commander for Northland, Superintendent Russell Le Prou, and recommended that he forward them to the IPCA.
The police officer at the centre of attention during trial was Hikurangi-based Constable Cameron Stack who was accused by Rota of calling him a "n****r" and "black c**t".
Mr Stack denied the allegation.
In his evidence, he said Rota was verbally abusive, aggressive and made obscene gestures when he got out of a parked ute outside Hikurangi Primary School on November 11, 2015.
Rota's evidence was there was no need for the officer to hassle him outside the school because he had not broken the law.
He claimed a week earlier, Mr Stack stopped him riding a motorbike on Valley Rd in Hikurangi and racially abused him.
Mr Stack denied the allegation.
Rota said yesterday he was glad to be back home and away from the justice system.
"I prepared for the worst but the verdict and the judge's conduct of the trial has restored my faith in the (criminal justice) system.
"It was a traumatising situation to be in but to see my family hurt was not easy. I couldn't be more happier," Rota said.
Judge Harvey's recommendation, he said, was a "bonus" for him as he didn't expect that coming.
He hoped the New Zealand police and the authority investigated the alleged actions of the officers involved in his arrest as well as Mr Stack allegedly racially abusing him.
Mr Le Prou yesterday said he noted the jury verdict and would wait for correspondence from the judge.
The correspondence, he said, would be assessed before any possible course of action was decided upon.
Four days after Rota was arrested, his partner Kathleen Connell filed a complaint of alleged racial abuse by Mr Stack to the authority.
