She says other men on bikes surrounded her car and blocked her in, while another car pulled in front of her to stop her from escaping.
"They were banging my windows, swearing at me, calling me a f***ing bitch, telling me to go f*** myself, kicking my car...I was absolutely terrified, and I was really pissed off too."
She says she had no idea at the time that she had interrupted a tangi, as she had not seen the casket that was reportedly at the front of the procession.
"When I heard it was a funeral procession I was like okay, fair enough but that reaction is not justifiable in any way.... he could have knocked on my window and said it's a tangi, and I would have been like 'okay sweet' and pulled over."
She says the situation did not have to go down how it did at all, and while she is upset she's also confused.
"I'm left feeling so confused as to how they expect us to respect funeral processions and tangis if they're not clear about it. I'm not going to treat every bike procession like a funeral because they're not all funerals.
"They have every right to bury their dead and I respect the tangi but they don't have the right to harass me for accidentally stumbling on it."
A police spokesperson told the Herald they were investigating a report of intimidation.
"A motorist reported that they had been harassed by motorcyclists while driving on Cambridge Terrace, between Buckle Street and Courtenay Place, at around 4pm."
They said anyone who witnessed the incident should contact them via the 105 phone number or online, using My Report.
"Please reference file number 220808/0104."
