But the defiant pensioner was still refusing to apologise for attacking clamper Daniel Clout, who needed medical treatment for an open head wound and bruising.
"I'm sorry for losing my temper, that's what I'm sorry for. I've got nothing against being clamped. My objection to the whole situation was the man's manner, that's what infuriated me. He's armed with a dog and he shouts to you through a one inch gap in his window.
"Afterwards I just realised he was using me as a bait for his fight against the police."
Police have formally warned Clout he is acting unlawfully by not having a licence. He had clamped police cars and wound up many people in the region.
Trigg said the tipping point came when Clout put a second clamp on her car. "That's when I lost it."
"In no way did I bait her. I was just trying to do my job and she viciously attacked me," said Clout.
The 66-year-old, who is from Namibia but moved to New Zealand 10 years ago, did not see Clout's injuries but said her handbag and the purse inside it were tiny.
She described herself as "shaken and upset" after the attack.
"But you know what, I'm a bigger person than that. That man and his way of doing things does not define who I am as a person."
Her first-ever appearance in court was "nerve-wracking", but she was buoyed by support from the community, including those who offered to help pay her fine, Trigg said.
Clout's wife, Jess, said the attack had nothing to do with her husband's manner and Trigg had not been baited. "You can see in the video that right at the start she's going ballistic," Jess said.
