Last week an elderly man blocked her into a mobility park she was using at Westfield Glenfield, yelled at her and threatened her with his walking stick.
"He parked his car behind my car and jumped out like he was ... in his 20s with his walking stick and came up and said, 'You need to move your car because you're not disabled'.
"I said that I wasn't but my son was, and he looked at my son and said, 'What? This boy? He's not disabled'. He got his stick and waved it around at me and shouted at me and I just stood there and said, 'I am sorry but I won't be moving, I am entitled to park here just like you are'. And he threatened to call the police so I pulled my phone out and offered to do it for him because he was the one waving a stick in my face."
Her son is permanently brain damaged and as he gets older is harder to transport, she said.
"He had a brain tumour which he had removed, but in the process lost half of his brain so it's caused a lot of problems ... he's very much like a small baby.
"He's not light, he's getting heavy."
The problem was common with people she knew who also had disabled children, she said.
"It happens all the time, it's a big issue.
"I would hate to think how many people it happens to every single day because it is not a nice thing to happen."
Another Aucklander, Bonnie Robinson, suffers from multiple sclerosis and said she was often questioned about her use of the parks despite displaying her permit.
"I have had people come up to me," she said. "They have just queried and I can understand why as long as people are polite, respectful and sensitive about how they do it.
"Not everyone who parks in a disabled car park actually wants to tell people why they can because it can be quite private."
CCS Disability Action chief executive David Matthews said the issue arose quite often, and people needed to be reminded to tread carefully before accusing anyone of misusing the parks.
"Some people's disabilities are not obvious and, secondly, that person might be the legitimate driver for the disabled person and that is a legitimate use."
