Candy Edmonds was subjected to a vile racist rant during a road rage incident in Perth this week.

A New Zealand woman subjected to a shocking racial tirade during a road rage attack in Perth says she has been racially abused the whole time she has lived in Australia.

Candy Edmonds, 28, originally from Kawakawa in Northland, said Kiwis were second class citizens in Australia "if we're lucky" and she just "went numb" when the courier driver launched his tirade.

"I'm so used to it in Australia."

SUPPLIED Perth-based Kiwi Candy Edmonds with dog Kihi. She was racially abused during a road rage incident.

The driver chased her in his truck and rammed into the back of her Holden Astra after she gave him the finger when he objected to her passing manouevre.

When he caught up to her, he approached her car and stuck his head through the window before he began an extraordinary rant which she captured on her phone.

Edmonds, who has a make-up business, uploaded the footage to the internet where it has been viewed thousands of times.

At one point the TNT driver asked: "What f...ing land are you from?" and then asks if she is "f...ing Arab or something" or a "f...ing Muslim c..."

Edmonds swore back at him.

TNT said it was investigating the incident, which happened during afternoon rush-hour on Thursday.

Edmonds moved to Perth six years ago, following her parents, who have since moved back to New Zealand. She has a Maori, Croatian, Austrian and Irish background.

Ugly racism raised its head on her very first night out in Perth, she said, when her brother was attacked by a man who called them "black c...s".

She said she had also suffered ongoing abuse during jobs in the hospitality industry.

"I broke down in a bar one time, I cried, it's serious, it hurts talking about it."

She said she was constantly harassed about her accent, told she didn't speak properly and told to "go back where you came from".

"A lot of Aussies don't like New Zealanders, I don't know why. Even Aboriginals don't like us here."

Edmonds fought tears as she described the "scary" road rage incident.

"We'd gone through some lights, we were coming into a merging lane, I was on the inner lane, because it was a truck I just zoomed straight past, I'm scared of trucks."

Edmonds said the driver started beeping his horn and she gave him the finger. He "charged towards me" and she was forced to speed up.

"He rammed me and shoved me forward, I had my brakes on. I jumped out of the car and took a photo of his number plate and signalled I was calling the cops."

She drove off but the man caught up again and this time approached her car. After his rant he hit her windscreen with his arm.

Edmonds received support on Facebook but has also copped a lot of flak. One man wrote that he saw the whole thing. "You pulled out on him and you're lucky to be alive. Then you abused him and gave him the finger and drove off. That's disgusting form."

She said she would not go to police, as she didn't like them, but wasn't going to let the incident put her off Australia.

"I know there are decent people out there. I can't let the one ruin the many. It's made me want to get my mum over here to help me out."
