A Tongan woman has opened up about the toll of racist abuse she has suffered since moving to New Zealand.

In 2014, Maryanne Tupou moved to Christchurch, and has since been on the other end of diminishing remarks made by people in public.

"One night, we were just in some club and on the dance floor... and there was a guy standing there and he just looked at me and was like 'n****r bitch'!" she told Radio New Zealand.

She also spoke of an instance where she had been abused on the streets.

"They just drove past, put their head out the window and they're like 'get back to your f**king boat'!" she told RNZ.

"And I've had so many people that go, 'oh you're pretty hot for a black girl' or 'oh I've never f**ked a black girl before'."

She believes more education about different cultures is needed in New Zealand.

Tupou's story follows a Newshub story last week about Mia Griffiths, who opened up about being racially abused at her waitressing job in Auckland.

Mia said being on the receiving end of racist comments is a uniquely painful experience.

"It's like you're ashamed to be you," she told The Project last Tuesday. "You're ashamed to know your culture, to know your race. To wear your skin, despite the colour. You just feel absolutely defeated, and I hope nobody experiences anything like it."
