The billboards of Maori Party co-leader Debbie Ngarewa-Packer were defaced over the weekend, with some spray painting over her moko kauae.
In a post on her Facebook page, photos show four of her billboards were targeted - with three in particular having white paint sprayed over moko kauae.
A fourth one had a crude word written across it.
In her post, Ngarewa-Packer said racism wasn't about how looked, "it's about how people assign meaning to how you look".
"Whakapapa is our strength, as is replacing hate with love. I'm so grateful to all our whānau out there eradicating racism and promoting #believeinMaori."
