Green co-leader Marama Davidson tells people to 'delete' themselves in late-night Twitter tirade

Green co-leader Marama Davidson has called on the "bros" to "delete" themselves in a Twitter rant criticising the treatment of ethnic communities in New Zealand.

In a late-night tirade, Ms Davidson said ethnic communities had been treated like "economic units" long before the release of secret phone recordings by former National MP Jami-Lee Ross highlighted an alleged cash-for-candidate system.

On the audio, Mr Ross and National Party leader Simon Bridges discuss the value of Asian members of Parliament, including the potential candidacy of two Chinese individuals after an alleged large donation from businessman Zhang Yikun.

In her tweets, Ms Davidson said "white immigrants" had never been "slayed" by the same derogatory or dehumanising abuse as Asian citizens or people of colour.

"Under this long-standing false narrative, struggling and marginalised communities have been pit against each other," Ms Davidson wrote, saying people shouldn't be surprised by the revelations coming out of the National Party.

Admitting she was "p*ssed", Ms Davidson kept her most brutal comments for the political analysts she labelled as the "bros" that "cover up power abusers".

"Get out. Delete yourselves," she said.

She later also joked she may try to introduce a Member's Bill to ban "white-person tofu".

Her comments were met with a mixed response of praise and confusion, with some Twitter users arguing that it was unfair to criticise all white people as abusers.

"My paternal great great grandfather was a German immigrant and during WW1 he was put in an internment (concentration) camp... he was white," wrote Sam Hill.

"Thanks Marama, it's heartening to hear your voice cutting through the callousness of this situation," wrote @hetifunwin. "Just sorry, but not surprised that it's you that has to do it."

Ms Davidson is no stranger to provocative language. In August, she went on a crusade to reclaim the C-word, dropping it three times at an anti-racism rally attended by families.

Standing by her use of the word, Ms Davidson said it was a "powerful word for women and shouldn't be used as abuse".
