Domestic violence charity White Ribbon has threatened to withdraw its support from an anti-violence event after Destiny Church leader Brian Tamaki was booked to speak.

We Stand Because We Care was supposedly a community event, but White Ribbon campaign manager Rob McCann says it appears to have been "taken over" by Destiny Church group Man Up New Zealand.

"We thought it was organised by the community," Mr McCann told Newshub. "They're using the White Ribbon name for purposes we don't approve of."

White Ribbon says Mr Tamaki's "homophobic remarks" and the church's messages don't fit in with White Ribbon's kaupapa.

"I am writing to say that we are extremely concerned about the We Stand Because We Care Event and the association with White Ribbon," reads a letter he sent to Man Up, and supplied to Newshub.

"As you are aware, White Ribbon has only been informed of the details in the last few days, and this has given us very little time to ensure that the event fits the kaupapa of White Ribbon."
