Speaking to the Herald, Ms Black said she was present during the October 15, 2007, raids when a kohanga van was pulled over and searched.
The stain of the day hadn't left her. "It's our iwi name being dragged in the mud. It's not just about Tame Iti, it's about Tuhoe."
Her own family would be giving a koha to Iti, who was a past chairman of a kohanga and a strong supporter of the movement.
But she wanted to make it clear there would be no dipping into institution funds, and kohanga outside the tribe's region had not been asked.
One kohanga representative who didn't want to be named said families from her institution were happy to be asked for support but the association with firearms and children didn't sit well. "If he was fighting for the kohanga reo then yes, but he's fighting to save his own backside."
Iti's lawyer, Russell Fairbrother, said he was unaware of the email. He would not say what Iti's bill was running at but said regardless of the cost he would be representing his client for the "long haul".
