Current and former MPs and "ordinary people" banded together to pay the $632 fine Hone Harawira received last year for defying police at a 2012 Auckland housing protest.
But while one of his Mana Party contenders claims Winston Peters was among the donors, Mr Harawira will not name them, even though it appears he is required to do so under parliamentary rules.
The Mana Party leader was arrested when he joined protesters fighting the removal of state houses in the East Auckland suburb of Glen Innes. He was alleged to have locked himself in his car and turned his music up, blocking a Housing New Zealand-contracted truck from leaving with one of the homes.
Several months later he was found guilty of failing to comply with a police instruction, fined $500 and ordered to pay $132 court costs.
But last week at a public meeting of Housing NZ tenants in Grey Lynn, the sole nominee for Mana Party candidate for Tamaki Makaurau, Kereama Pene, said: "Our Mana leader was dragged out of his car in GI. He got done for it. Do you know who paid his $500 fine?"
