The Maori Party's Te Tai Tokerau candidate says he is being unfairly targeted because of his religious faith.
Reverend Te Hira Paenga says some of his hoardings have been chopped down.
A complaint has also been laid with the Advertising Standards Authority, because of his religion.
Mr Paenga says the complaint said his hoardings were objectionable because he appeared in "a priest's costume".
Mr Paenga said he does not just dress up as a priest, he is a consecrated deacon in the Anglican church.
He said although he realised there is a separation of church and state, that did not mean that people with a religious background were not allowed to stand for Parliament.
The authority ruled there were no grounds for the complaint to proceed.
