"When I attempted to rebut his korero he stood and told me I've had my public parade and better find my own money to fund it."
He had also been the subject of online comments and Facebook discussion, both good and bad. "I'm surprised at the amount of negative feedback but the support has been amazing too."
Mr Spellman said businesses were embracing the idea and the abuse would not stall progression for Tauranga Te Reo - Our Te Reo Friendly City.
Mount Maunganui and Papamoa councillor Clayton Mitchell said he had received negative emails after voicing support for the project: "Some of the comments are bordering on racist and bigotry."
Tauranga resident Mary Brooks who wrote to the Bay of Plenty Times opposing the plan said residents would like the chance to discuss Maori signage before a decision was made. It was terrible Mr Spellman was being abused but called for "proper debate", she said.
"The city council are becoming like little dogs that jump whenever it's something to do with iwi and it is becoming ridiculous.
"There must be public debate on this sort of thing," she said.
Cr Gail McIntosh said she would not be backing the project labelling it a "waste of money".
