"The Rugby World Cup is a wholesome family global sporting event, but what this is tasteless and tacky. It will make the Rugby World Cup tacky, it makes Auckland tacky and it will make New Zealand tacky in the face of a global event," Ms Casey said.
"The parade is nothing but an exploitation of women, and this one in particular is an exploitation of the Rugby World Cup, which I am sure will be shut down when the International Rugby Board hears of it."
The procession is planned for Saturday, September 24 - the day the All Blacks play France at Eden Park - through Ponsonby Rd, Karangahape Rd and Queen St in central Auckland.
"He said in his application he wants topless women painted in Rugby World Cup colours, and I think that's against the rules of the IRB," said Ms Casey. IRB spokesman Dominic Rumbles said the board "will not comment at this stage" on whether Mr Crow's event would be in breach of Rugby World Cup marketing rules.
Mr Crow said he was planning the parade in the spirit of rugby and to raise money for charity.
"At the end of it all, each girl will possibly get to decide on which charity they want the money raised from the body painting auction to go to."
Previous Boobs on Bikes had been held to promote Mr Crow's Erotica Lifestyle Expo event, and have always attracted controversy.
Opponents say the event exploits women and encourages sexual violence against women and children.
A legal bid to stop the parade by the former Auckland City Council in 2008 failed.
But Miss Erotica 2011 winner Audrey Tan, who participated in her first Boobs on Bikes parade last month, said she was looking forward to the next one.
"I don't feel the least bit exploited, if anything, it actually gives a boost to my confidence," said the 28-year-old Singapore-born porn model."I think we're all doing it just for a little bit of fun, and those who say it is exploitation are just a bunch of prudes."
