The prospect of bare breasts on a Saturday is the last straw for Family First.
The lobby group is furious at plans for a Boobs on Bikes parade in Auckland, on the day the All Blacks play France in the Rugby World Cup.
Steve Crow is planning a "rugby special" Boobs on Bikes parade with girls body-painted in world cup team colours.
Family First says police and councils have been very liberal about weekday topless parades.
Spokesman Bob McCoskrie says having the parade on a weekend when many families with children will be in the city will cause widespread offence.
The Auckland Council confirmed that an application for a permit has been submitted, but has not yet been issued.
Auckland Councillor Cathy Casey has spoken against the idea, saying it will make New Zealand look tacky.
The procession is planned for to travel through Ponsonby Rd, Karangahape Rd and Queen St in central Auckland.
Mr Crow said he was planning the parade in the spirit of rugby and to raise money for charity.
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.
