A Free the Nipple event set to take place on Mission Bay next week has been slammed by watchdog group Family First.
The event, which more than 500 people say they are attending on Facebook, aims to "desexualise the female body."
"This is a chance for us to act for equality and enjoy a summer's day at the same time, so come along and let your nipples get some sun," the event's description reads.
However, Family First's Bob McCoskrie says the event is inappropriate.
"Obviously we [Family First] would be opposed simply because families would find it offensive."
A spokesperson for the New Zealand Police said they deal with issues like this on a "case-by-case" basis depending on any complaints they get from members of the public.
They said it is hard to determine in advance whether an event such as this would lead to any arrests.
Mr McCoskrie criticised the police for taking a hardline position on streakers at public sports matches, but for often being relaxed over nudity such as this.
He said that it was "questionable" whether an event such as this would be legal.
The organisers of the event have been approached for comment.
Free the Nipple: Beach Day is set to take place on December 17th.
