Naz was filmed kissing two female companions at the Nines.
Former The Bachelor NZ star Nazanin 'Naz' Khanjani says she was told to cover up at the NRL Auckland Nines, with security saying her outfit was too racy.
Naz wore a black and pink sports bra and shorts to the event, where she was employed by Duco Events as an ambassador for the singles zone.
She describes the incident with security as "pathetic" and "causing quite a scene", claiming she was told to grab her things and accompany the male security guard for a private chat.
"He asked me if I had a jacket, telling me I needed to cover up a bit. I was like, 'Excuse me?'," says Naz.
"I'd seen a group of guys walking around in nothing but G-strings. That's double standards - they can't tell me to cover up but not tell the boys to cover up."
Although she's miffed at what she sees as unfairness, the fitness enthusiast does admit her 'cheerleader' outfit was revealing.
"I wasn't walking around in a G-string or with my boobs almost hanging out or anything. It was decent - well, borderline decent, with just a bit of cleavage at the top," says Naz.
"And I was showing half my arse cheeks, but God, I'm pretty sure the whole nation has already seen them on my Instagram."
Also at the Nines, Naz got hot and steamy with some of her mates in a Mai FM kissing booth.
"I couldn't find any hot guys to hook up with and I do swing both ways, so I might just take in some of my girls," Naz says in video posted to the Mai website, before stepping under a black cloth covering and kissing her two female companions.
After being spurned on The Bachelor when Jordan Mauger chose Fleur Verhoeven instead, Naz entered into a relationship with digital marketing consultant Craig Sutherland, which ended late last year.
Since then, she has been happily single and focusing on bodybuilding, but is cautious not to push it too far.
"It's nice to still look feminine. I won't go too overboard with muscles, I love curves on a woman. I love big boobs and I'm trying to grow my booty, doing squats twice a week," says Naz.
"I'm not really into Nicki Minaj, I think her ass is way too big, but I can twerk. I like everything to be in proportion."
Naz is currently preparing for the New Zealand International Federation of Bodybuilding competition in March, where she'll compete in the bikini division.
Nines organiser Duco Events has been approached for comment.
