The nude female streaker who frolicked around in the parade ring at Day 4 of the 2018 Karaka Yearling Sale is former The Bachelor NZ contestant Harmony Moki.
Video of her naked performance, which includes two cartwheels, has been widely shared on social media.
Moki, who is a jockey, wouldn't comment to Newshub about the incident, but did publish a humourous Instagram post that appears to be about it.
"Can't blame wine entirely, mostly it's coz I'm a dick," she said in one reply.
The video was posted online by Rob Waterhouse, husband of champion trainer Gai Waterhouse, who joked: "An unusual and appealing lot going through the Karaka sale ring in NZ: an athletic, precocious type, good stride -plenty of bounce, if a shade frisky."
The streaking or 'nudie run' reportedly became the talk of the multi-million dollar horse sales event.
Moki was a contestant in the 2016 series of The Bachelor NZ, which ended with Jordan Mauger giving Fleur Verhoeven his final rose.
