Van Ness calls the woman "a super sweet lady" in his caption where he reveals he signed a few of his products for fans to nab from the Auckland store.
"I asked this super sweet lady if she needed help finding anything and signed a few boxes if you wanna grab them Auckland."
The video has received almost 40,000 likes and nearly 500 comments including: "Omg haere mai (welcome)!!!!" and "Welcome to New Zealand you gorgeous person."
One commenter asks how the woman stayed so composed: "She held it together so well I would be a mess," they said of the chance of meeting Van Ness, who found fame on Netflix series Queer Eye as the show's "grooming expert".
He's also known for his work on Gay of Thrones, a web series parody show, and hosts podcast Getting Curious with Jonathan Van Ness.
Van Ness was in Auckland for his live comedy show The Imaginary Living Room Olympian at The Civic theatre last night.
According to an audience member, Van Ness received a standing ovation for his performance.
