Australian model Jessica Gomes on her meeting with Sir John Key

Australian supermodel Jessica Gomes has revealed her fear at meeting former New Zealand Prime Minister John Key at a mall opening in Wellington in 2015.

The model and skincare brand owner is an ambassador for Australian department store chain David Jones, and is currently in Auckland to promote the store's opening in the central Auckland suburb of Newmarket.

She also came to New Zealand in 2015 to open the David Jones on Wellington's Lambton Quay - an event that Mr Key also attended.

The opening took place just months after Mr Key admitted repeatedly pulling on an Auckland waitress' ponytail, sparking calls for his resignation.

Ms Gomes told The AM Show on Monday morning she had been cautioned about his tendency to touch women's hair.

"Everyone was telling me, I didn't hear about it, but everyone was warning me he might pull my ponytail," she said.

"My hair wasn't in a ponytail, it was actually out - I was just like, you know what, I'm gonna have my hair out today.

"But he was very nice. He didn't [pull my hair] and he was actually very, very lovely."

David Jones in Newmarket is expected to open at the end of 2019.
