Simons flew into Queenstown yesterday, then travelled to Cromwell, where she was speaking at a function organised by Paper Plus owner Mike Paardekooper.

"Landing at the airport was quite interesting. That was enough adventure for me for a lifetime."

"I'm aware [of popularity] when I come. I get a lot of people coming up to me and just being so happy and enthusiastic," Simons said.
