Miss Gollan, a nurse, had always wanted a caravan and when she spotted Hettie for sale on Trade Me, she knew she was perfect.
She purchased her in Raumati for $4500 - a bargain for a star. Hettie featured in the 2008 New Zealand movie Second Hand Wedding and sleeps three people.
Miss Gollan said Hettie's name was short for Harriet. "I had just returned from doing a nursing contract in Alice Springs and managed to save a bit of money, part of [which] went towards the caravan," she said. "The place I was working in was called Hettie Perkins and I thought it was a cute, old-fashioned name that suited the caravan."
Inside, Hettie's floor is black and white check, and a vintage theme stretches from pastel wall motifs of birds and butterflies to bunting and floral cushions.
Mr Garcia, an accountant from Argentina, has been on a working holiday in New Zealand for 11 months.
This is the 29-year-old's first time holidaying in a caravan and he said Mount Maunganui was the best place he'd visited in New Zealand.
