Ms Armstrong, a doll maker and teacher, has entered the Dunedin Shanghai Association's Chinese social media competition, promoting Dunedin as a tourist destination to Chinese tourists.
The idea was to mark both the China New Zealand Year of Tourism and the 25th anniversary of the Dunedin-Shanghai sister city relationship.
The competition has been extended to November 15 and carries $3000 in prize money.
Armed with a toy penguin and "Jilly" the doll, Ms Armstrong has been filmed in various places around the city including Blackhead Quarry, the Chinese Garden, Larnach Castle and Baldwin St.
The end result of her "No8 wire" approach would be a video of several minutes promoting Dunedin and it had been "so much fun", she said.
"At the end of the day, we're wonderful here ... the history is phenomenal. It's storytelling, one of my favourite hobbies," she said.
