A police officer at the market was summoned but police were unable yesterday to confirm whether any action was being taken to identify or find the man.
Mrs Gray was able to give a comprehensive description of a man she described as Asian, with a navy-blue hat, blue "knitted" polo shirt with red diagonal stripes but no logo, dark trousers and black "sneakers" with yellow-and-black laces.
It didn't turn Mrs Gray off the market day, which attracted an estimated 15,000 people, but she said it had been "somewhat soured" by the disturbing event.
"You feel violated."
However, she said the Haumoana Market Day was a "great family day out and I will be back again next year". But she would "certainly be paying more attention to who is around me".
Hawke's Bay has a notorious place in up-skirt camera voyeurism, dating back to the internationally quoted case of classic-cars buff David Overend in 1997.
He was apprehended having photographed up the skirts of more than 2000 girls at large public events. He apparently cut a hole in a toe of a shoe in which he hid what was described as a "pin-hole" camera. He was sentenced to 21 months' jail.
