The Herald on Sunday went mystery shopping on Auckland's Ponsonby Rd, with fashionable 23-year-old Malaika Meder, a size 16.
Posing as a shopper wanting a dress for a party, Meder put retailers to the test. She found few options and received some frosty receptions from staff.
The issue was sparked by Herald on Sunday columnist Wendyl Nissen, who encountered similar problems in Ponsonby.
"Plenty of women who are size 14 or 16 exercise regularly, eat healthy and don't drink too much. It's just a shame we're missing out on dressing nicely," Nissen said.
Attitudes continued to surprise, after all a size-14 Whitney Thompson won the 2008 series of America's Next Top Model.
