Both flags featured a koru, fern and stars in the same placement, though the colours were different. Ms Roberts went for more traditional blue and black, while Mr Hickford opted to throw bright green, red and silver in the mix.
Ms Roberts started her website in 2005 as a place to feature flags she dreamed up and discuss pros and cons of switching the design. A phone call by Ms Roberts to Mr Hickford's rural South Island home this week did not resolve any issues, as he insisted the design was started on his first computer in the 1990s. She said he later "hung up" on her.
Several entries were featuring elements of other people's work, including Kyle Lockwood's distinctive fern.
"[They] are supposed to get permission from the designer but some get away with it by just acknowledging them in their write-up. However, this is something quite different.
"There's no way the flag submitted is his own design. It would be impossible to have a design that matches so exactly."
Patricia Roberts' flag concept:
Ms Roberts said the Nelson man's concept was just too similar to her own creation, which was last changed about three years ago.
When Hawke's Bay Today contacted Mr Hickford yesterday, he defended his flag's originality.
"I got my first desktop in 1998 and started messing around with flag designs. After that I finished it in roughly 2004," he said.
"Mine is totally independent. It's similar to many others on there, with minor variations."
