The group has launched the 'No Pelesitiki' campaign and says it has received support from the Royal household, nobles, politicians and the New Zealand High Commission.
The group's founder, Eleni Leveni-Tevi, said the traditional woven 'oa baskets were made from coconut shoots and planting was under way to increase the supply.
The plastic bag alternatives are already proving popular, Ms Leveni-Tevi said.
"So we did the launch on Monday and we sold out of all our fabric bags and our o'oa bags," she said.
