The 2020 Vintage Fair, usually held in January as part of the Whanganui Vintage Weekend programme, will spring into action again in September.
Vintage Weekend event manager Heather Cox said stallholders suggested a mid-year event as a fundraiser, as many of them still had lots of stock to sell.
"They're collecting things all year round that they then polish up and sell at the Vintage Fair," Cox said.
"Because they have so much stuff coming through they said they could easily have another event during the year, one where they could sell off their stock and find new treasures.
"We thought that it would be a great fundraising opportunity for us as well, so it's a win-win situation for everybody, really."
