Open air markets on Victoria Ave and a flea market at the War Memorial Centre will run alongside the usual river market.
The bands will be back on Sunday for a day of music and food and vintage-themed activities at the Riverside Festival outside the i-SITE.
For the first time, all Vintage Weekend events have wet weather venues, so nothing will be cancelled.
"The sales are going well. There are still tickets left, though. It's a fun weekend for everyone, that's the feedback I got last year," Ms Smith said.
Also new this year is the Moonlight Movie Night with Grease being screened at Cooks Gardens on New Zealand's biggest outdoor screen.
The Sunday night event includes prizes for best dressed, American diner food and drinks, and live rock 'n' roll. Ten per cent of last year's Vintage Weekend attendees were from outside Whanganui and that number is expected to increase with Taranaki, Hawke's Bay and Wellington residents making the trip.
"It's great to see lots of people from everywhere."
