A pop-up wedding is intended to be a stress-free wedding, planned by a wedding planner, who makes all of the arrangements for a one-off payment.
"The idea is that it all takes place within a two-hour timeframe and we set a minimum of 25 guests normally to keep the costs down," Ms Shaw said.
"We organise the venue, the celebrant, the photographer, the cake, you can have finger food platters included in the price if you want to, and the bubbles for the toast."
Ms Shaw ran a wedding shop for 15 years, but had to give it up two years ago, as lifting all of the heavy dresses became a struggle after two hip replacments.
"I closed the shop, then moved the stock left over back home and now I'm just selling that by appointments, which is working out okay," she said.
"Then a girlfriend of mine went to Australia for a wedding, she didn't know it was a pop-up wedding and brought the idea back with her."
Ms Shaw took the idea and ran with it, she has multiple dates booked for Palmerston North in 2018 and her first Whanganui date is pencilled in for April.
"We try to do two per day, one at 11 and one at 2, because that keeps costs down, so we do have another spot available in Whanganui on the 7th of April," she said.
Ms Shaw said that she tries to keep the price below $3000, but it depends on the cost of the venue.
"Most of the weddings that we did last year were younger couples, brides or grooms on their second time around, or couples that have children," she said.
"They want to get married, but they don't want to spend thousands of dollars."
