Fitbits, poor-quality portable speakers, the perennially unfashionable accessory that is the bum bag and Michelle Obama's book Becoming are tipped to be among the most unwanted gifts put up on Trade Me tomorrow.

The online auction website is traditionally inundated with users on Christmas Day and Boxing Day who want to resell unwanted presents.

"Boxing Day has become one of the best days to hit the shops both online and on foot, and over the years we've seen some epic fails listed as unwanted gifts onsite too," Trade Me spokeswoman Millie Silvester said.

Silvester's advice to those wanting to offload bad Christmas presents was to give the auction a good backstory and not too easily identifiable to avoid any awkwardness.

She ranks a pack of half-eaten Sampler biscuits, put to auction with the title "The Worst Christmas Present Ever?" in 2014, as one of the most unwanted gifts of all time on the online marketplace.

That auction garnered 180,000 views before selling for $554.

Another high-ranking unwanted gift was a $100 note, which was the most viewed list of 2015.

"Spare a thought for a woman in Darfield who received a lump of coal from her husband in 2017," Silvester said. "According to the listing, the money she raised from the auction went towards paying a divorce lawyer."

Other unwanted gifts include a 4.5kg Christmas ham, a used Christmas card and a raw beetroot.
