Op shops and thrift stores are being inundated with people dropping off unwanted goods - and a new Netflix show, Tidying Up with Marie Kondo, is believed to be driving the trend.
The show has become a huge hit on the streaming service since its release on New Year's Day.
Eight episodes hosted by Japanese organising consultant and author Marie Kondo each feature a different family, who Kondo helps declutter their home.
Social media was buzzing with Marie Kondo references, tweets and memes.

There were also calls for people to take the items discarded in their decluttering missions, and donate to hospice shops or Red Cross stores.
Takanini Red Cross manager Sheryl Harris believed the show could be linked to an influx of drop-offs, following an uber-busy holiday period.

"A lady was saying to me that she'd been watching some show on Netflix about cleaning up, and she came and brought all her stuff down here," Harris said.
"Donations have been continuous every day since a few weeks before Christmas, and we're still going now."
