In 2018, there were 20,000 unwanted presents listed and 100,000 searches registered on Boxing Day as opportunistic sellers and bargain hunters jumped onsite.
A word of warning, though, for the boomers before they get steaming mad at the woke youngins for reselling gifts - Kiwis do it more often than our cousins across the Tasman.
New Zealanders are much more likely to trade off unwanted presents at 43.6 per cent compared to Australians at 38.4 per cent.
If you find a friend or loved one is passing on something you bought for them, it might be worth buying a voucher for them next time.
"Kiwis love vouchers, with nine out of 10 of us chuffed to receive a voucher for Christmas," LayBuy co-founder Alex Rohloff said.
"Our research shows that New Zealanders enjoy receiving vouchers and despite what some people say, we don't see them as a Christmas cop-out.
"The best thing about vouchers is the person receiving the voucher can buy whatever they want, and with Boxing Day sales now in full swing, it's the perfect time to get out and cash in on the deals."
Launched in Auckland in 2017, LayBuy has partnered with more than 7500 retailers and is available in New Zealand, Australia, and the United Kingdom.
The buy now, pay later provider offers customers the chance to shop now and receive their purchases before paying them off over six weekly payments without interest.
