Last year Alibaba made US$17 billion (NZ$24.5b) in sales from Singles' Day, more than three times the amount made for the US equivalent of Black Friday.
Singles' Day, or 11.11, started as an obscure "anti-Valentine's" celebration for single people in China in the 1990s, and has now become the biggest online shopping day in the world.
On Friday evening Alibaba founder Jack Ma hosted a glitzy countdown gala headlined by US rapper and singer Pharrell Williams, Chinese actress Zhang Ziyi and a string of other celebrities and influencers.
The retail gala, which was watched by more than 400 million people in China last year, is part of Ma's vision for the future of retail - merging entertainment and consumption.
Alibaba rival JD.com made NZ$27.6b (US$19.1b) on Singles' Day, up 50 per cent from last year.
