More than 2 billion people now use Facebook following the release of new statistics.
This means that more than a quarter of the world’s population and nearly two thirds of New Zealanders, now use Facebook every month.
The milestone comes just 13 years after the network was founded by Mr Zuckerberg when he was at Harvard University.
He famously dropped out of the university after launching the global social-networking website.
The internet giant announced it had one billion monthly active users in October 2012, meaning it has doubled the number of its users in just under five years.
There are currently 2.9 million monthly active users in New Zealand.
