The island has been a favoured getaway for Zuckerberg, 30, who was spotted there last year with his wife, Priscilla Chan. They ate at a favourite local restaurant called Bubba Burgers and were spotted surfing.
Zuckerberg is believed to have already bought several multimillion-dollar flats in Hawaii. His latest purchase includes a 144ha plantation, including around 790m of land that stretches along the sea front. According to Pacific Business News, it was put up for sale in August with a price tag of US$70 million along with planning approval for the construction of up to 80 houses.
The second purchase is a 140ha section of land next to Pila'a Beach, which was sold for US$49.8 million according to an analysis of property records by Forbes magazine.
The new owner has permission to build five homes on the land, but Zuckerberg is not believed to want to develop it. He reportedly plans to build a home for himself and his family, and use the rest of the space to secure his privacy.
He will have one neighbour, a Denver-based businessman who still owns a 10 per cent section of one of the parcels of land Zuckerberg bought.
Mr Zuckerberg, who is worth around US$33 billion, is the second Silicon Valley billionaire to buy up part of Hawaii recently.
Last year, Larry Ellison, the chairman of Oracle, the computer technology corporation, purchased the whole of Lanai, Hawaii's sixth largest island, for up to US$600 million.
The Hawaii purchase is Mr Zuckerberg's latest leap up the property ladder.
In 2010 he was renting a modest property near Facebook's headquarters in Menlo Park, California.
The following year he upgraded to a US$7 million, 465sq m residence in Palo Alto, California,
The businessman then spent US$30 million buying four homes adjoining his own property in Palo Alto to fend off a developer who was going to purchase them and market them to potential buyers as being "next door to Mark Zuckerberg".
