Topping the list is the Orakei mansion partly financed by former Hanover Finance Mark Hotchin, which sold for $38m in 2013.
A Takapunua home sold for $28m in 2005, $28m was spent on a Herne Bay property last yar, while a home in Hauraki, on Auckland's North Shore, commanded a $22m price tag earlier this year.
At the time of the Dotcom mansion sale, the Barfoot and Thompson agent who sold the property said she was thrilled with the price and had taken dozens of genuine buyers through the super-sized home.
In a previous interview Christina Tang said she had around 50 genuine buyers through the property which she said was a large number for such a prestigious property.
The sprawling estate has a 2015 council valuation of $23.55m but was previously expected to sell for around $35m.
Tang said both the seller, Chrisco multi-millionaire Richard Bradley, and the new owner were "thrilled with the result".
The sprawling estate - also known as the Chrisco mansion - has 12 bedrooms, is on 22.6ha with its own vineyard, lake and boathouse, and has manicured parkland and sculptures.
A expansive hedged maze, an olympic sized swimming pool and giant corrugated iron giraffes add to the spectacle of the property.
It was built by Bradley but really hit headlines when Dotcom moved in.
Dotcom moved into the mansion with his then wife Mona and their three children in 2010 and paid a reported $1m a year in rent.
He ran his file-sharing website Megaupload from the mansion and in 2012 the luxury pad was raided by armed police in the early hours of 20 January. Mona Dotcom was heavily pregnant with the couple's twins at the time.
Dotcom is now renting a waterfront apartment in Auckland.
