A $35 million "chateau" has been on the market since the summer - and still the buyers have failed to materialize.
Almost half a hectare of Takapuna land with a vast house of just under 2000sq m has been up for grabs in Auckland since at least February - and it's being marketed as possibly the "finest private residence" throughout the country.
Top agent Graham Wall has throughout the year been marketing the exclusive Clifton Rd property overlooking the Hauraki Gulf.
It has a whopping nine bathrooms, five bedrooms and parking for eight cars - as well as three hidden panic rooms built-in to keep the occupants safe.
Mr Gregory is a former shareholder of Metro Glass Tech which was sold for $366 million in 2006 - reportedly leaving Mr Gregory with more than $100 million.
He put his $4.5 million Bay of Islands holiday retreat on the market last year to tick off some of his bucket list, including an extensive US road trip and sailing on the Mediterranean with his family, the National Business Review reported.
A video marketing the Takapuna mansion shows the coast-top home tucked down a private driveway, with magnificent views overlooking Rangitoto and a column-filled lounge.
Multiple outdoor seating areas and sculptures are visible as well as a garage which is packed with classic cars.
The latest capital valuation of the home is a mere $16.5 million but the property is on the market for more than double that price.
It is expected to go for a few million less than Auckland's most expensive house - a seven-bedroom Paritai Drive mansion partly financed by Hanover Finance director Mark Hotchin - that went for $39 million in 2013.
