The apartment comes complete with state-of-the-art electronics, a home theatre system, remote control floor-to-ceiling blinds and 20 underground car parks for the new owner to park a fleet of luxury vehicles.
The walls are decked in decadent dark leather and imported Azul Bateig stone tiles, the 527sq m of internal space has polished wooden floors and the three double bedrooms boast their own stylish ensuite bathrooms with walk-in double showers and freestanding bath.
The giant main living area includes an open-plan designer kitchen featuring inbuilt espresso machine, custom-made wine racks for a connoisseur's cellar, butler's pantry and private service lift. It also features a 10m-long freestanding solid stone kitchen bench top and top appliances.
The freehold apartment's 415sq m of outdoor decks face north, west and south and has views of the Hauraki Gulf, Rangitoto Island, the North Shore coastline, Waitakere Ranges and Manukau Harbour. It also provides a bird's eye view of downtown Auckland and dramatic vista of the Sky Tower.
It comes with a concierge service and its own rooftop herb garden, but body corporate fees, rates and insurance will set the owner back about $80,000 a year.
The property, which has a 2011 valuation of $5.48 million, was previously owned by former Chase Corporation director Peter Francis, who is understood to have poured about $3 million into a luxury refit.
QV records show it was bought in May by Mr Magides' company New Zermatt Properties.
The agent who handled the sale, John Greenwood of Sotheby's International Realty, believed it was a record price for an apartment and described the penthouse as the best he had seen. Its outdoor space and high spec features set it apart from other luxury apartments.
"This is the number one."
Mr Greenwood said the property would have attracted international interest but the sale was "very much an off-market arrangement". He would not divulge details of either the vendor or purchaser.
Essex University-educated Mr Magides has been based in Singapore for many years.
In 2002 he co-founded Asian hedge fund Artradis Fund Management, which was worth US$4.5 billion at its 2008 peak before being closed down in 2011.
He was granted Overseas Investment Office approval in 2012 to buy a Bay of Islands vineyard and develop a luxury accommodation wine retreat in a deal worth about $6.2 million.
The former Barings Bank trader was granted consent last year to buy 2737ha of Ben Avon Station in the South Island and develop an exclusive eight-room luxury wilderness lodge offering guided hunting, fishing and horse riding in a deal worth about $6.5 million.
The Metropolis penthouse sale follows the listing of a refurbished 29th-floor penthouse in the Sentinel apartment building on the North Shore. It is expected to fetch well over $8 million.
