Harcourts marketing agent Aaron Davey said the home was bought by an Auckland boss who was already living in Hamilton and wanted to upgrade.
The 10-year-old property was last sold in 2009 for $1.85 million and has a current capital value of $2.58 million as of last June.
Mr Davey said Aucklanders were eyeing up properties north of the city and they ranged from people wanting to commute, professionals with young families relocating or retirees selling up in the big smoke and buying an impressive property while still having cash to spare.
The record for the most expensive home within 10km of Hamilton is held by a Tamahere property which sold for $3.6 million but had 10ha of land.
More comparable are sales in 2014, with a Flagstaff house going for $2.975 million and a Tamahere home at $2.8 million.
But Hamilton's priciest properties are a drop in the bucket compared to Auckland.
CoreLogic senior research analyst Nick Goodall said Auckland was a completely different market.
“Over the last couple of years we are seeing two very different markets. Auckland is very much more of an international city these days. More comparable to the likes of Sydney, Melbourne even, and cities on the western coast of America.”
