The land was listed for sale on Wednesday and Mr Gregory expected international and domestic interest.
The site's annual Queenstown Lakes District Council rates are about $1695 and its rateable value is $1.65million.
However, Gregory expects the land will sell for "north of that''; one website has advertised the sale price as $1.85million.
Building consent was required for the rural lifestyle-zoned site, which included Doc protective covenants, but resource consent was "in progress''.
