Yesterday at the house, Inglis declined to discuss the sale. She said Brown was home but the family was busy decorating the Christmas tree and couldn't talk.
The house features on several websites including Trade Me, realestate.co.nz and in local property publications, but there are no photos of the interior.
There are several photos of the brick-and-tile profile of the multistorey home, its contoured landscaped backyard, in-ground swimming pool and tracks through lush bush.
"That was what they requested, given the profile of the owners," said agent Paul Barrett.
Viewing was strictly by appointment only.
Barrett said the substantial home and property was too big for the Browns and they wanted to find something smaller.
He had no indication of the couple's next move, saying they wanted to sell the property "then their plans will firm up".
The secluded bush-covered 0.7ha property has seven bedrooms and four bathrooms, including a two-bedroom granny flat.
"This magnificent property will appeal to the most fastidious of buyers who love nature and want a large quality residence," the listing reads.
The property was custom built for the couple in the mid-1990s and carries a rates bill of $3693.76.
