66 Mahoenui Valley Road

In Coatesville’s most coveted enclave, this extraordinary estate is more than a home — it is a destination. 

Seven acres of landscaped grounds frame a residence designed for those who value privacy, prestige, and art as much as lifestyle.


A private sweeping tree-lined drive leads to a marble and travertine foyer with koi pond, where Trinity Design has crafted interiors of drama and elegance. 

Two main pavilions rise to soaring double-height ceilings, with spaces that balance intimacy and grandeur and the formal dining room, framed by smoked glazed doors, sets the scene for elegant evenings, while the Grand Lounge evokes a ballroom with parquet floors and a striking stone fireplace.


The kitchen is anchored by an extra-long titanium polished granite island and fitted with Sub-Zero and Gaggenau appliances, flowing into the family pavilion and expansive terraces. 

Outdoors, a loggia with swing seat overlooks the pool and waterfall, while the BBQ pavilion with bar and fireplace ensures entertaining is effortless and the wellness centre is a destination in itself, offering a sauna, steam room, gym, and yoga space for restorative living, 

A separate guest suite in the pool house provides privacy for visitors.


The master suite is a retreat, with a spa-inspired ensuite and a Poliform walk-in wardrobe centred on a couture-style stone island. A lounge and balcony add further indulgence. 

 To add to the incredible offering, this home also sports a games room, a media lounge delivers the family cinema-style nights, while a floodlit tennis court and manicured lawns invite play.


Sculptures by Lachlan Ross — including Black Garden Evolve, Eternity, and Sphere — enrich the grounds, making this estate both a sanctuary and an art collection.


With curated finishes, extensive garaging, and alpacas grazing at the edges, this is one of Auckland’s finest estates — a legacy home of global calibre.
