Roberton Island Estate

Motuarohia Island is a peerless 1.6-acre coastal estate commanding a premier position on one of New Zealand's most revered private islands. As one of only five private residential holdings on the entire island, it offers an echelon of exclusivity that is virtually impossible to duplicate in modern coastal markets. The compound merges sustainable off-grid infrastructure with refined architectural design, surrounded by towering native pohutukawa trees and the crystalline turquoise waters of the Bay of Islands. Perfectly positioned for international buyers seeking an easily accessible Asia-Pacific sanctuary. This estate serves as a safe-haven retreat offering untamed natural beauty, security, and turn-key oceanic recreation.

PROPERTY DETAILS

At the heart of the estate is an architecturally refined single-level residence oriented toward expansive maritime views. The interior features soaring vaulted ceilings, white timber paneling, and broad floor-to-ceiling glass doors that open the home to sea breezes and sunlit lawns. An expansive open-plan living and dining pavilion is anchored by a whitewashed brick fireplace, flowing into a designer kitchen complete with stone benchtops, premium appliances, and a walk-in pantry. Accommodations in the main residence include a serene primary suite opening directly to the verandah, complemented by two additional guest bedrooms and impeccably finished bathrooms. Broad wraparound covered decks and outdoor stone terraces feature a magnificent exterior fireplace, creating an idyllic open-air lounge for entertaining beneath the stars throughout every season.

LAND AND WATER

Encompassing over an acre and a half of gently sloping coastal grounds, the property extends down to a private sandy beachfront with rare riparian rights.

The surrounding marine playground boasts two natural tidal lagoons renowned for snorkeling, along with immediate access to big-game marlin fishing, diving around outer reefs, and tranquil sailing across the bay's 144 islands. A private helicopter landing area ensures seamless sky-to-sea arrivals directly on the grounds.
