Mr Abramov, who made his $US4.2 billion ($5.8b) fortune in steel and has a number of homes around the world, visited the property a year ago and is understood to be planning further trips soon.
To complement the opulent interior design guests will enjoy exploring the individual rooms of the main house, decorated with eclectic artwork and treasures collected by the owners during their travels.
Guest facilities are generous and include a gym, sauna, massage room, a 25m heated swimming pool, library, lounge areas, formal and informal dining areas and an outdoor fire pit.
Other top-end features include a health spa wing with Russian-style mosaic tiles, imported Russian and Italian furnishings and a lavish five-to-one staff/guest ratio.
Christopher Seel, Helena Bay Holdings' managing director, told NZME last year the high staff numbers would ensure guests received the utmost care and attention.
"Staff will be working in the health spa, kitchens, on housekeeping, serving, as porters, office staff, activities and amenities staff, ground staff, vegetable and landscape gardeners," he said during a sneak preview.
Another staff member said the buildings and property were so sprawling that radios and mobile phones were needed. Golf cart fleets enable staff to move swiftly around the grounds.
