The Remuera property was purchased by interests associated with Hotchin for $8.1m in 2017, and building consent records indicate it subsequently underwent two years of renovations costing more than $1m.
Records indicate $280,000 was spent demolishing and rebuilding a five-car garage, and another $850,000 went on redoing the kitchen and installing a spa pool.
A request for comment sent by the Herald via Dwayne McGorman, Hotchin's long-time accountant and the person responsible for the companies office filings, went unanswered.
The house had previously been advertised for rent, with listings describing the property as "Hollywood comes to Remuera" and an "iconic 1930s Spanish Mission Estate". The listing also make special note of a "weighty 1930s-style chandelier" and "secret doors in the cabinetry".
The property, with a current rateable valuation of $8.6m, was previously called home by another colourful business character.
Jihong Lu - who in the 90s claimed to be heading a billion-dollar redevelopment of Britomart but was later bankrupted, before returning from obscurity to produce the epic theatrical flop City of 100 Lovers - lived in the house in the early 2000s.
The Remuera address shows up as Lu's residence, related to his directorship of a company in the Bahamas, in a leak of international trust company records known as the Paradise Papers.
