"Mr Yan was not interested in becoming involved in litigation over the property ... he exercised the rights held by him as mortgagee to sell the property," wrote Justice Edwin Wylie.
So Albany Heights was sold for $4.3 million to an Auckland company financed by Ease Treasure Ltd, registered in the tax haven of the British Virgin Islands, according to property records.
Ease Treasure Ltd has no visible links to Mr Yan but is mentioned in paperwork seized by police investigating him for alleged money laundering, according to court documents obtained by the Herald.
Handwritten in Chinese, the note authorised the purchase of $1.85 million of shares in Ease Treasure Ltd and was signed by Yang Liu - a previous name of Mr Yan.
Another piece of paper contained an instruction to an Auckland-based foreign exchange company to transfer US$500,000 ($640,000) to an Ease Treasure bank account in Hong Kong.
The money-laundering case against Mr Yan is linked to an alleged $129 million fraud in China, which is one of the reasons that Internal Affairs officials recommended that he should not receive citizenship.
No criminal charges have been laid against Mr Yan. His lawyer, Paul Wicks, QC, said his client denies any wrongdoing.
Detectives raided Mr Yan's luxury penthouse in August and seized at least $40 million of assets using the Criminal Proceeds Recovery law, which essentially forces someone to prove how an asset was paid for.
