However, Shanghai Pengxin's purchase was delayed by a successful legal challenge to the Government's initial decision by Sir Michael's consortium, which forced officials and ministers to reconsider the deal.
Yesterday, a spokesman for the consortium said they were still proceeding with a legal challenge to the Overseas Investment Office's ruling that Shanghai Pengxin's offer met the legislative requirements around the Chinese company's ability and relevant experience to own and operate the farms.
The consortium's lawyers are also poring over Friday's decision looking for further grounds for a challenge.
Sir Michael and his business partner David Richwhite moved to Switzerland in 1997 after years of allegations they had rorted the tax system and committed fraud (the wine box affair). They were cleared of any wrongdoing after a long public inquiry.
In 2007, a company owned by the pair agreed to pay $20 million to settle an insider trading case brought by the Securities Commission.
Sir Michael also achieved notoriety for making huge profits from selling shares and assets for newly privatised former State Owned Enterprises, including Telecom and Tranzrail during the 1990s.
Meanwhile, Prime Minister John Key downplayed the prospect raised by Sir Michael over the weekend that Friday's decision would open the door to a flood of Chinese investment in New Zealand farmland.
"I don't think that's actually happening at this point. It's more a perception than a reality. If that perception turned into reality the Government might want to go back and address that position."
