New Zealand businessman William Yan has been refused the chance to go to the Supreme Court over whether the police should be liable for losses incurred from the seizure of his assets.
Yan, also known as Bill Liu, is number five on China's Top 100 extradition list, Prime Minister John Key said last week.
New Zealand Police, as part of a money-laundering inquiry, seized millions of dollars of assets they believe belong to Yan, under the Criminal Proceeds Recovery Act (the CPRA), in force since 2009.
No criminal charges have been laid against Yan and he denies any wrongdoing.
Detectives are working with Chinese authorities who claim Liu stole $129 million as the chairman of a pharmaceutical company in 2000.
