He was sentenced last year by the court to 400 hours' community service and a year's home detention, although he was later permitted to go to work.
He admitted to the tribunal that his court conviction on 16 fraud charges reflected adversely on his fitness to practise medicine, and this was the basis for its disciplining him.
Kong faces two other court actions.
The health board has started civil action in the High Court to recover more than $1 million from him. When the case began, Kong pleaded not guilty to 21 charges relating to $1.3 million.
He had also pleaded not guilty to a charge of obstructing the course of justice, which relates to his allegedly altering a clinic file. The Health and Disability Commissioner is said to have cleared Kong over a cancer case complaint after relying on the file.
Kong was discharged on that charge, but the Court of Appeal ordered a retrial, which is scheduled to start next August.
