Legal high godfather Matt Bowden is now living in Thailand and his company's liquidators say they have been unable to contact him.
Bowden put his company, Stargate Operations, into voluntary liquidation last year when he couldn't afford to pay his bills and was locked out of his lab where he made synthetic cannabis.
Creditors have claimed more than $3.6 million from the failed firm.
Inland Revenue wants more than $1 million and 22 unsecured creditors say they are owed $2.2 million. Employees have claimed $457,000 in wages, redundancy, bonuses and holiday pay. Of this, about $137,000 has been paid.
Stargate's liquidators, however, have recovered just under $310,000 after selling the company's assets and recovering loans and other debts.
