Detective Sergeant Chris Allan, from the Northern Asset Recovery Unit, said the court settlement ordered the properties to be sold.
"While a number have been sold, 1 Apirana Ave, Whangarei has not, nor has marketing commenced," Allan said.
In total, $34m worth of property was seized after an investigation into tax evasion, subsequent money-laundering and immigration-related offending. The Whangarei property was seized last year.
"We are delighted with the outcome and the message it sends to the wider community," Allan said of the seizures.
Immigration NZ and the Labour Department also welcomed the decision.
Those who breach employment standards or exploit their workers can expect to face the combined and full effort of law enforcement, Labour Inspectorate general manager George Mason said.
"We will use every means at our disposal to ensure people do not profit from the exploitation of others," Mason said.
In 2015, some of those involved in the Masala chain were found guilty of widespread and systemic tax evasion and immigration-related offending.
Immigrant workers were often paid only $3 an hour, and Masala bosses were also found guilty of underpaying and exploiting them.
