The Ministry of Justice said it did not usually release information about someone's legal aid debt but in this case received permission from Sroubek's lawyer to advise that the legal aid was granted subject to a charge over Sroubek's property.
It also confirmed there were no active legal aid grants under either the name Sroubek or Antolik.
But civil legal aid could be granted for proceedings in the Immigration and Protection Tribunal.
An application to the tribunal is being considered by Sroubek's lawyer after Immigration Minister Iain Lees-Galloway's decision to reverse his original ruling that Sroubek could stay in New Zealand despite his criminal record and gang associations.
Sroubek is serving a prison term of more than five years for importing $375,000 worth of the party drug MDMA, also known as Ecstasy.
His case has caused controversy after it emerged Lees-Galloway had decided to cancel his deportation liability and grant him residency despite his criminal convictions and gang connections.
Lees-Galloway more recently revisited that decision and reversed it on the basis of new information.
Sroubek's lawyer, Paul Wicks, QC, could not be reached for comment, but has previously said Sroubek would appeal against the decision to the Immigration and Protection Tribunal.
