The representative kickboxer had claimed he had to flee his homeland in fear of corrupt officials after he witnessed a murder.
On hearing the evidence, Judge Wade was convinced that he would still be in danger from corrupt Czech authorities and the man he helped convict if he were deported back.
"I am satisfied that your initial false applications were as a result of you doing the right thing, not the wrong thing," Judge Wade said in sentencing Sroubek in 2012.
"Furthermore, had you been frank with the authorities when you first came here, it seems plain that you would have been granted a work permit and, ultimately, residence in any event, on your own merits."
Sroubek used his second chance to smuggle 5kg of MDMA, a Class-B drug, into New Zealand from the Czech Republic.
The drugs had a street value of about $375,000.
Sroubek appealed against this conviction but in December 2017 that was dismissed.
The conviction meant he was automatically liable for deportation.
Immigration officials told then Immigration Minister Iain Lees-Galloway there were two matters for which Sroubek could be deported: the conviction for importing MDMA, and the use of a false identity to come to New Zealand.
Sroubek's fear of returning home seemed to be behind Lees-Galloway's controversial decision to cancel his deportation liability.
The decision quickly became a political firestorm.
Lees-Galloway revisited the case after it emerged that Sroubek may have travelled back home, and following reports that his estranged wife no longer supported his residency bid.
During the investigation of the case and the confirmation of convictions in the Czech Republic, the minister found Sroubek liable for deportation on the basis that he was an excluded person.
An excluded person is someone convicted and sentenced to jail for at least a year in the 10 years before arriving in New Zealand.
It was therefore deemed he was granted residence as a result of administrative error.
A review conducted by Michael Heron QC noted that the grounds to deport Sroubek from the beginning were "sufficiently powerful" and Lees-Galloway's initial refusal to do so was "unexpected".
Heron made several recommendations including that Immigration NZ should be able to make inquiries into deportation cases if the minister asked them to.
