A smuggler for one of the biggest methamphetamine syndicates in New Zealand was able to obtain citizenship before officials learned of his crimes.
Xing "Alex" Su was a police target in Operation Colossus as he travelled back and forth between China and New Zealand to organise the supply of pseudoephedrine, the main ingredient in P, for a drug ring in Auckland.
He was later convicted of importing the Class C drug and manufacturing methamphetamine and sentenced to more than four years in prison in 2009.
However, the Herald has learned Su obtained New Zealand citizenship as his drug crimes occurred while the application was processed.
He was deprived of citizenship in June 2010, one of 22 cases where citizenship has been revoked in the past 10 years. Su was deported after he was paroled later that year.
