Customs investigations manager Maurice O'Brien said criminals were creative in their attempts to bring drugs into the country but authorities would not be deterred by elaborate presentation and delivery methods.
The package and other offending were subsequently linked to Ching who had arrived in New Zealand a week before the statue.
Customs arrested her at a central city apartment she was renting.
Mr O'Brien said it was not uncommon for syndicates to recruit young people from overseas and pay for them to travel to and reside in New Zealand solely to "catch" and redeliver illicit drugs.
"The public should be aware that such criminals could be renting properties or apartments solely to have packages delivered to that address, or asking others to receive a package on their behalf," he said.
