Methamphetamine worth $9 million was found hidden in a coffee table sent from Hong Kong, destined for a Wellington address.
Customs found 15 packets of drugs in the table.
Enquiries by Customs and police are continuing but no arrests have been made.
Customs investigations manager Maurice O'Brien said the find had removed methamphetamine from the drug supply chain and prevented subsequent harm to communities.
"The drugs were carefully concealed to try and avoid detection, but our officers are vigilant. Customs has good risk-assessment systems and significant seizures continue to be made.
