For more than three years, the pair behind Auckland fashion label Federation imported deliberately undervalued goods from China.
The scheme saw them evade Customs fees of $680,000, while products brought into New Zealand were undervalued by more than $2.8 million.
At least $190,000 is still owed to Customs, a court heard today.
Former company director Nicholas James Clegg, 43, appeared in Auckland District Court this afternoon after admitting nine charges, which amounted to 114 erroneous entries made under the Customs and Excise Act.
He was stung with a bill of nearly $9000 - made up of fines, court costs and ministry solicitors' fees.
