More drugs were seized at Auckland Airport in the first four months of last year than across all airports in the country, in the entire of 2024.

It’s part of an exponential rise in the amount of drugs being intercepted at the border - with the volume more than quadrupling between 2018 and 2024, from 1.5 to 6.5 tonnes.

The figures are outlined in a Cabinet paper, obtained by Newstalk ZB under the Official Information Act.

Customs Minister Casey Costello has also revealed in the first nine weeks of this year, more than 12 tonnes of cocaine has been intercepted in the Pacific.

She said the agency’s international relationships had helped combat international drug trafficking.

But she said “unfortunately there’s just so much more around. We’ve seen in our wastewater results, there is just a huge amount of drugs”.

Costello said the increase has been notable over the last 10 to 15 years, as drugs are becoming cheaper to produce and being produced in greater volumes.

“This idea that New Zealand used to be far away and that we are somewhat isolated - that’s not the case anymore,” Costello said.

“Supply chains and technology means that we’re being hit hard.”

Officials estimate illicit drug harm carries an estimated social cost of $36.7 million each week - or $1.9 billion each year.

A Ministerial Advisory Group on transnational and organised crime estimated $1.6 billion in profit is generated through drug crime and fraud annually.

The paper states agencies were increasing efforts to reduce the flow of illicit drugs and other illegal products into communities, and noted the Government has supported an improved response through an increase to the Customs budget last year.

Costello noted a particular increase in methamphetamine, saying New Zealand has one of the highest retail prices for meth in the western world, and was a “very lucrative market” to big business cartels and organised crime networks.

“There isn’t one part of the border we need to strengthen. It’s coming through small packages and parcels. It’s coming through container freight. It’s coming through couriers that traffic it through the airports. It’s coming through unaccompanied baggage - every way in which they can circulate it.”

Costello said the Government was working on a collective, collaborative approach, where agencies can work together on the response to organised crime.

She admitted it was a “difficult environment” when it came to securing more funding in the upcoming Budget, but said other practical steps are taking place, including working on information sharing to dismantle cartels.

“Al Capone got taken down by tax evasion. It is literally that kind of approach,” Costello said.

“Every lever we can pull, we should be able to pull.”

She applauded the work of agencies intercepting and disrupting the transnational drug trade, stating she gives credit to those front-line workers that are “doing so much.”

Costello said the country was fighting “such a big enemy.”

“I do really applaud the agencies. We’re not winning, but I wouldn’t say we’re losing.”

The Cabinet paper highlighted the importance of this work on economic growth, as disrupting transnational and organised crime groups can maintain New Zealand as a “trusted trading partner” and a safe destination for tourists.

The importance of “robust accountability” is detailed throughout the document, which suggested New Zealand was “well-placed to be world-leading” in its response to transnational crime due to a single enforcement agency and its legal system.

But officials noted “our current response is fragmented,” and reiterated the importance of co-ordination across agencies.

It comes after the Government agreed on a set of actions to address meth-specific harm, which specifically calls for Customs, the Defence Force, and the GCSB to undertake maritime operations to disrupt organised crime across the Pacific.

Prior initiatives responding to organised crime showed a return on investment of $3.40 for every dollar.
