The haul included about 434kg of methamphetamine, 407kg of MDMA, and 8kg of cocaine.
As international crime syndicates seek to exploit top-dollar prices in New Zealand, police and Customs are nabbing bigger busts of illicit drugs. Chelsea Boyle looks at some of the biggest hauls in the last year.
August 2019 - mega meth bust
Two British nationals in Auckland were allegedly busted with more than 200kg of methamphetamine - worth about $144 million on the street market - after police targeted members of an international crime syndicate.
Police arrested a 60-year-old British man after raiding a central city apartment and allegedly finding a wardrobe full of cardboard packing boxes which contained methamphetamine.
The second man, 49, - who police allege assisted the first - was arrested at the airport as he allegedly tried to flee the country.
Both are due to appear in court in the coming weeks.
August 2019 - snow on Bethells Beach bound for Oz
About $3 million of cocaine, believed once destined for Australia, washed up on Bethells Beach in West Auckland and was discovered by locals walking along the shoreline.
Police found 20 tightly wrapped blue packages of cocaine at the scene.
In August 2018, occupants of a rigid inflatable boat off the northern New South Wales coast were seen offloading cocaine into the sea and were arrested.
New Zealand police believe the cocaine found on Bethells Beach appears to have been part of the same shipment, as both the markings and packaging of the drugs was consistent with that seized in Australia.

More than 150 police staff performed search warrants at 17 residential and commercial properties throughout the wider Auckland, Canterbury and Southland districts.
Auckland suburbs targeted included New Lynn, Blockhouse Bay, Avondale, Manukau, Mt Eden, Grey Lynn, Karaka, Greenlane, Manurewa and Northcote.
Several high-end vehicles including a Porsche Macan, Jeep Wrangler and three Harley Davidsons were seized during the raids.
Jewellery, including a necklace worth more than $70,000, was also seized.
July 2019 - dirty cash & a 'sophisticated' meth scheme
Two Australian men were arrested as Customs seized up to 100kg of methamphetamine with a street value of up to $50m.
The duo allegedly imported and possessed between 70kg and 100kg of methamphetamine, hidden inside plastic storage pallets.
Customs said the concealment method used "quite sophisticated and not easily identifiable".
The search of the West Auckland home of one of the accused allegedly uncovered up to $50,000 cash, hidden inside a dishwasher and inside a backpack.
June/July 2019 - logging vessel Bunun Justice raided in Tauranga
Two men were busted in Tauranga after allegedly importing 25kg of ephedrine.
Customs officers patrolling the Port of Tauranga questioned a 33-year-old who arrived on the logging vessel Bunun Justice on June 28.
When he attempted to return to the ship, Customs officers advised both he and the Bunun Justice would be searched - a decision that allegedly uncovered 13kg of ephedrine.
Investigations linked the man to a second male in Tauranga, also a foreign national, who was allegedly discovered with 12kg of ephedrine in his possession.
Customs investigations manager Bruce Berry said the two arrests were the result of "quick thinking".
Both of the accused men have pleaded not guilty in court.
May 2019 - Kiwis and cocaine paste
Two New Zealand nationals, a Hamilton man, 30, and an Auckland woman, 20, arrived back in the country from Argentina on May 5.

The cocaine would have had a street value of about $2.1m in New Zealand.

2018 - the banana container bust
Police and Customs found more than 190kg of cocaine parcelled within five duffel bags and stowed on top of banana boxes inside a shipping container in August last year.
It was the biggest bust of the drug in New Zealand history.
The cocaine had an estimated harm value of more than $235m and would have had a street value of $28m to $36m.
