Detective Senior Sergeant Tim Leitch, head of the Wellington drugs and organised crime team, said the seizures added up to more than $1 million in prevention outcomes.
"We are delighted to seize this large quantity of drugs and cash and its seizure has significantly reduced the harm to our community," Mr Leitch said.
"We will act with urgency to identify those involved in serious drug dealing and seize the opportunity to reduce the risk these drugs pose as well as hold those who deal them to account."
