Wellington police have seized crystal methamphetamine they say has a street value of more than $1 million.
The discovery came as police searched more properties following last week's raid on a Chews Lane apartment in the central city.
Police on Wednesday said they had executed another three search warrants at inner-city addresses and seized more than $1 million of crystal methamphetamine, or P, along with four vehicles and $30,000 in cash.
Detective Inspector Darrin Thompson said the drug supply chain had been disrupted, meaning dealers would have to find alternative suppliers.
"It disrupts the chain considerably because they've got to go and find another seller along the way who may not be as sophisticated," Mr Thompson said.
"What that creates for us is more opportunity to get in and disrupt them and try and stop the misery that they're causing in the community."
The results were a continuation of operations which started with the seizure of $2 million of methamphetamine in December.
Meanwhile, bail has been refused for one of the people charged after the original raid last Friday.
Four people appeared in court on drugs charges after the Chews Lane raid and one, Puthy Chea, 29, was refused bail.
Judge Peter Hobbs remanded Chea, who was charged with possession of methamphetamine for supply, in custody until 28 March.
The other three people arrested in that raid will also appear in court that day.
