Police have uncovered a "lethal cocktail" of drugs and firearms during a crackdown on Wellington criminal groups.

Seventeen people were arrested and drugs, cash and firearms were seized after police executed a dozen search warrants this week.

The arrests are part of an ongoing operation to disrupt organised crime and reduce the harm of the illegal drug trade in the region.

Wellington district covert operations head Detective Inspector Darrin Thomson said the discovery of a loaded shotgun and a stun gun in Tawa and Paraparaumu were of "real concern".

"Drugs and firearms are a lethal cocktail and this once again demonstrates the dangers of organised crime within the community. The combination of weapons and drugs pose a significant risk to police and our people."

Police also seized methamphetamine, cannabis, ecstasy, LSD, valium and $23,000 in cash.

Mr Thomson said police were committed to the fight against drugs and organised crime.

"Our operation this week should send a clear message to drug dealers and organised criminals across the district that they can expect a visit from us soon."

Police raided properties in Otaki, Paraparaumu, Porirua, Tawa, Johnsonville, Newlands, Strathmore and central Wellington as part of the operation.

A referral to Child, Youth and Family was made after a search in Paraparaumu.

Those arrested will face charges including supply of methamphetamine and cannabis, possession of drug utensils, unlawful possession of firearms and ammunition, and possession of methamphetamine, cannabis, ecstasy and LSD.

They will appear in the Porirua and Wellington district courts within the next week.
