Wairarapa Police's Precision Targeting Team arrested a woman this morning in relation to the supply of methamphetamine.
The 24-year-old woman was located at a gang-affiliated address in Carterton during a pre-planned search warrant.
The woman is due to appear in the Masterton District Court tomorrow on a charge of possession of methamphetamine for supply.
Police seized approximately 660 grams of methamphetamine, which is equivalent to about 33,000 doses and worth approximately $230,000.
About $37,000 in cash was also seized by Police.
Detective Senior Sergeant Philip Skoglund says removing this amount of methamphetamine from the market may have prevented up to $730,000 worth of social harm.
"This seizure is a great result, and we are committed to disrupting the supply of illicit drugs in our communities."
Further arrests in relation to this offending are likely.
