Twenty-two people, including patched gang members, have been arrested in Northland this week after a methamphetamine investigation known as "Operation Ghost".
Police executed dozens of search warrants over the past three days in Whangarei, Dargaville, Kawakawa, Moerewa, Kaikohe, Kaitaia and Awanui as part of the operation, which has been running since November.
Eleven males and 11 females aged from 18 to 57 will appear in court on a range of drug and other charges.
Several of those arrested are patched gang members or gang associates.
