Armed police have arrested four people in a raid on a known drug house in Grey Lynn.
A police team, including several Armed Offenders Squad members, executed a search warrant at the Tuarangi Rd house at about 8am this morning.
They arrested two men and two women on charges relating to the possession and cultivation of a class C drug, police said.
One of the arrested men was already due to appear in court today to be sentenced on previous charges, including possession of class C cannabis for supply, supplying a class C drug, setting a man trap, and theft of electricity.
Police spokeswoman Noreen Hegarty said the man owned the house and was at the "centre" of the alleged drug offending.
