Four people are facing drug and firearms charges after police carried out a search warrant on Oriental Parade in Wellington this morning.
A 27-year-old woman and two 26-year-old men have been released on bail, but a 23-year-old man remains in custody.
They are all due to appear in the Wellington District Court on Thursday.
Wellington police and the Armed Offenders Squad searched the address about 9.30am, and the road was closed for a short time.
