Tauranga's Armed Offender Squad is raiding a property in Ōtumoetai.
The house, on Ngatai Rd, is the subject of a pre-planned search warrant, a police media spokeswoman said.
She confirmed members of the AOS were on hand as a precaution.
A caller to the Bay of Plenty Times said AOS members could be seen at the property, near Bureta Rd.
