A large contingent of police, including at least four carloads of Armed Offenders Squad members, searched a Te Puna address last night.
Police remained tight-lipped about the reason for the search.
But a police spokeswoman earlier told the Bay of Plenty Times Weekend that officers were carrying out a "pre-planned" search warrant operation.
While the Armed Offenders Squad (AOS) was assisting, there was no danger to the public, but they were asked to keep away while police carried out the operation, she said.
Callers to the newspaper earlier said they had seen at least 14 police vehicles speeding west along State Highway 2 about 5.10pm.
Detective Senior Sergeant Greg Turner would not publicly comment on the reason for the search.
