Members of public who have spotted armed offenders in the city this morning can be rest assured there is nothing to worry about.

SunLive has received a number of calls from people who have seen AOS members at the Whakamarama Shops, near Whakamarama Rd.

One caller says she passed the shops and saw a dozen cops and officers wearing full AOS suits.

A police media spokeswoman says that the AOS are currently part of a planned operation.

'This is a routine pre-planned search warrant that the AOS are assisting at,” she says.

This is a second day in a row armed police have been spotted in the Taurnaga/Western Bay area.

Yesterday, a SunLive reader emailed in to say armed police had blocked off Waimapu Pa Road.

Police says yesterday's operation was also a planned search warrant.
