Two days into a major operation searching two properties near Whangārei police are keeping mum about what they are doing.
Up to 20 police officers, several of them armed, swooped on two properties on State Highway 14, in an area known as Wheki Valley, 21km southwest of Whangārei, on Monday morning.
One property had a half-round haybarn and containers on site and the other was a house at the end of a track just a few hundreds metres away on the state highway.
Officers at the scene said they were unable to comment and, in a written statement, police were said they were carrying out multiple pre-planned search warrants in Northland as part of an ongoing operation.
