Coroglen Tavern part-owner Luke Findlay had not long closed for the night yesterday when he saw three police vehicles with Armed Offenders Squad members travelling to a property near the pub 16km south of Whitianga.
He understood a person with a gun had been seen on the driveway of the property, Findlay said.
“There’s AOS up at the [property], and three police officers here [outside the tavern] and cops either side of the Whitianga and Coroglen sides of the [State Highway 25] highway … and the [police] helicopter’s going around.”
The incident was also the subject of social media posts.
Findlay and two others – one a neighbour of the property where the incident was understood to be taking place – were stuck at the tavern while the police operation continued, he said just before 11pm.
However, he felt safe, Findlay said.
“We’re just chilling out waiting.”
The 37-year-old man is due to appear in Hamilton District Court today on a charge of presenting a firearm/restricted weapon.
