The Aramoana massacre was a spree shooting that occurred on 13 November 1990 in the small seaside township of Aramoana, New Zealand. Resident David Gray, a 33-year-old unemployed man, began indiscriminately shooting people in the township with a scoped semi-automatic rifle, after a verbal dispute with his next-door neighbour. He shot neighbours and a family visiting the township, and killed 13 people, including local police Sergeant Stewart Guthrie, one of the first responders to the reports of a shooting. After a careful house-by-house search the next day, police officers led by the Anti-Terrorist Squad (now known as the Special Tactics Group) located Gray and shot him dead as he came out of a house firing from the hip.
