Violent crime is rare in New Zealand and police do not usually carry guns, though mass shootings have occurred previously. Here is a list of some previous incidents.

1997

* A lone shooter killed six people, including his father, and wounded four others in the ski-lodge hamlet of Raurimu. He was tried and found not guilty by reason of insanity.

1994

* Seven members of the Bain family were shot dead in Dunedin, South Island’s second largest city. A surviving son was convicted of their murders in 1995, but later acquitted at a retrial in 2009 and awarded a payout of almost NZ$1 million ($680,000).

1992

* At a farm outside Auckland, Brian Schlaepfer shot and stabbed six members of his own family before killing himself with a shotgun.

1990

* A gun-mad loner killed 13 men, women and children in a 24-hour rampage in the tiny seaside village of Aramoana. He was killed by police. It prompted a modest tightening of gun laws.

1943

* Forty-eight prisoners-of-war and a guard died when officers opened fire on rioting inmates at a camp holding Japanese soldiers captured during the Guadalcanal Campaign. A court martial determined prisoners were responsible, but no charges were pressed.
