MSSA meaning in Governmental ?

Answer:

What is Military-Style Semi-Automatic mean?

Military-style semi-automatic firearms in New Zealand are those semi-automatic firearms known in the United States as "assault weapons". The phrase is often abbreviated as military-style semi-automatic (MSSA). A New Zealand firearms licence-holder requires an E Category endorsement on their licence before they can possess this type of firearm, and a police-issued permit to procure each firearm is required. Arriving at a clear definition and common understanding of which semi-automatic firearms have a military-style configuration has dominated debate about gun-control legislation in New Zealand since 1992.

The phrase was introduced as part of the 1992 amendment to the Arms Act that was intended to impose stricter controls on military style semi-automatic firearms following the 1990 Aramoana massacre where a lone gunman, who held a lifetime firearms licence, killed 13 people using several different firearms, including a semi-automatic rifle that he fired from the hip at police.

Some semi-automatic firearms that have been sold in a sporting configuration, so that they can be possessed by a person holding a standard (A Category) firearms licence, without endorsements, can be converted to an MSSA simply by adding or changing one part, such as a larger magazine or flash suppressor. If a person intends to convert an A Category firearm that they already possess, they need to obtain an E Category endorsement before making the conversion to their firearm, because merely having parts in the person's possession to make the conversion possible makes an A Category semi-automatic firearm an MSSA.
