Strangulation is to be made a specific crime after a recommendation by the Law Commission that has been welcomed by Justice Minister Amy Adams.
Ms Adams said strangulation was "an abhorrent act", that was a deeply personal and intimidating form of violence.
"In a domestic violence context, it's more than just a physical attack and can have a devastating and long-lasting psychological impact on victims," Ms Adams said.
Family violence victims who have been strangled previously are seven times more likely to end up being killed than those who have suffered other non-strangulation forms of violence.
However, at present non-fatal strangulation is either not prosecuted, or offenders are charged with only generic assault offences.
