The It's not OK Campaign website says:

Signs that someone is in danger of being killed by their partner are often missed by friends, family and others until it is too late. … These danger signs are either not seen, or dismissed as not serious - yet we know that certain signs mean that a victim is highly likely to be killed by her partner.  We all need to know these danger signs so we can keep people safe.

It also says:

About half the homicides in NZ each year are family violence related. One woman is killed by her partner or ex-partner every month.  About half of those victims will be murdered during or following separation from their partner. Never assume that a victim is safe because she is planning to leave or has just left a violent relationship.

The campaign encorages people to "Take action – you may be the only one who does." Contact details for services are provided.
