The helpline - which will run nationwide and toll free - will see professional counsellors taking calls 12 hours a day, seven days a week.
Those who call through will not only been given one-to-one counselling, but also information about where else to seek help locally.
ChildFund NZ chief executive Paul Brown said the hope was to help survivors deal with their circumstances but also speak out about what they've been through.
"In stark contrast to being so close to many of our favourite Pacific holiday destinations, Papua New Guinea has a staggering reputation for violence against women and children - particularly young girls,'' he said.
"Counselling is a critical aspect of this service. It can assist survivors through the immediate crisis and help stabilise emotions; provide options, information and resources; and guide them through the processes of seeking medical care, protection and legal recourse."
This hotline is about providing women with a safe channel to talk through the trauma they are experiencing and guide them in seeking the help and protection they deserve.
