This was revealed by the Family Support Centre based at the Port Moresby General Hospital (POMGEN).
The centre treats over 1000 survivors of domestic and sexual violence in a year, with about 40 patients a month.
The centre reports that more than half of the monthly survivors are children under the age of 16.
FSC also revealed that pack rapes and paedophile cases are becoming very common.
FSC clinical manager Tessie Soi said the figures are quite alarming, especially in NCD, which is known as a mini PNG.
Soi said we need to speak openly about it and encourage people to recognise that these issues are really happening in the communities.
