Women staff can now take four months fully paid maternity leave while the men are entitled to 15 days paid paternity leave.
Employees only must complete their six month-probation to be entitled to the parental leave.
The workers have applauded St Barbara for introducing the ground-breaking policy.
“It is a great incentive for mothers and babies, especially those with complications. I believe it is a first in PNG and I say how lucky my women colleagues are for being employed by St Barbara,” said accountant and local Tabar islander Paskalis Maradangoi.
