CEO Robin Fleming said most of their operations remain open, while severely affected areas have been closed due to ongoing aftershocks being experienced.
They include Moro (Southern Highlands Province), Mendi (SHP) and Tari (Hela).
He said all staff in the area have been accounted with relief packages sent to them.
“By and large most branches have been open, and continue to provide services where we can. And we’ll be making a formal announcement and relief packages later today.
“Our thoughts are with those affected,” he said.
