Provincial election manager Anton Iamau confirmed that polling officials are now doing pre-counting of ballot papers in Wabag Town.
Iamau said earlier that all 1,156 ballot boxes arrived in the province last week.
He said there are enough security personnel of both police and defence force on ground to provide security during polling.
Enga consists of five electorates, 411 polling teams, 364 Wards and 18 LLGs.
After the pre-counting is done, the ballot boxes will be distributed to the five electorates.
