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.
The five electorates are Wabag, Kandep, Kompiam-Ambum, Lagaip-Porgera and Wapenamanda.
There are 411 polling teams in the province and the biggest electorate is Lagaip-Porgera, with 119 polling teams.
Iamau is yet to confirm when the one day polling will commence.
