IFES: Elections in Papua New Guinea: 2017 National Elections

 “Once polling closes, polling teams transport the ballots in sealed ballot boxes to counting centers where they will be counted sequentially in the presence of scrutineers. Each constituency is assigned a specific counting center within the electoral district or province where voting took place; in the Highlands region, for example, all counting centers are centralized in the provincial capital. At the counting centers, votes will be sorted, counted and tabulated under the supervision of the returning officer and assistant returning officer and with support from sorters, counters, runners, tally men and recorders. Candidates may appoint one scrutineer to observe counting in their place and raise objections when necessary. […] While these are manual processes, data processing officers will use tablets to electronically record results and images of the forms throughout the counting process. The captured data and images will be automatically transmitted to the Papua New Guinea Electoral Commission (PNGEC) so that results can be efficiently aggregated, verified and announced to the public through the PNGEC’s media center and website.”
