They are transported by helicopter. Non-delicate materials—booth dividers, pencils, and so on—are delivered by automobile. Between 24 and 48 hours before election day, delicate materials, including ballots, are distributed. The ballots are kept at the MINUSTAH military base. Therefore, we distributed the ballots first at the MINUSTAH military base well before election day, and one or two days before the elections, the ballots are collected at the MINUSTAH military base and taken by helicopter to remote areas.
