BJP leader Kiren Rijiju is fighting against sitting Congress member Takam Sanjoy from Arunachal West, while union minister and Congress leader Ninong Ering, who is re-contesting from Arunachal East, faces the BJP's Tapir Gao.
In Nagaland, around 82.5 percent of the over one million electorate cast their votes for the state's lone Lok Sabha constituency. No untoward incident was reported from anywhere in the state, which borders Myanmar.
In the 2009 election, the turnout was around 90 percent.
Conducive weather helped voters come to the polling stations early. New voters and women were enthusiastic, officials said.
Due to security reasons, polling hours in Nagaland and Manipur was from 7 a.m. to 4 p.m, unlike the other northeastern states where votes could be cast between 7 a.m. and 5 p.m.
