NRC received 2007 submissions from an online submission platform www.toko.org.nz, set up by Greenpeace for either groups or individuals to make representation to the environment watchdog.
Of the nearly 5000 submissions received by both councils, 344 submitters wish to appear before the hearing commissioners.
Legally, submitters have a right to withdraw their wish to be heard anytime.
Both councils last month rejected a written request by Arapohue resident Carol Donovan on behalf of those opposed to Tegel's plan that the deadline for public submissions be extended.
A protest march was organised in Dargaville town by the Dargaville Chicken Farm Community Information Group three weeks ago following four public meetings where locals were urged to lodge their submissions.
Residents of Mititai and Whakahara Rds in Arapohue are mostly concerned about the smell and possible devaluation of their properties if the broiler chicken farm was set up.
