"All we've done is produce a space for the community and hapu to voice their concerns," Ms Emile said.
"It's a forum with information for everyone - for and against. People like us can be intimidated by this sort of thing, the page gives us a voice and we can speak without fear of intimidation," Ms Parata said.
The trio have also organised a link to an online petition opposing the project which has also been set up, called "Stop the Eastern Arterial".
The petition can be found at avaaz.org and has more than 360 signatures.
A hui has been called at Hurungaterangi Marae for this Sunday at 1.30pm for people affected by the proposed road to plan future protests.
The next step in the process is for the NZTA to lodge a "Notice of Requirement" (NoR) for the works with the Rotorua District Council and it is expected to do so before the end of June.
Technically, the council could decline the NoR, but Rotorua Mayor Kevin Winters says such a decision could be appealed and ultimately be decided in the Environment Court.
