Mrs Collis said she expects there will have been more movement at the cliff face after last week's heavy rainfall.
"NZTA will also talk about the work under way on the Saddle Rd and I'm expecting quite a bit of discussion on the options for State Highway 3 through the gorge, medium and in the longer term."
Mrs Collis said NZTA also wanted to hear from the local community and discuss where to from here.
"There will also be discussions on how can we all work together," she said.
However, Mrs Collis conceded there may not be time to answer everyone's questions and she's encouraging people to forward their questions to her for discussion after the meeting.
And the Dannevirke Chamber of Commerce is asking members affected by the closure to email them with details of any current implications for their business.
"The closure means there could be major consequences to the region's long-term economic growth, through increased time, labour and other costs," chair Susan Berry said.
"By documenting the concerns and difficulties of our chamber members we will provide a strong voice for businesses and the community of the Tararua region. Ultimately, we are seeking urgent consultation for a long-term solution."
* You can email sueberry@xtra.co.nz with any implications for your business.
* The public meeting in Woodville begins at 7pm in the Woodville Sports Stadium.
