The road, which is a key link to towns like Whangamatā and Hāhei, was damaged earlier this year when its bridge was washed out in storms.
The Transport Agency held meetings this week to discuss timelines for repair work, with the road on track to open on 31 March
Thames-Coromandel Mayor Len Salt said while the road closure had hit the economy hard, there was a silver lining.
"So they're pumping a lot of time and effort and funding into getting the rest of that road into really good shape."
Salt said the local economy had lost around $30m since its closure.
