The work was an early stage of what is ultimately expected to be a major spend on improvements to State Highway 5 between Taupo and the highway's intersection with SH2 north of Bay View.
Some of the future work was outlined in today's announcements by the NZTA.
Work started in mid June to improve the entrance to Tarawera Cafe.
An NZTA spokesperson said the entrance was being made into a single accessway, rather than separate in and out accessways, to prevent confusion.
It also moved the entrance to the south to provide better view of traffic in both directions on the highway.
Reshaping the road into the cafe to reduce the slope and widening the left turn slip lane for southbound traffic was also taking place, and electronic signs to warn vehicles turning in and out of the cafe were also being installed.
Andrew said that despite the traffic flow being light he has already had feedback from truck drivers noticing the improved entrance and exit, when some drivers would not have stopped in the past because of the risk.
"It is all green lights really," he said. "With spring coming on we've got to look towards things getting better."
