Repairs to Skippers road after slips and washouts during winter have cost the Queenstown Lakes District Council $193,000.
The council was forced to close the 22km road in August because of urgent repairs needed to an undermined section, about 1km from the turn-off on the Coronet Peak access road.
Heavy rain in May had also scoured the spot, leaving it in a fragile state.
The council's roading manager, Ian Marshall, said the repairs were completed in five weeks with the road closing intermittently over that time.
He said the repairs were carried out on three sites.
Two areas where slips had blocked the road were "rock bolted".
"We drilled holes and inserted bolts to hold the rock together. We also had to rebuild and stabilise part of the road that had eroded away and fallen down the gully due to water," he said.
The Historic Places Trust had been consulted and an archaeologist had prepared a report on reinstating the original stack stone walls.
Mr Marshall said the stone work was due to start in mid-January.
The walls were originally built in 1883, and the council and the trust had agreed on a suitable stonemason to carry out the work.
The road dates back to 1863, soon after gold was discovered in the area.
