The state highway north of Kaikoura has reopened for the first time since last year's earthquake, with a long queue of traffic already waiting to take the first trip.
Drivers were warned to expect delays as soon as the stretch of State Highway 1 between Picton and Christchurch opened on Friday, one year, one month and one day after a 7.8 magnitude quake rocked the seaside town.
An "extensive queue" had built ahead of the 1.30pm opening, the NZTA said.
Earthquake recovery manager Tim Crow said it marked the achievement of 1700 crew members who had worked to piece back together the area's infrastructure.
"It's also been a long, tough year for the communities along the route," he said.
