SH1 through Wellington's Ngauranga Gorge fully re-opened after land slip
A land slip in Wellington's main arterial route, the Ngauranga Gorge, which caused ongoing traffic problems, was all clear for peak traffic on Tuesday morning.
The slip, which brought rocks crashing down onto State Highway 1 just after midday last Tuesday, closed five of the six lanes north of Wellington, including all three southbound lanes.
Mark Owen, the New Zealand Transport Agency's Wellington transport systems manager, said work to remove an overhanging rock was now complete.
The agency reopened the southbound lane of SH1 closest to the slip in time for peak morning traffic on Tuesday, after the removal of residual material and a final tidy up of the lane and footpath.

Further work was needed to secure more netting to the slip site, which would be put up outside of peak traffic hours on Tuesday or Wednesday, weather permitting.
"We're really pleased with the progress that's been made, with contractors working day and night to secure the slip site and keep people moving," Owen said.
Over the next couple of days there would be more short-term full closures of the southbound lanes with rolling traffic control - a safety requirement to allow access for equipment to be dropped at the site, he said.
"We're really pleased that people have been taking great care when the lanes have been closed to allow the work to go ahead, and ask that drivers stay patient so the work can be completed."
