There's confidence there'll be no issues when Auckland's long awaited City Rail Link opens this weekend.
The $5.5 billion project opens on Sunday, with twin three-kilometre tunnels, two new underground stations, and an entirely new timetable for Aucklanders.
It'll also see three new main services: the East West, South City, and Onehunga West lines.
KiwiRail Chief Executive Peter Reidy told Mike Hosking they've done significant testing and run the trains over the last few months, and have had international experts look at the project as well.
He says of any large infrastructure project he's been involved in, this would be one of the best in terms of a readiness plan before it goes live.
