Auckland’s City Rail Link will open to passengers on Sunday 13 September, ending a guessing game that has run for the best part of a year and setting a firm date for the biggest change to the city’s public transport network in generations.
The date was supposed to be revealed at 9am on Thursday by Transport Minister Chris Bishop and Auckland Mayor Wayne Brown, speaking outside the new Karanga-a-Hape station. It got out early. Before dawn, Auckland Transport billboards carrying the opening date appeared around the city centre, and photographs of them spread quickly.
An Auckland Transport spokesperson told RNZ the billboards had gone up in error and were only meant to be displayed after the official announcement. “It was a mistake by the billboard provider,” they said.
The $5.5 billion project is the largest transport infrastructure job New Zealand has undertaken. It runs twin tunnels of 3.45 kilometres, at points 42 metres below the surface, from the waterfront up through the central city to the Western Line at Mount Eden. Two entirely new underground stations sit along the route, Te Waihorotiu in the middle of town with entrances on both Wellesley and Victoria Streets, and Karanga-a-Hape with entrances at Mercury Lane and Beresford Square. Two existing stations have been rebuilt, with WaitematΔ at Britomart converted from a dead-end into a two-way through station and Maungawhau at Mount Eden given a new building and a connection to the tunnels.
Construction began with a groundbreaking ceremony in June 2016, which makes the wait a decade long. City Rail Link Limited reached practical completion at the end of June this year and handed the tunnels and stations over to Auckland Transport and KiwiRail, the two organisations that now own and run them. Everything since has been testing, certification and staff training rather than building work.
For passengers the practical difference is frequency and reach. At peak times trains will run every five minutes through the city centre and roughly every 10 minutes elsewhere on the network. Off-peak services will run every 15 minutes throughout the day, including weekends, compared with every 20 minutes at present. Converting Britomart from a terminus into a through station is the change that makes the rest of it possible, because trains no longer have to reverse out of a bottleneck before the next one can come in.
What opens on 13 September will not be the finished timetable. Auckland Transport has confirmed the network will start on a reduced transitional timetable with uneven frequencies on some lines, and build to the full service within six months. That approach was settled after congestion problems turned up during testing in January, which led to changes in how lines are routed and how the network map is drawn.
Louise Pengelly, City Rail Link operations director for train operator Auckland One Rail, told 1News in July the phased start was designed to build confidence among staff as well as passengers. “We’ll see how it goes. If we see that things are running safely and reliably, then we’ll look to increase frequency sooner than that,” Pengelly said.
Auckland Transport chief executive Stacey van der Putten said at the same event that an announcement would follow the final round of safety certification involving NZTA. “We’ll then provide a recommendation, there’ll be an announcement on opening, and that’ll give a six-week timeline for the doors to open to the general public,” she said. Counted from Thursday, 13 September lands almost exactly on that six-week mark.
Aucklanders who have spent six years with bus replacements and weekend track closures will want to know whether the disruption is over. KiwiRail chief metros officer Bevan Assink said the new track was in strong enough condition that no major works were expected for at least three years. “We’ll do our normal maintenance and inspections, and we’ll do some rail grinding and everything like that. I don’t see that it’s going to need a major intervention for something in the order of sort of three years,” he said. Routine engineering windows will continue overnight on weekdays with a longer window on Sundays, but the full network shutdowns that became a fixture of the past few years are finished.
Before the opening, Auckland Transport, City Rail Link Limited and KiwiRail are running free ticketed First Look events so the public can walk through the new stations without a train involved. Maungawhau is open on Saturday 8 August, Karanga-a-Hape on Saturday 15 August and Te Waihorotiu on Saturday 22 August. Numbers are limited and free tickets are released a week ahead of each session.
The secrecy around the date had become a story of its own. Officials repeatedly declined to name a day, saying they would not commit until regulators had signed off, and that caution drew public criticism. Auckland councillor Richard Hills said last month that people wanted at least something to work with. “Is there any way in the next couple of days that it can be announced what month? Because there are a lot of people getting upset, concerned. There’s a lot of businesses who just want hope,” Hills said.
That reluctance had a precedent behind it. Sydney’s city centre metro opening was pushed back two weeks in 2024 when regulators did not accredit the line in time, despite the project being all but ready for passengers. Melbourne gave only two weeks’ notice before its Metro Tunnel opened last November. Auckland has landed somewhere in between, with about five and a half weeks between the announcement and the first passenger service.
A Sunday was chosen deliberately. Internal advice favoured a weekend opening as a less time-pressured setting for people to get used to new stations, new platforms and a redrawn network map. The calendar narrowed the options further. Writ day for the general election falls on 4 October, term three school holidays start on 26 September, and a Bledisloe Cup test at Eden Park on 10 October would be an awkward weekend for a new network still finding its feet. Mid-September threads all of those needles.
Extra services will run on opening day above the normal weekend timetable to handle the crowds, with the first trains going out early in the morning. No large formal ceremony is planned.
Will you be on one of the first trains through the tunnels on 13 September, or do you think the reduced opening timetable takes the shine off it? Tell us in the comments below.
