After years of construction, more than $5 billion and an almost constant refrain of "when is it opening?" — Auckland Transport has confirmed the day of the week the City Rail Link will open to the public. It's a Sunday.
The official confirmation of that piece of the puzzle came ahead of the CRL clearing one of its final hurdles today - ownership of the link passes from the Link Alliance construction consortium to KiwiRail and Auckland Transport (AT) this afternoon.
But what AT has not confirmed is an opening date.
Officials have been at pains in public not to commit to a specific date, but it's understood the earliest feasible dates in planning were from mid-August onwards.
The opening was always set to fall at least six-to-eight weeks after today's handover of the new CRL tunnels and stations - a window driven by the need to give rail staff notice of major roster changes affecting how train crews work their shifts.

That notice period helps narrow things down. So which Sunday?
The earliest possible date is August 16. After that, the contenders are August 23, August 30, September 6, September 13 and September 20. Auckland Mayor Wayne Brown told The Spinoff last month that he expected an opening around this period.
Before then, the rail network will close over the Matariki weekend from July 9, so crews can carry out a final network-wide "dress rehearsal" of the new timetable. AT chief executive Stacey van der Putten called the closure "one of the last big pushes".
The opening Sunday will have extra services above the normal weekend timetable to handle the expected crowds, but with no large formal ceremony planned.
According to an AT local board briefing last week, the first trains will run early in the morning, offering opportunities for media and train enthusiasts, known as gunzels.
'Paper project' still to be finished
In an update to councillors last month, CRL chief executive Pat Brockie said the final stages of the project would be the "paper project".
That covers the safety assurance work with rail regulator NZTA — "their assurance and sign off or certification is critical," Brockie said — as well as the code-of-compliance certification the three new station buildings need from the council.
Those are the kinds of sign-offs that delayed the opening of Sydney's city centre metro in 2024, after authorities there failed to accredit the new line in time despite the project already being "99% ready" for passengers. That line opened two weeks later.
Several factors are likely to shape which Sunday is chosen in Auckland, aside from the practicalities of putting the finishing touches on the project.
Officials are expected to avoid the depths of the election campaign period, with writ day on October 4 - any major rail disruption in the opening weeks would be an unwelcome backdrop heading into the early-November vote.
The Term 3 school holidays, which begin on September 26, are also a consideration.
AT was advised last year in a briefing that "non-commuter times" such as long weekends or school breaks would be suitable for an opening at a less-patronised time.
But the later school-holiday Sundays edge closer to both the election campaign and a Bledisloe Cup test at Eden Park on October 10 - a big event that officials would likely want to keep clear of while the new CRL train network finds its feet.
Internal assessments from last year suggested a weekend was favoured due to "a less time-pressured environment for people to familiarise themselves" with the new service.

How unusual is it not to have an opening date?
Officials have compared Auckland's train tunnel to others recently opened, most notably in Australia, which has had a pipeline of new rail projects.
Melbourne public transport advocate Daniel Bowen said governments and officials might often be reluctant to set a firm date too far in advance, for fear of having to move it.
"People often look at the construction, and they see that the construction's finished, so therefore, shouldn't it open soon?" he said.
"Even when you see the above-ground - if you haven't seen inside the stations, then you may not realise there's fit-out and new equipment testing and staff training."
The Australian advocate pointed to the Sydney example. "They had announced an opening date, and then they didn't get sign-off from all the relevant regulators in time for that date, and so had to put it back," Bowen said.
He said the delay "caused some embarrassment" at the time, though it had since faded from public memory. "In retrospect, the Sydney Metro has been incredibly popular, so I suspect most people have forgotten it."
Melbourne, meanwhile, ran a "soft launch" of its Metro Tunnel in November before the full opening in February. The opening date was only announced with two weeks' notice.
Bowen, a spokesperson for the Public Transport Users Association Victoria, said authorities started by running trains through the tunnel on weekends and off-peak.
"They didn't want a packed peak-hour train getting stuck in a tunnel," he said. "They wanted to minimise any risk, so that if there was a breakdown, large numbers of passengers wouldn't be affected."
'Good progress' - AT
A spokesperson for Auckland Transport told 1News last week: "It will be in the second half of this year and as with most AT public transport changes, the first day will be a Sunday.
"We are making good progress through emergency and safety testing, applications for code compliance certificates for the stations have been lodged and are being processed," they said in a statement.
"We will set a date when we have confidence everything will be ready to open new stations and services safely and reliably, including all regulatory approvals. This will be announced 6-8 weeks out, which allows time for the final steps ahead of opening".
A July 9 dress rehearsal will simulate day one CRL operations and the future weekday timetable, testing that timetable data feeds correctly into customer information displays - including more than 200 screens across stations and the AT Mobile app.
An earlier test in April gave AT confidence it could run the planned timetables reliably, the press release said, confirming the plan to open with a temporary timetable and build to full frequency within six months - "common practice on major rail projects worldwide".
Discussions of a temporary timetable were publicised after significant congestion issues were identified during "day one timetable" testing for the CRL in January.
