Thousands of people are getting their first glimpse inside Auckland's City Rail Link tunnels.
Only 10,000 people have tickets for today's highly anticipated Walk the Tunnels event, with many more missing out on tickets.
Most of the first people inside the tunnel are families. Many are taking large family photographs at the deepest accessible point.
Access is being staggered, with people being given times to view throughout the day.
Transport minister Phil Twyford was among the first inside the tunnel at 8am.

He said he liked what he saw, and it was good to see progress on a key part of the Government's transport plan.
City Rail Link Ltd Chief Executive Sean Sweeney said he had been positively surprised by the unprecedented interest in the event.
He said while there would not be another Open Day in the near future, he was hoping for further open days for other parts of the project before the City Rail Link is completed.

In mid-2018, it was the story that captivated the world. The Wild Boar soccer team - made up of 12 boys and their coach - were trapped deep inside the Tham Luang cave in Thailand for 18 days after a flash flood saw them unable to escape. 
They were eventually rescued, with two men at the centre of the rescue who were both Australians: Dr Richard Harris and Craig Challen.
Both called on for their medical expertise - Richard is an anaesthetist and Craig and veterinary surgeon - and cave diving knowledge, a rare combination of talents that made them vital to the rescue effort.
Their role in the rescue saw them named joint Australian of the Year, and they’ve now released a book together titled Against All Odds.
However, their journey to heroism was not an easy one.
Harris told Andrew Dickens that when he was brought in to help, everyone thought that the boys would have already died. When the boys were then found, the doubts remained. "There was no way to help them escape."

He says that panic was one of the main concerns due to how long the dive would be to get the boys through the water.
"Panic in that environment is certain death, not just for the boys but for the divers as well."
Harris was then asked to sedate the boys, which he was initially negative about the plan. 
"My initial response was 'look, that's impossible. You can't render someone unconscious and then push them underwater for three hours and expect them to be alive at the end of it." 
His attitude to the plan did not change until the final boy was rescued, which he says is not a bad way to be.
He only agreed to go ahead with the plan because the other options fell away, and there were only two options: either sedating the boys, or leaving them in the cave to die "very slowly". 
"Maybe one or two might survive. It was a very grim choice." 
When it came time to rescue them, Harris stayed in the cave where the boys were trapped in order to sedate the boys and dress them in their diving gear.
There was only one occasion where he had to move a boy through the cave. He describes the water like "chocolate milk" as they couldn't see anything. The boys were "packaged up" and "streamlined" to make it easier to move them, with their hands tied behind their backs and their feet bound together.
"Morally, this stuff just feels reprehensible it's hard to describe how you feel doing this stuff to an unconscious child." 
One of the hardest things Harris had to do was leave every night, leaving the boys to their fate. He says he knew that if there was another heavy rain, the cave would flood again and no one would be able to get to them. 
"I felt like I was alright, I was going back to my hotel, and leaving these kids to their death."
When the final boy was rescued, Harris' initial joy was dampened when he spoke to his wife and learnt that his father had died that afternoon. He says he has never been on "such an emotional rollercoaster", but his father had a cancer diagnosis so his death was a blessed relief.
Asked if his father knew his son was being a hero, Harris says that he does not like to use the word, and that he and his colleagues find the whole situation "acutely embarrassing".
"I've worked in the emergency services a fair bit and you just do your job. We knew this was different and unusual, but it did feel like we were just doing a job. These kids I looked at as patients in a way."

Long-serving Green Party MP Gareth Hughes is retiring from national politics.
The 38-year-old assumed office in 2010 and has been in Parliament longer than any of his colleagues.
Greens co-leader James Shaw wished Hughes all the best
Hughes had been a leading member of the Greens caucus for a decade, Shaw said.
"We will miss him after he retires from Parliament next year. Gareth, I wish you all the very best," Shaw said on Twitter.
Hughes told Stuff he wouldn't seek re-election in 2020 and that the current Government had not been "transformational".
However, NZ Herald political editor Audrey Young told Andrew Dickens that it is not too severe of a criticism 
"He's a hell of a nice guy, but I think he's leaving politics before he was pushed. I think he was due to be sliding down the Greens list next year."

LISTEN TO FRANCES COOK AND LIAM HEHIR DEBATE MICHAEL BLOOMBERG WITH ANDREW DICKENS ABOVE, AS THE WASHINGTON POST'S DAN BALZ ANALYSES BLOOMBERG'S CHANCES
Michael Bloomberg was not the talk of New Hampshire on Friday.
Robert Pauwels, an undecided independent voter, was waiting for former Vice President Joe Biden to appear at a town hall in Franklin that evening. Asked about Bloomberg, he shrugged. "I don't think he has a chance," he said.
Others who had turned out to see candidates in the Granite State were similarly unenthusiastic in their reactions to the news that the billionaire and former mayor of New York plans to seek the Democratic presidential nomination.
A woman in Franklin called the decision "ridiculous" and said she thought it was prompted by a desire to "interfere with the process." In Stratham, a man wearing a badge supporting South Bend, Indiana, Mayor Pete Buttigieg scoffed. Bloomberg wouldn't draw enough support to become even a spoiler in the nomination battle, he said.
In Concord, Biden offered gracious words for Bloomberg after filing for next year's primary but left no doubt he's ready for the competition: "Michael's a solid guy and let's see where it goes. I have no problems with him being in the race." He was quick to add, "The last polls I looked at, I'm pretty far ahead.
Buttigieg, in a brief Saturday morning interview before continuing his bus tour of the state, said the voters he's been talking to are in the process of looking at the existing field and trying to narrow it down, albeit they are focused on "which one of us is best to beat Donald Trump." As for a hunger for someone new to join the race, Buttigieg said, "That's not something I've heard from voters."
All the early reactions might be premature, given the fluidity in the Democratic race. Bloomberg's apparent decision to run for president has for now sharpened the discussion about the qualities of the current candidates and the party's prospects in November 2020.
A Bloomberg entry is seen both as a vote of no confidence in Biden and as evidence that the donor wing of the party, or the moderate wing of the party, or the establishment wing of the party is truly terrified that Sen. Elizabeth Warren, D-Mass., has gained the upper hand in the nomination contest.
The unsettled nature of the Democratic nomination campaign has left many Democrats wondering whether any of their candidates can go the distance. That's the ground on which Bloomberg is building his candidacy - the deep-seated fear that Trump, for all his problems, may be more than equal to the task of winning a second term.
At the same time, many Democrats with long experience in presidential politics are baffled by Bloomberg's decision. Oh, they know he has long wanted to be president, that he looked at it seriously in several recent cycles, only to pull back and conclude that he couldn't win, and for Bloomberg, winning is the thing he wants.
Almost every attribute Bloomberg brings to the campaign is already spoken for by the current field. A mayor? There's Buttigieg or former Newark mayor Sen. Cory Booker, D-N.J., or former San Antonio Mayor Julián Castro. A moderate? Well, there's Biden and Buttigieg and Sen. Amy Klobuchar, D-Minn., and Sen. Michael Bennet, D-Colo., and Gov. Steve Bullock of Montana and . . .
He's a billionaire willing to spend a fortune. So is Tom Steyer. He is a septuagenarian, if people are looking for older candidates, but so are Biden, Warren and Sen. Bernie Sanders, I-Vt. He's a successful business executive. Andrew Yang is a business success as well.
One of Bloomberg's signature issues that might appeal to the Democratic base is gun control. Former congressman Beto O'Rourke made that his signature issue after the horrific mass shootings in El Paso, Texas, and Dayton, Ohio, calling for mandatory confiscation of assault weapons. He dropped out a week ago. Another of Bloomberg's issues is climate...

Blue Moon by Lee Child. This is Jack Reacher # 24. This time he comes across an elderly couple who’ve got themselves into a financial mess by borrowing money for life saving surgery for their daughter, and tied up with a couple of dangerous gangs – the Albanians and the Ukrainians, who are not best pleased to have Jack on their patch. Great stuff.
Exposure by Robert Bilott. In the spirit of Erin Brokovich, this is the author’s true story – how when working as an environmental lawyer, he found that runoff from a DuPont landfill, and the production of Teflon at a local plant was causing catastrophic damage in West Virginia. DuPont is such a big employer there that nobody would listen and the authorities took no action - the author discovered the company had known about it for 60 years, while state officials turned a blind eye. DuPont eventually paid more than a billion New Zealand dollars in penalties and reparations. This is about corporate malpractice and one man’s 20 year crusade.
