A section of the Auckland City Rail Link will be open to the public next month.
City Rail Link revealed on Wednesday it will hold an open day, giving Aucklanders the opportunity to walk a section of the 3.45 kilometre-long tunnels being built for the project.
Chief executive Dr Sean Sweeney says it's a rare opportunity to enjoy a "brief snapshot" of New Zealand's largest-ever infrastructure project.

"We have a lot to celebrate," Dr Sweeney said.
He said it was a chance to show off some of the "outstanding engineering" behind the project.
It's hoped it will be an experience people will remember for the rest of their lives, Dr Sweeney said.
"It's a great chance for us to say, 'thank you' to people for the support they are giving the project."
Work on the rail link started in early 2016, with about four more years of work still to come.
