Auckland's City Rail Link has had another budget blowout, and is now asking for another billion dollars.
The project got underway in 2017, with a price tag of $3.4 billion.
It will now cost at least $5.4 billion and is running a year behind schedule. The company delivering the project has now had to go back to Auckland Council and the government - who are jointly funding it - to ask for the money to continue.
Felix Walton reports.
