No one

Not me, but that surprises nobody.

"most recent estimate of $3.5 to $4 billion – tho possibly higher now – the Warkworth to Te Hana motorway will be the single most expensive roading project NZ has ever built (so far)."
The ferries & wharves were going to cost $3b. Willis said they were too expensive & cancelled. Cf to these roads?

So, add on the break fees for the Korean ferries, and it's heading quite high. For inferior specced products delivered muh later.
