Winston Peters says logic has prevailed, as he confirms our new Cook Strait ferries are coming in under $2 billion dollars. 

The new Interislander vessels are expected to arrive in 2029 under budget.

The Rail Minister claims it's saved the taxpayer more than $2 billion on the canned mega-ferries project. 

Peters says he's confident the Government's done the right thing.

"This is common sense we're applying here, there are contingencies in our plan as well. And to cover off any concerns you've got...we've got together a hard-nosed team."
