The Transport Agency has paid a contractor an extra $4 million over delays to a cycleway in Lower Hutt.
The Petone to Melling cycleway has been delayed till next year and its forecast cost has been increased to $63m.
Waka Kotahi said it settled claims over several project extensions from the contractor Fulton Hogan last year.
Some delays were due to Covid-19, but documents showed a lack of planning and investigation has forced several redesigns.
The agency said taxpayers were no longer exposed following the settlement of the claims and the $4.05m payment.
