Nick Leggett: Infrastructure New Zealand CEO voices concerns as City Rail Link costs blow out

There's serious concerns political bickering is ballooning the cost of New Zealand's major construction projects. The cost of Auckland's City Rail Link has risen over the past decade from $3.4 billion dollars to almost $5.5 billion. Outgoing chief executive Sean Sweeney told TVNZ the lack of a clear and consistent pipe line, due to political uncertainly, is the biggest factor driving up costs. Infrastructure New Zealand chief executive Nick Leggett says we're really bad at pushing go on these projects, and that's driving up efficiencies. "We don't have the guarantee across political cycles and funding cycles to lock them in and get the efficiency that a small country like New Zealand desperately needs."  LISTEN ABOVE  See omnystudio.com/listener for privacy information.
