There's growing calls for New Zealand to get realistic about our infrastructure.

The Infrastructure Commission's released a 30-year draft plan today  for future builds and upgrades to roads, hospitals and public buildings.

Commission CEO, Geoff Cooper, says a large issue is our lack of spending on maintaining existing infrastructure.

He explained we are running our assets into the ground, so repairs cost more - leaving less money for everything else.
