They have also today released a policy position on water infrastructure and services calling for budget separations of local councils and any future water entities.
Infrastructure New Zealand advocacy and strategy lead Martina Moroney said maintaining the status quo could not continue.
“If the current situation is left to continue, New Zealanders will face significant social, economic and environmental costs along with ongoing risks to public health.”
Moroney said financial independence from councils will allow them to borrow to fund significant backlogs in asset renewal and replacement.
She said in the meantime it was likely that central government will need to consider credit wrapping council water services and providing bridging funding until the new entities were established and self-sufficient.
Infrastructure NZ was also recommending volumetric water charges be explored so that, like other utilities such as telecommunications and electricity, consumer demand could be better managed and a direct service-related revenue stream created.
